(Main)Aggregates for unbound and hydraulically bound materials for use in civil engineering work and road construction
Aggregates for unbound and hydraulically bound materials for use in civil engineering work and road construction
This European Standard specifies the properties of aggregates and filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in hydraulically bound and unbound materials for civil engineering works and road constructions. It covers aggregates having an oven dried particle density greater than 2,0 Mg/m3 (2000Kg/m3). It also covers recycled aggregates with particle densities greater than 1,50 Mg/m3 (1 500 kg/m3) with appropriate caveats
and recycled fine aggregate with appropriate caveats. A list of the source materials that have been considered and indicating those which are within the scope of this standard is given in Annex A (normative). Requirements for the evaluation of conformity of the products to this European Standard are given in EN 16236. It incorporates a general requirement that aggregates will not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination. The tables in this standard include categories which are common across the four main aggregate standards: EN 12620, EN 13043, EN 13139 and EN 13242. Not all of these categories are appropriate for aggregates for use in hydraulically bound and unbound materials for civil engineering works and road constructions. Categories, notes, comments etc, which are shown grey shaded should not be used for aggregates for use in hydraulically bound and unbound materials for civil engineering works and road constructions. Aggregates used in construction should comply with all the requirements of the relevant European Standards for aggregates. These standards include comprehensive and specific requirements for natural aggregates, iron and steel making slag and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constitution of recycled aggregates. For materials from some other secondary sources, however, work is ongoing and the requirements are incomplete. In the meantime, such materials, when placed on the market as aggregates, should conform fully to this standard but may also be required to conform to specific relevant additional requirements at the place of use. Additional characteristics and requirements may be specified on a case by case basis depending upon experience of use of the product, and defined in specific contractual documents. NOTE 1 Requirements for lightweight aggregates are specified in prEN 13055. Requirements for the declaration of the potential of aggregates to release regulated dangerous substances are currently under development. Until such time as these are finalised, attention should be paid to requirements at the place of use. NOTE 2 Requirements for hydraulically bound and unbound materials for civil engineering works are specified in EN 13285 and are not therefore covered in this standard. EN 13285 does however call up the general requirements of EN 13242 for the aggregates.
Gesteinskörnungen für ungebundene und hydraulisch gebundene Gemische für den Ingenieur- und Straßenbau
Diese Europäische Norm legt die Eigenschaften von Gesteinskörnungen und Füllern fest, die durch Aufbereitung natürlicher, industriell hergestellter oder rezyklierter Materialien sowie Mischungen solcher Materialien für die Verwendung in hydraulisch gebundenen und ungebundenen Gemischen für den Ingenieur- und Straßenbau gewonnen werden. Die Norm deckt ebenfalls rezyklierte Gesteinskörnungen mit einer Dichte zwischen 1,50 Mg/m3 (1 500 kg/m3) und 2,00 Mg/m3 (2 000 kg/m3) ab. Anhang A (normativ) enthält ein Verzeichnis der berücksichtigten Ausgangsmaterialien, die im Anwendungsbereich dieser Norm liegen. Diese Europäische Norm enthält ebenfalls die Festlegung, dass ein Qualitätskontrollsystem für die werkseigene Produktionskontrolle einzuführen ist sowie Festlegungen für die Bewertung der Konformität von Produkten nach dieser Europäischen Norm. Diese Europäische Norm gilt nicht für die Eigenschaften ungebundener Gemische nach EN 13285. Die Norm enthält die allgemeine Anforderung, dass die Freisetzung gefährlicher Stoffe die in der für das Material einschlägigen Europäischen Norm maximal zulässigen Grenzwerte bzw. die nach den nationalen Bestimmungen des Bestimmungsmitgliedstaats zulässigen Grenzwerte nicht übersteigen darf (siehe ANMERKUNG 3). ANMERKUNG 1 Gesteinskörnungen, die in hydraulisch gebundenen und ungebundenen Gemischen für den Ingenieurbau verwendet werden, sollten mit allen Anforderungen dieser Europäischen Norm übereinstimmen. Diese Normen enthält umfassende und spezifische Anforderungen an natürliche Gesteinskörnungen, Hochofenstück- und Stahlwerksschlacken und rezyklierte Gesteinskörnungen, die sich zum Beispiel mit der Raumbeständigkeit einiger Basalte, der Volumenzunahme bestimmter Schlacken und der Zusammensetzung von rezyklierten Gesteinskörnungen befassen. Die Arbeiten an Materialien aus einigen anderen sekundären Quellen sind jedoch noch nicht abgeschlossen und die Anforderungen sind unvollständig.
Granulats pour matériaux traités aux liants hydrauliques et matériaux non traités utilisés pour les travaux de génie civil et pour la construction des chaussées
La présente Norme européenne spécifie les caractéristiques des granulats, y compris celles des fillers, élaborés à partir de matériaux naturels, artificiels ou recyclés et des mélanges de ces granulats destinés à être utilisés dans la fabrication de matériaux traités aux liants hydrauliques et matériaux non traités utilisés pour les travaux de génie civil et pour la construction des chaussées.
Elle s'applique aux granulats dont la masse volumique réelle des particules séchées à l’étuve est supérieure à 2,00 Mg/m3 (2 000 kg/m3). Elle s'applique également aux granulats recyclés dont la masse volumique réelle est supérieure à 1,50 Mg/m3 (1 500 kg/m3), avec les mises en garde appropriées, ainsi qu’au sable recyclé, avec les mises en garde appropriées.
Une liste des origines des matériaux qui ont été prises en considération et relèvent du domaine d'application de la présente norme est donnée à l'Annexe A (normative).
Les exigences relatives à l’évaluation de la conformité sont spécifiées dans l’EN 16236.
La présente norme intègre une exigence générale stipulant que les granulats ne doivent dégager aucune substance dangereuse dont les valeurs d'émission dépassent les niveaux maximaux admissibles spécifiés dans une Norme européenne pertinente pour le matériau ou dans la réglementation nationale de l'Etat membre de destination.
Les tableaux de la présente norme contiennent des catégories qui sont communes aux quatre principales normes relatives aux granulats : EN 12620, EN 13043, EN 13139 et EN 13242. Ces catégories ne sont pas toutes appropriées pour un usage des granulats dans les matériaux traités aux liants hydrauliques et matériaux non traités utilisés pour les travaux de génie civil et pour la construction des chaussées. Les catégories, notes, commentaires, etc. qui sont grisés ne devraient pas être utilisées pour les applications dans les matériaux traités aux liants hydrauliques et matériaux non traités utilisés pour les travaux de génie civil et pour la construction des chaussées.
Les granulats utilisés dans la construction doivent respecter toutes les exigences des Normes européennes concernées. Ces dernières contiennent les exigences générales et particulières relatives aux granulats naturels, au laitier de haut fourneau et d'aciérie et aux granulats recyclés, et traitent par exemple de la stabilité de certains basaltes, de l'expansion de certains laitiers et de la composition des granulats recyclés.
Cependant, pour les matériaux provenant d’autres sources secondaires, les travaux sont en cours et les exigences sont incomplètes. En attendant, il convient que ces matériaux, lorsqu'ils sont mis sur le marché en tant que granulats, respectent pleinement la présente norme, mais ils peuvent aussi devoir se conformer à des exigences complémentaires spécifiques pertinentes sur le lieu d'utilisation. Des caractéristiques et des exigences complémentaires peuvent être spécifiées au cas par cas, en fonction de l'expérience acquise à l'usage du produit, et définies dans des documents contractuels spécifiques.
NOTE 1 Les caractéristiques des granulats légers sont spécifiées dans le prEN 13055.
Les exigences relatives à la déclaration du potentiel des granulats à relarguer des substances dangereuses réglementées sont actuellement en cours d'élaboration. Tant qu'elles ne sont pas finalisées, il convient de tenir compte des exigences en vigueur sur le lieu d'utilisation.
NOTE 2 Les exigences pour les matériaux traités aux liants hydrauliques et pour les matériaux non traités pour les ouvrages de génie civil sont spécifiées dans l’EN 13285 et, de ce fait, ne sont pas couvertes par cette présente norme. L’EN 13285 fait, cependant, appel aux exigences générales de l’EN 13242 pour les granulats.
Agregati za nevezane in hidravlično vezane materiale za uporabo v inženirskih objektih in za gradnjo cest
Ta evropski standard določa lastnosti agregatov in kamene moke, pridobljene z obdelavo naravnih, umetnih ali recikliranih materialov in zmesi teh agregatov, za uporabo v hidravlično vezanih in nevezanih materialih za uporabo v inženirskih objektih in za gradnjo cest. Zajema agregate s prostorninsko maso sušenih zrn, večjo od 2,0 mg/m3 (2000 kg/m3). Zajema tudi agregate s prostorninsko maso zrn, večjo od 1,50 mg/m3 (1500 kg/m3) z ustreznimi pogoji, in reciklirane fine agregate v skladu z ustreznimi pogoji. Seznam obravnavanih izvornih materialov, ki določa materiale, vključene v predmet tega standarda, je naveden v dodatku A (normativni). Zahteve za vrednotenje skladnosti izdelkov s tem evropskim standardom so navedene v standardu EN 16236. Vključuje splošno zahtevo o tem, da agregati ne smejo oddajati nobenih nevarnih snovi v količinah, ki so večje od največjih dovoljenih količin v ustreznem evropskem standardu za materiale ali v nacionalni zakonodaji države članice. Razpredelnice v tem standardu vključujejo kategorije, ki so skupne vsem štirim glavnim standardom za agregate: EN 12620, EN 13043, EN 13139 in EN 13242. Nekatere od teh kategorij niso primerne za agregate za uporabo v hidravlično vezanih in nevezanih materialih za uporabo v inženirskih objektih in za gradnjo cest. Kategorije, opombe, komentarji itd. v sivi barvi se ne smejo uporabljati za agregate za uporabo v hidravlično vezanih in nevezanih materialih za uporabo v inženirskih objektih in za gradnjo cest. Agregati, ki se uporabljajo pri konstrukcijah, morajo izpolnjevati vse zahteve primernih evropskih standardov za agregate. Ti standardi vključujejo celovite in posebne zahteve za naravne agregate, žlindro, nastalo pri pridobivanju železa in jekla, in reciklirane agregate ter obravnavajo na primer stabilnost nekaterih bazaltov, raztezek nekaterih vrst žlindre in sestavo recikliranih agregatov. Za materiale iz nekaterih drugih sekundarnih virov oblikovanje standardov še poteka in so zahteve nepopolne. Kadar so taki materiali dani na tržišče kot agregati, morajo v celoti ustrezati temu standardu in morajo biti morda skladni tudi s posebnimi ustreznimi dodatnimi zahtevami, ki veljajo na območju uporabe. Dodatne značilnosti in zahteve se lahko določijo za vsak posamezen primer glede na izkušnje pri uporabi izdelka in so opredeljene v posebnih pogodbenih dokumentih. OPOMBA 1: Zahteve za lahke agregate so določene v standardu prEN 13055. Zahteve za izjavo o kapaciteti agregatov za izpust reguliranih nevarnih snovi so v pripravi. Dokler te zahteve niso dokončno oblikovane, je treba upoštevati zahteve na območju uporabe. OPOMBA 2: Zahteve za agregate za uporabo v hidravlično vezanih in nevezanih materialih za uporabo v inženirskih objektih in za gradnjo cest so določene v standardu EN 13285 in jih ta standard podrobno ne obravnava. Vendar pa se EN 13285 sklicuje na splošne zahteve standarda EN 13242 glede agregatov.

EN 13242:2013 (E) 5 1 Scope This European Standard specifies the properties of aggregates and filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in hydraulically bound and unbound materials for civil engineering works. It also covers recycled aggregates with particle densities between 1,50 Mg/m3 (1 500 kg/m3) and 2,00 Mg/m3 (2 000 kg/m3). A list of the source materials that have been considered and indicating those which are within the scope of this standard is given in Annex A (normative). Requirements for the evaluation of conformity of the products to this European Standard are given in EN 16236. This European Standard does not cover the grading properties of unbound mixtures as specified in EN 13285.
It incorporates a general requirement that aggregates will not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination. The tables in this standard include categories which are common across the four main aggregate standards: EN 12620, EN 13043, EN 13139 and EN 13242. Not all of these categories are appropriate for aggregates for use in hydraulically bound and unbound materials for civil engineering works and road constructions. Categories, notes, comments etc, which are shown grey shaded should not be used for aggregates for use in hydraulically bound and unbound materials for civil engineering works and road constructions. Aggregates used in hydraulically bound and unbound materials for civil engineering works should comply with all the requirements of this European Standard. The standard includes comprehensive and specific requirements for natural aggregates, iron and steel making slag and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constitution of recycled aggregates. For materials from some other secondary sources, however, work is ongoing and the requirements are incomplete. In the meantime, such materials, when placed on the market as aggregates, should conform fully to this standard but may also be required to conform to specific relevant additional requirements at the place of use. Additional characteristics and requirements may be specified on a case by case basis depending upon experience of use of the product, and defined in specific contractual documents.
NOTE Requirements for lightweight aggregates are specified in prEN 13055. Requirements for the declaration of the potential of aggregates to release regulated dangerous substances are currently under development. Until such time as these are finalised, attention should be paid to requirements at the place of use. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

EN 13242:2013 (E) 7 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 aggregate granular material of natural, manufactured or recycled origin used in construction
3.2 natural aggregate aggregate from mineral sources that has been subjected to nothing more than mechanical processing 3.3 manufactured aggregate aggregate of mineral origin resulting from an industrial process involving thermal or other modification 3.4 recycled aggregate aggregate resulting from the processing of inorganic or mineral material previously used in construction 3.5 category level of a property of an aggregate expressed as a range of values or a limiting value Note 1 to entry: There is no relationship between the categories of different properties. 3.6 aggregate size designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D Note 1 to entry: This designation accepts the presence of some particles which are retained on the upper sieve (oversize) and some which pass the lower sieve (undersize). 3.7 grading particle size distribution expressed as the percentages by mass passing a specified set of sieves Note 1 to entry: In this standard grading categories are used and expressed as GnX/Y in which: n:
type of grading
where:
C
= coarse;
CA = coarse for asphalt only;
G
= Grit (D<4 and d>1);
F
= fine;
NG = natural graded; A
= all-in X: lower limit passing D Y: upper limit passing d 3.8 fines particle size fraction of an aggregate that passes the 0,063 mm sieve 3.9 coarse aggregate designation given to the larger aggregate sizes with D greater than 4 mm and d greater than or equal to 1 mm Note 1 to entry: Aggregates that do not fit the definitions for fine or coarse (like 1/3, 1/4 or 2/4)
are treated as coarse aggregate. SIST EN 13242:2013
EN 13242:2013 (E) 8 3.10 fine aggregate designation given to the smaller aggregate sizes with D less than or equal to 4 mm and d = 0 Note 1 to entry: Fine aggregates can be produced from natural disintegration of rock or gravel and/or by the crushing of rock or gravel or processing of manufactured aggregates. 3.11 all-in aggregate aggregate consisting of a mixture of coarse and fine aggregates with D greater than 4 mm and d = 0 Note 1 to entry: It can be produced without separating into coarse and fine fractions or it can be produced by combining coarse and fine aggregates. 3.12 filler aggregate aggregate, most of which passes a 0,063 mm sieve, which can be added to construction materials to provide certain properties 3.13 added filler filler aggregate of mineral origin, which has been produced separately 4 Geometrical requirements 4.1 General The necessity for testing and declaring all properties specified in this clause shall be limited according to the particular application at end use or origin of the aggregate. When required, the tests specified in Clause 4 shall be carried out to determine appropriate geometrical properties. When the value of a property is required but not defined by specified limits the value should be declared as an XXDeclared category, e.g., a value of say 55 for the flakiness index corresponds to FI55 (Declared value). NOTE 1 When a property is not required, a “No requirement” category can be used. NOTE 2 Guidance on selection of appropriate categories for specific applications can be found in national provisions in the place of use of the aggregate. NOTE 3 Where conformity with a category is based on a value of a property being less than or equal to a given value, conformity with a more severe category (lower value) automatically confers conformity with all less severe categories (higher values). Similarly for categories based on the value of a property being greater than or equal to a given value, conformity with a more severe (higher value) automatically confers conformity with all less severe categories (lower values). Categories, notes, comments etc, which are grey shaded, should not be used in bound and unbound materials for civil engineering works and road constructions. 4.2 Aggregate sizes All aggregates shall be described in terms of aggregate sizes using the designations d/D, and shall comply with the grading requirements specified in 4.3, except for aggregates added as fillers which shall be specified as filler aggregate. Aggregate sizes shall be specified using a pair of sieve sizes selected from the basic set or the basic set plus set 1 or the basic set plus set 2 in Table 1. A combination of sizes from set 1 and set 2 is not permissible. Aggregate sizes shall have D/d not less than 1,4. SIST EN 13242:2013

NOTE 2 Greater than 90 mm sieve sizes can be used for particular applications.
4.3 Grading 4.3.1 General The grading of the aggregate, when determined in accordance with EN 933-1, shall conform to the requirements of 4.3.2 to 4.3.5 as appropriate to its aggregate size d/D. Aggregates may comprise single sizes, all-in aggregates or combinations of two or more than two sizes. Aggregates supplied as a mixture of different sizes or types should be uniformly blended. When aggregates of significantly different density are blended, caution is necessary to avoid segregation. When assessing aggregates within a system of factory production control, at least 90 % of gradings, taken on different batches within a maximum period of 6 months, shall fall within the limits specified in Table 2 to Table 5 for tolerances on manufacturer declared typical gradings.

FprEN 13242:2011 (E) 4 Foreword This document (FprEN 13242:2011) has been prepared by Technical Committee CEN/TC 154 “Aggregates”, the secretariat of which is held by BSI. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 13242:2002+A1:2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Annex A is normative. Requirements for other end uses of aggregates are specified in the following European Standards: EN 12620, Aggregates for concrete; EN 13043, Aggregates for bituminous mixtures and surface treatments for roads, airfields and other trafficked areas; EN 13055 (all parts), Lightweight aggregates; EN 13139, Aggregates for mortar; EN 13383-1, Armourstone — Part 1: Specification; EN 13450, Aggregates for railway ballast. Considering evaluation of conformity see FprEN 16236, Evaluation of Conformity of aggregates. kSIST FprEN 13242:2011
FprEN 13242:2011 (E) 5 1 Scope This European Standard specifies the properties of aggregates and filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in hydraulically bound and unbound materials for civil engineering works. It also covers recycled aggregates with particle densities between 1,50 Mg/m3 (1 500 kg/m3) and 2,00 Mg/m3 (2 000 kg/m3). A list of the source materials that have been considered and are within the scope of this standard is given in Annex A (normative). This European Standard also specifies that a quality control system is in place for use in factory production control and it provides for the evaluation of conformity of the products to this European Standard. This European Standard does not cover the grading properties of unbound mixtures as specified in EN 13285.
This European Standard incorporates a general requirement that aggregates will not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination (see NOTE 3). NOTE 1 Aggregates used in hydraulically bound and unbound materials for civil engineering works should comply with all the requirements of this European Standard. The standard includes comprehensive and specific requirements for natural aggregates, iron and steel making slag and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constitution of recycled aggregates. For materials from some other secondary sources, however, work is ongoing and the requirements are incomplete. In the meantime, such materials, when placed on the market as aggregates, should conform fully to this standard but may also be required to conform to specific relevant additional requirements at the place of use. Additional characteristics and requirements may be specified on a case by case basis depending upon experience of use of the product, and defined in specific contractual documents.
NOTE 2 Requirements for lightweight aggregates are specified in EN 13055. NOTE 3 Requirements for the declaration of the potential of aggregates to release regulated dangerous substances are currently under development. Until such time as these are finalised, attention should be paid to requirements at the place of use. NOTE 4 The Tables in this standard include categories which are common across the four main aggregate standards: EN 12620, EN 13043, EN 13139 and EN 13242. Not all of these categories are appropriate for aggregates for bituminous mixtures. Only categories grey shaded are to be used for hydraulically bound and unbound materials; those in white background are not to be tested and are for information only. 2 Normative references The following referenced documents are indispensable for the application of this document.

3.2 natural aggregate aggregate from mineral sources that has been subjected to nothing more than mechanical processing 3.3 manufactured aggregate aggregate of mineral origin resulting from an industrial process involving thermal or other modification 3.4 recycled aggregate aggregate resulting from the processing of inorganic or mineral material previously used in construction 3.5 category level of a property of an aggregate expressed as a range of values or a limiting value NOTE There is no relationship between the categories of different properties. 3.6 aggregate size designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D NOTE This designation accepts the presence of some particles which are retained on the upper sieve (oversize) and some which pass the lower sieve (undersize). 3.7 grading particle size distribution expressed as the percentages by mass passing a specified set of sieves 3.8 fines particle size fraction of an aggregate that passes the 0,063 mm sieve 3.9 coarse aggregate designation given to the larger aggregate sizes with D greater than 4 mm and d greater than or equal to 1 mm NOTE Aggregates that do not fit the definitions for fine or coarse (1 mm to 3 mm or 2 mm to 4 mm) are treated as coarse aggregate. 3.10 fine aggregate designation given to the smaller aggregate sizes with D less than or equal to 4 mm and d = 0 NOTE Fine aggregates can be produced from natural disintegration of rock or gravel and/or by the crushing of rock or gravel or processing of manufactured aggregates. kSIST FprEN 13242:2011
FprEN 13242:2011 (E) 8 3.11 all-in aggregate aggregate consisting of a mixture of coarse and fine aggregates with D greater than 4 mm and d = 0 NOTE It can be produced without separating into coarse and fine fractions or it can be produced by combining coarse and fine aggregates. 3.12 filler aggregate aggregate, most of which passes a 0,063 mm sieve, which can be added to construction materials to provide certain properties 3.13 added filler filler aggregate of mineral origin, which has been produced separately 4 Geometrical requirements 4.1 General The necessity for testing and declaring all properties specified in this clause shall be limited according to the particular application at end use or origin of the aggregate. When required, the tests specified in Clause 4 shall be carried out to determine appropriate geometrical properties. NOTE 1 When the value of a property is required but not defined by specified limits the value should be declared as an XXDeclared category, e.g., a value of say 55 for the flakiness index corresponds to FI55 (Declared value) NOTE 2 When a property is not required, a “No requirement” category can be used. NOTE 3 Guidance on selection of appropriate categories for specific applications can be found in national provisions in the place of use of the aggregate. NOTE 4 Where conformity with a category is based on a value of a property being less than or equal to a given value, conformity with a more severe category (lower value) automatically confers conformity with all less severe categories (higher values). Similarly for categories based on the value of a property being greater than or equal to a given value, conformity with a more severe (higher value) automatically confers conformity with all less severe categories (lower values). 4.2 Aggregate sizes All aggregates shall be described in terms of aggregate sizes using the designations d/D, and shall comply with the grading requirements specified in 4.3, except for aggregates added as fillers which shall be specified as filler aggregate. Aggregate sizes shall be specified using a pair of sieve sizes selected from the basic set or the basic set plus set 1 or the basic set plus set 2 in Table 1. A combination of sizes from set 1 and set 2 is not permissible. Aggregate sizes shall have D/d not less than 1,4.

4.3 Grading 4.3.1 General The grading of the aggregate, when determined in accordance with EN 933-1, shall conform to the requirements of 4.3.2 to 4.3.5 as appropriate to its aggregate size d/D. Aggregates may comprise single sizes, all-in aggregates or combinations of two or more than two sizes. NOTE 1 Aggregates supplied as a mixture of different sizes or types should be uniformly blended. When aggregates of significantly different density are blended, caution is necessary to avoid segregation. When assessing aggregates within a system of factory production control, at least 90 % of gradings, taken on different batches within a maximum period of 6 months, shall fall within the limits specified in Table 2 to Table 5 for tolerances on supplier declared typical gradings. NOTE 2 Size designations and grading categories are essentially categories of convenience and different sizes and grading categories may be used by agreement between supplier and purchaser. Where the specification requires the use of sieves which are a fraction or a multiple of the upper sieve size (e.g. D/2, D/1,4 or 1,4 D, 2 D ) the sieve chosen shall be the next nearest from basic set plus set 1 or basic set plus set 2. kSIST FprEN 13242:2011
