EN 13108-1:2006 (E) 5 Introduction The ultimate aim is to specify Asphalt Concrete in terms of fundamental, performance based properties. However given the differences in knowledge and experience with fundamental specifications for this mix type in Europe, it is not possible to choose only the fundamental approach. This European Standard therefore provides two ways of specifying Asphalt Concrete:  The first, or empirical approach specifies Asphalt Concrete in terms of compositional recipes and

requirements for constituent materials with additional requirements based on performance related tests. These requirements are in 5.2 and 5.3.  The second, or fundamental approach specifies Asphalt Concrete in terms of performance-based requirements linked to limited prescription of composition and constituent materials, offering a greater degree of freedom. These requirements can be found in 5.2 and 5.4. It is envisaged that, as users gain experience with performance based testing, there will be a shift towards greater use of the fundamental approach to specification. Asphalt Concrete is used for surface courses, binder courses regulating courses, and bases.

EN 13108-1:2006 (E) 6 1 Scope This European Standard specifies requirements for mixtures of the mix group Asphalt Concrete for use on roads, airfields and other trafficked areas. NOTE A mixture specification derived from this Standard can be used either to declare the conformity of a mixture with known requirements or to make known what those requirements are. This European Standard includes requirements for the selection of the constituent materials. It is designed to be read in conjunction with EN 13108-20 and EN 13108-21. Asphalt Concrete mixtures with chemical modified binders not covered by EN 14023 are not covered by this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

A course may be laid in one or more layers 3.1.4 surface course upper course of the pavement, which is in contact with the traffic 3.1.5 binder course part of the pavement between the surface course and the base 3.1.6 regulating course course of variable thickness applied to an existing course or surface to provide the necessary profile for a further course of consistent thickness 3.1.7 base main structural element of a pavement. The base may be laid in one or more courses, described as “upper” base, “lower” base etc. 3.1.8 Asphalt Concrete asphalt in which the aggregate particles are continuously graded or gap-graded to form an interlocking structure 3.1.9 mix formulation composition of a single mixture expressed as a target composition NOTE A target composition may be expressed in two ways (see 3.1.10 and 3.1.11). 3.1.10 input target composition expression of a mix formulation in terms of the constituent materials, the grading curve and the percentage of bitumen added to the mixture NOTE This will usually be the result of a laboratory mix design and validation.

EN 13108-1:2006 (E) 8 3.1.11 output target composition expression of a mix formulation in terms of the constituent materials and the mid point grading and soluble binder content to be found on analysis NOTE This will usually be the result of a production validation. 3.1.12 additive constituent material, which can be added in small quantities to the mixture, e.g. inorganic or organic fibres or polymers, to influence the mechanical properties, the workability or the colour of the mixture 3.1.13 performance-based requirement requirement for a fundamental engineering property (e.g. stiffness, fatigue properties) that predicts performance and appears in primary performance prediction relationships 3.1.14 performance-related requirement requirement for a characteristic (e.g. wheel tracking properties, Marshall properties) that has been found to correlate with a fundamental engineering property that predicts performance 3.1.15 empirical specification combination of requirements for composition and constituent materials together with performance-related requirements 3.1.16 fundamental specification combination of performance-based requirements together with limited requirements for composition and constituent materials, with more degrees of freedom than for an empirical specification NOTE In practice some characteristics will be performance-related. 3.2 Symbols and abbreviations AC Asphalt Concrete D upper sieve size of the aggregate in the mixture, in millimetres (mm) 4 Requirements for constituent materials 4.1 General Only constituent materials with established suitability shall be used. The establishment of suitability shall result from one or more of the following:  European Standard;  European Technical Approval;  specifications for materials based on a demonstrable history of satisfactory use in asphalt. Evidence shall be provided on their suitability. This evidence may be based on research combined with evidence from practice.

EN 13108-1:2006 (E) 9 NOTE In the European asphalt industry it is common practice to use additives like inorganic or organic fibres, pigments, waxes etc., which are not covered by a European Standard or ETA. This European Standard allows the use of those materials. 4.2 Binder 4.2.1 General The binder for empirically and fundamentally specified mixtures shall be paving grade bitumen, modified bitumen or hard grade bitumen. The paving grade bitumen shall conform to EN 12591, the modified bitumen to EN 14023 and the hard grade bitumen to prEN 13924. The binder in empirically specified mixtures shall conform to 4.2.2. Natural asphalt conforming to EN 13108-4:2005, Annex B, may be added. 4.2.2 Binder in empirically specified mixtures 4.2.2.1 Selection of binder The grade of the bitumen, the type and grade of modified bitumen and the amount and category of natural asphalt shall be as specified. In case of a paving grade bitumen the grade shall be selected from the grades between 20/30 and 330/430 inclusively and in case of a hard grade bitumen the grade shall be selected from the grades 10/20 and 15/25. NOTE 1 Given the wide variety of climates, traffic loads, used materials etc. it can be necessary to select on a regional level specific binders. When modified bitumen is used to improve properties that are not covered by the empirical specification additional proof shall be provided. This proof shall be delivered through investigation using standards in the EN 12697 series, that the modified bitumen is suitable for improving the desired functional characteristics. The proof may be based on earlier research. NOTE 2 EN 14023 is a grading system and is only meant to characterise the modified bitumen. The modified bitumen specifications are not functionally based, and it is not possible to combine these specifications with empirical asphalt specifications to demonstrate functional behaviour. The proof required would normally be a Type Testing on a similar mixture incorporating the modified binder showing fulfilment of the relevant property. The grade of the bitumen, the type and grade of the modified bitumen, the grade of the hard grade bitumen and the amount and category of natural asphalt may be selected. 4.2.2.2 Surface courses with reclaimed asphalt When using more than 10 % by mass of the total mixture of reclaimed asphalt from mixtures in which only paving grade bitumen has been used and when the binder added to the mixture is a paving grade bitumen and the grade of the bitumen is selected, the binder shall conform to the following requirement:  Penetration or the softening point of the binder in the resulting mixture, calculated from the penetrations or the softening points of the added binder and the recovered binder from the reclaimed asphalt, shall meet the penetration or softening point requirements of the selected grade. The calculation shall be executed according to Annex A. Either the penetration or the softening point requirement shall be selected. 4.2.2.3 Regulating courses, binder courses and bases with reclaimed asphalt When using more than 20 % by mass of the total mixture of reclaimed asphalt from mixtures in which only paving grade bitumen has been used and when the binder added to the mixture is a paving grade bitumen and the grade of the bitumen is selected, the binder shall conform to the following requirement:

EN 13108-1:2006 (E) 10  Penetration or the softening point of the binder in the resulting mixture, calculated from the penetrations or the softening points of the added binder and the recovered binder from the reclaimed asphalt, shall meet the penetration or softening point requirements of the selected grade. The calculation shall be executed according to Annex A. Either the penetration or the softening point requirement shall be selected. 4.3 Aggregates 4.3.1 Coarse aggregate Coarse aggregate shall conform to EN 13043 as appropriate for the intended use. 4.3.2 Fine aggregate Fine aggregate shall conform to EN 13043 as appropriate for the intended use. For fundamentally specified mixtures the angularity shall not be selected. 4.3.3 All-in aggregates All-in aggregate shall conform to EN 13043 as appropriate for the intended use. 4.3.4 Added filler Filler aggregate shall conform to EN 13043 as appropriate for the intended use. The amount of added filler shall be as specified. For fundamentally specified mixtures, the stiffening properties shall not be selected. NOTE 1 Filler includes materials as cement and hydrated lime. NOTE 2 The expression “as appropriate for the intended use” in 4.3.1 to 4.3.4 means that the selection of the requirements and the particular category depends on a number of conditions. These conditions will include traffic density, climatic conditions, the construction of the course in which the mixture will be used, and economic considerations. 4.4 Reclaimed asphalt The use and the amount of reclaimed asphalt, and the mix group from which the reclaimed asphalt has been or will be derived shall be as specified. The properties of reclaimed asphalt declared in accordance with EN 13108-8 shall conform to specified requirements appropriate to the intended use. NOTE The expression “appropriate to the intended use” means that the selection of the requirements and the particular category depends on a number of conditions. These conditions will include traffic density, climatic conditions, the construction of the course in which the mixture will be used, and economic considerations. The upper sieve size D of the aggregate in the reclaimed asphalt shall not exceed the upper sieve size D of the mixture. The aggregate properties of the reclaimed asphalt shall fulfil the requirements specified for the aggregate for the mixture. 4.5 Additives The nature and properties of all additives shall be declared and they shall conform to the specifications required in 4.1.

EN 13108-1:2006 (E) 11 5 Requirements for the mixture 5.1 Empirical or fundamental requirements 5.1.1 Declaration of the target composition The mix formulation shall be declared and documented. 5.1.2 Empirical requirements At the target composition the mixture shall fulfil general requirements plus empirical requirements selected from 5.2 and 5.3. 5.1.3 Fundamental requirements At the target composition the mixture shall fulfil general requirements plus fundamental requirements selected from 5.2 and 5.4. 5.2 General requirements 5.2.1 Composition and grading 5.2.1.1 Composition The grading shall be expressed in percentages by mass of total aggregate.

NACIONALNI PREDGOVOR

Evropski standard EN 13108-1:2006 je pripravil tehnični odbor Evropskega komiteja za

standardizacijo CEN/TC 227 Materiali za ceste. Slovenski standard SIST EN 13108-1:2006 je prevod

evropskega standarda EN 13108-1:2006. V primeru spora glede besedila slovenskega prevoda v tem

standardu je odločilen izvirni evropski standard v enem od treh uradnih jezikov CEN. Slovensko izdajo

standarda je pripravil tehnični odbor SIST/TC CES Ceste.

Odločitev za izdajo tega standarda je dne 7. junija 2006 sprejel SIST/TC CES Ceste.

SIST EN 13108-1 : 2006
Uvod

Končni cilj je določiti zahteve za bitumenski beton na podlagi temeljnih, na obnašanju temelječih

lastnosti. Vendar, ker se sedanje znanje in izkušnje s temeljnimi lastnostmi za to vrsto asfaltnih zmesi

v Evropi razlikujejo, ni mogoče uporabiti samo temeljnega pristopa.
Ta standard zato določa dva načina podajanja lastnosti bitumenskega betona:

– prvi, izkustveni pristop določa bitumenski beton na podlagi obstoječih receptur, kombiniranih z

zahtevami za sestavne materiale in z dodatnimi zahtevami, ki temeljijo na izvajanju preskusov,

povezanih z obnašanjem. Te zahteve so v točkah 5.2 in 5.3;

– drugi, temeljni pristop določa bitumenski beton na podlagi zahtev, temelječih na obnašanju, v

povezavi z omejeno predpisano sestavo zmesi in sestavnih materialov, kar omogoča večjo

možnost izbire. Te zahteve so v točkah 5.2 in 5.4.

Načrtovano je, da bodo uporabniki potem, ko bodo pridobili dovolj izkušenj s preskušanjem,

temelječem na obnašanju, bolj težili k večji uporabi temeljnega načina pri določanju bitumenskih

betonov.

Bitumenski beton se uporablja za obrabne plasti, vezne in izravnalne plasti ter nosilne plasti.

1 Področje uporabe

Ta evropski standard določa zahteve za skupino zmesi bitumenskih betonov za uporabo na cestah,

letališčih in drugih prometnih površinah.

OPOMBA: Določila za zmesi, ki izhajajo iz tega evropskega standarda, se lahko upoštevajo pri oblikovanju izjave o

skladnosti zmesi s poznanimi zahtevami ali pa samo za obveščanje o teh zahtevah.

Ta evropski standard vključuje zahteve za izbiro sestavnih materialov. Zasnovan je tako, da se

uporablja skupaj s standardoma EN 13108-20 in EN 13108-21.

Zmesi bitumenskih betonov s kemično modificiranimi vezivi, ki niso predmet standarda EN 14023, niso

predmet tega evropskega standarda.

4 Zahteve za sestavne materiale
4.1 Splošno
Uporabljati je treba samo sestavne materiale z ugotovljeno ustreznostjo.
Ustreznost je treba ugotoviti na podlagi enega ali več naslednjih dokumentov:
– evropskega standarda,
– evropskega tehničnega soglasja,

– določil za materiale, ki temeljijo na dokazljivi zgodovini zadovoljive uporabe v proizvodnji asfaltnih

zmesi v preteklosti. Ustreznost materialov mora biti dokazana. Dokazi so lahko osnovani na

raziskavah, združenih z dokazi iz prakse.

OPOMBA: V evropski asfaltni proizvodnji je običajna praksa uporaba dodatkov, kot so anorganska ali organska vlakna,

barvila, voski itd., ki jih evropski standardi ali evropska tehnična soglasja ne obravnavajo. Ta evropski standard

dopušča uporabo teh materialov.
4.2 Vezivo
4.2.1 Splošno

Kot vezivo za izkustveno in temeljno določene asfaltne zmesi je treba uporabljati cestogradbeni

bitumen, modificirani bitumen ali trši bitumen. Cestogradbeni bitumen mora biti skladen s standardom

EN 12591, modificirani bitumen s standardom EN 14023 in trši bitumen s standardom EN 13924.

---------------------- Page: 12 ----------------------
SIST EN 13108-1 : 2006
Vezivo v izkustveno določenih zmeseh mora biti skladno s točko 4.2.2.
Dodaja se lahko naravni asfalt, skladen s standardom EN 13108-4:2005, dodatek B.
4.2.2 Vezivo v izkustveno določenih zmeseh
4.2.2.1 Izbor veziva

Vrsta bitumna, tip in vrsta modificiranega bitumna ter količina in kategorija naravnega asfalta morajo

biti, kot so določeni. Cestogradbeni bitumen je treba izbrati med vrstami 20/30 in vključno 330/430, trši

bitumen pa med vrstama 10/20 in 15/25.

OPOMBA 1: Pri izbiri veziv v posameznih regijah je morda treba upoštevati raznolikost podnebja, prometnih obremenitev,

uporabljenih materialov itd.

Če se za izboljšanje lastnosti, ki niso obravnavane z izkustvenimi določili, uporabi modificirani

bitumen, je treba zagotoviti dodatne dokaze. Takšen dokaz mora temeljiti na preskusih po standardih

skupine EN 12697, ki potrdijo, da je modificirani bitumen primeren za izboljšavo želenih funkcionalnih

lastnosti. Dokaz lahko temelji na predhodnem raziskovanju.

OPOMBA 2: Sistem razvrščanja v standardu EN 14023 je namenjen samo za okarakterizacijo modificiranega bitumna.

Določila za modificirani bitumen niso funkcionalno osnovana in jih ni mogoče kombinirati z izkustvenimi določili

za asfaltne zmesi za predstavitev funkcionalnega obnašanja. Zahtevani dokaz bi bil ponavadi tipski preskus

podobne zmesi, ki vsebuje modificirani bitumen, s prikazom izpolnjevanja relevantne lastnosti. Vrsto bitumna,

tip in vrsto modificiranega bitumna ter količino in kategorijo naravnega asfalta je mogoče izbrati.

4.2.2.2 Obrabne plasti s ponovno uporabljenim asfaltom

Če je v masi celotne zmesi več kot 10 % mase ponovno uporabljenega asfalta vzetih iz zmesi, v

katerih je bil uporabljen samo cestogradbeni bitumen, in če je kot vezivo dodana zmesi določena vrsta

cestogradbenega bitumna, mora vezivo ustrezati naslednji zahtevi:

– penetracija ali točka zmehčišča veziva v dobljeni zmesi, izračunani iz penetracije ali točke zmehčišča

dodanega veziva in veziva iz ponovno uporabljenega asfalta, mora izpolnjevati zahteve za penetracijo
