EN 14227-10:2006 (E) 7 5.2 Binder Binder shall consist of one of the following: a) cement conforming to EN 197-1; b) cement conforming to EN 197-4. NOTE Cement conforming to EN 197-1, grades CEM II to CEM V or EN 197-4 might have setting rates, which vary significantly from those for the CEM 1 grades of EN 197-1. This will need to be considered when selecting the fresh and mechanical performance criteria and testing regimes. 5.3 Soil Not less than 95 % of the soil shall pass the 63 mm sieve when tested using the wet sieving method conforming to EN 933-1. Where applicable, the soil shall conform to the requirements for classification and homogeneity valid in the place of use.

EN 14227-10:2006 (E) 8 7 Requirements of the fresh mixture 7.1 Water content The water content shall be selected to permit compaction on site by rolling and to optimize the mechanical performance of the mixture. The optimum water content shall be determined by a selected test method in accordance with EN 13286-1 to EN 13286-5. In addition the range of water content shall be adhered to that is compatible with the compaction performance and the desired mechanical performance of the mixture. The water content of the mixture shall conform to one of the categories in Table 1. Table 1 — Minimum water content Minimum water content Category No requirement WNR Not less than 0,90 optimum water content of the mixture determined in accordance with the selected method of compaction from EN 13286-2 to EN 13286-5 W0,90 Not less than 0,95 optimum water content of the mixture determined in accordance with the selected method of compaction from EN 13286-2 to EN 13286-5 W0,95 Not less than the optimum water content of the mixture determined in accordance with the selected method of compaction from EN 13286-2 to 13286-5 W1,0 Declared value WDV 7.2 Degree of pulverization The degree of pulverization of the mixture shall be determined in accordance with EN 13286-48 and shall conform to one of the categories selected from Table 2.

8 Laboratory mechanical performance classification 8.1 General The laboratory mechanical performance of the mixture shall be characterized and classified by one of the following methods:  for cement stabilized soils, by California bearing ratio (CBR);  for cement bound soils by compressive strength Rc; or by the combination Rt, E of tensile strength Rt and modulus of elasticity E. NOTE No correlation is intended nor should be assumed between the methods of characterization.



EN 14227-10:2006 (E) 10 8.2 California bearing ratio of cement stabilized soil The CBR class shall be selected from Table 5. The CBR value shall be measured in accordance with EN 13286-47, with the following modifications and additions: a) CBR specimens shall be stored at (20 ± 2) °C; b) specimens shall initially be cured out of water, with any change in water content not exceeding 0,5 % and, when required, for a secondary period in a soaked condition; c) duration of the initial and secondary curing periods shall be selected from Table A.1. Table 5 — California bearing ratio CBR requirements Class No requirement CBRNR ≥ 15 CBR15 ≥ 20 CBR20 ≥ 30 CBR30 ≥ 40 CBR40 ≥ 50 CBR50 ≥ 60 CBR60 ≥ 70 CBR70 ≥ 80 CBR80 Declared value CBRDV 8.3 Classification of cement bound soil 8.3.1 General The mechanical performance of cement bound soil shall be determined in accordance with EN 13286-40 to EN 13286-43, depending on whether the compressive strength Rc or a combination of tensile strength Rt and modulus of elasticity E is to be determined. Testing shall be carried out on moulded cubic or cylindrical test specimens conforming to EN 13286-50, EN 13286-51, EN 13286-52 or EN 13286-53. NOTE 1 The systems of classification by compressive strength or by tensile strength with elastic modulus are mutually independent and no equivalence is intended between the strength classes of the two systems. Cubic specimens shall have a nominal size of 100 mm or 150 mm. The nominal diameter of cylindrical specimens shall be 100 mm, 150 mm or 160 mm. Cylinder moulds with a nominal diameter of 100 mm or 100 mm cube moulds shall only be used for mixtures with an upper sieve size D not exceeding 22,4 mm. The slenderness ratio shall conform to the limits in Table 6. NOTE 2 The permitted methods of specimen manufacture produce different specimen density and aggregate packing. Thus for the same mixture, different strengths are obtained when the specimen manufacturing method is varied. The curing regime used in storing specimens prior to test will also influence the strength and modulus test results. Hence it is important, not to separate strength, or strength and modulus of elasticity, requirements from the method of specimen manufacture and curing.



EN 14227-10:2006 (E) 11 8.3.2 Classification by compressive strength The class of compressive strength shall be selected from Table 6 in combination with the selected method of specimen manufacture in accordance with EN 13286-50, EN 13286-51, EN 13286-52 or EN 13286-53 and tested in accordance with EN 13286-41. The curing period for the test specimens prior to compressive strength testing being carried out shall be selected from Table A.2. For characterization or mixture design testing in the laboratory Rc shall be the average result from three specimens. If one value varies by more than 20 % of the average, it shall be discarded and Rc taken as the average of the two remaining values. Table 6 —Compressive strength classification Minimum Rc in MPa for cylinders of slenderness ratio 2 Minimum Rc in MPa for cylinders of slenderness ratio 1 a and cubes Rc Class No requirement No requirement CNR 0,4 0,5 C0,4/0,5 0,8 1 C0,8/1 1,5 2 C1,5/2 3 4 C3/4 5 6 C5/6 8 10 C8/10 12 15 C12/15 16 20 C16/20 Declared value Declared value CDV a Includes cylinder specimens with slenderness ratio of 0,8 to 1,2. Where specimens with slenderness ratio greater than 1,2 are to be used a correlation with cylinders with a slenderness ratio of 1 or 2 (whichever is the closer to the specimen slenderness ratio) shall be established. 8.3.3 Classification by Rt, E 8.3.3.1 General The class of Rt, E shall be selected from Figure 1. The curing period for the test specimens prior to tensile strength testing and the determination of the modulus of elasticity shall be selected from Table A.2. For characterization or mixture design testing in the laboratory, Rt and E shall be the average result from at least three specimens. If one value varies by more than 20 % of the average, it shall be discarded and Rt and E taken as the average of the two remaining values. Rt and E shall be established using one of the equivalent methods outlined in 8.3.3.2 to 8.3.3.4. 8.3.3.2 Method by direct tensile testing Rt shall be determined in accordance with EN 13286-40.



EN 14227-10:2006 (E) 12 E shall be determined in direct tension Et in accordance with EN 13286-43. For both determinations, specimens shall be manufactured using vibrocompression in accordance with EN 13286-52. 8.3.3.3 Method by indirect tensile testing Rt shall be derived from Rit determined in accordance with EN 13286-42 using the relationship Rt = 0,8 Rit. Test specimens shall be made in accordance with EN 13286-50, EN 13286-51, EN 13286-52 or EN 13286-53 and tested in accordance with EN 13286-41. E shall be derived from Eit (E measured in indirect tension) determined in accordance with EN 13286-43 using the relationship E = Eit. Test specimens shall be made using the same method as that used for the specimens to be tested for indirect tensile testing. 8.3.3.4 Method by indirect tensile and compression testing Rt shall be derived from Rit determined in conformity to EN 13286-42 using the relationship Rt = 0,8 Rit. E shall be derived from Ec (E measured in compression) determined in conformity to EN 13286-43 using the relationship E = Ec.
