When required, an immediate bearing index category selected from Table 3 shall be declared. 6.2 Water content of mixtures The water content shall be selected to permit compaction on site by rolling and to optimise the mechanical performance of the mixture. The water content shall be determined by the Proctor test or other method in accordance with EN 13286-1, EN 13286-2, EN 13286-3, EN 13286-4 and EN 13286-5, and limits set to give a workable range of water content on site compatible with the compaction and the desired mechanical performance of the mixture. 6.3 Proportioning of the constituents, grading and dry density The proportioning of the constituents, expressed as a percentage by dry mass of the total dry mass of the mixture, the grading, and the dry density of the mixture shall be declared. The declared proportions shall be based on the laboratory mixture design and/or practical experiences with mixtures produced with the same constituents and under the same conditions in a way that the mixture complies with the requirements of this European Standard.

EN 14227-5:2013 (E) 10 Irrespective of the binder content necessary to fulfil the strength requirements of this standard, the binder content should normally not be less than a minimum value fixed by provisions valid at the place of use to ensure adequate distribution of the binder throughout the mixture. 6.4 Other requirements for the fresh mixture 6.4.1 Compacity The minimum compacity of hydraulic road binder bound granular mixture 2 at the maximum modified Proctor dry density shall be 0,80 calculated in accordance with Annex A (normative). 6.4.2 Immediate bearing index of the mixture In order to facilitate site compaction and depending on trafficking, the immediate bearing index of the mixture, determined in accordance with EN 13286-47 using modified Proctor compaction: shall not be less than 50 for hydraulic road binder bound granular mixture 2 – 0/10; shall be selected from Table 3 for hydraulic road binder bound granular mixture 3 and, when required, mixture 4.

Mixtures with an immediate bearing index less than 40 may not support immediate trafficking and should be used with care. The addition of another aggregate can be necessary to achieve the immediate bearing index required for immediate use. 6.4.3 Workability period When required for the intended use and the weather conditions, the workability period, determined in accordance with EN 13286-45, shall be declared. 7 Laboratory mechanical performance classification 7.1 General Laboratory mechanical performance shall be characterised and classified by one of the following methods: compressive strength Rc; the combination Rt, E of tensile strength Rt and modulus of elasticity E. NOTE No correlation is intended nor can be assumed between the two methods. SIST EN 14227-5:2013
EN 14227-5:2013 (E) 11 7.2 Classification by compressive strength Mixtures shall be classified by compressive strength determined in accordance with EN 13286-41, carried out on specimens manufactured in accordance with EN 13286-50, EN 13286-51, EN 13286-52 and EN 13286-53. The class of compressive strength shall be selected from Table 4 in combination with the selected method of specimen manufacture. NOTE The permitted methods of specimen manufacture realise different specimen shapes and density, and thus for the same mixture, different strengths. Hence, it is important, on the basis of experience and utilisation, not to separate strength from the method of specimen manufacture. The age of classification and curing conditions shall be specified in accordance with practice at the place of use. For characterisation or mixture design testing in the laboratory, compressive strength 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 other values.
