5.3 Water Water shall not contain components which adversely affect the hardening and the performance of the cement bound granular mixtures. 5.4 Retarders Retarders shall comply with provisions valid in the place of use. 6 Cement bound granular mixture 6.1 Types 6.1.1 General Cement bound granular mixtures shall be made from the constituents specified in Clause 5. The mixture shall be selected from the five types described in 6.1.2, 6.1.3, 6.1.4, 6.1.5 and 6.1.6, and shall conform to the specified requirements for the selected mixture. 6.1.2 Cement bound granular mixture 1 Cement bound granular mixture 1 shall be either a 0/31,5 mm, a 0/20 mm or a 0/14 mm mixture with a grading, determined in accordance with EN 933-1, complying with the corresponding requirements of Figures 1, 2 and 3 using either G1 or G2 limits.
6.1.3 Cement bound granular mixture 2 6.1.3.1 Description Cement bound granular mixture 2 shall be a granular mixture with compacity requirement. There are three options depending on the aggregate size. 6.1.3.2 Grading of the mixture The grading of the selected option, determined in accordance with EN 933-1, shall comply with Table 1. Either category G1 or category G2 of the grading envelopes and Figures 4 to 6 shall be specified. SIST EN 14227-1:2013

6.1.4 Cement bound granular mixture 3 6.1.4.1 Description Cement bound granular mixture 3 shall be a granular mixture with a maximum nominal size of D equal to or less than 6,3 mm with an immediate bearing index requirement. 6.1.4.2 Grading of the mixture The grading of the mixture, determined in accordance with EN 933-1, shall comply with Table 2. Table 2 — Grading of cement bound granular mixture 3 Column 1 2 3 4 Line Sieve mm 2D D 0,063 1 Percentage of the mixture passing by mass 100 ≥85 ≤35
6.1.4.3 Immediate bearing index The immediate bearing index category shall be selected from Table 4. 6.1.5 Cement bound granular mixture 4 Cement bound granular mixture 4 shall be a mixture where the grading, including declared upper and lower limits, determined in accordance with EN 933-1, is declared by the supplier. When required, an immediate bearing index category selected from Table 4 shall be declared. 6.1.6 Cement bound granular mixture 5 Cement bound granular mixture 5 shall be a mixture where the grading, determined in accordance with EN 933-1, complies with the limits in Table 3. SIST EN 14227-1:2013

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. Irrespective of the binder content necessary to fulfil the strength requirements of this European 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 cement 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
