^AЦ?IO^AЁ?Ь?^И?Й? AGGREGATES FOR UNBOUND AND HYDRAULICALLY BOUND MATERIALS FOR USEIN CIVIL ENGINEERING WORK AND ROAD CONSTRUCTION
1 1 Scope
This European Standard specifies the properties of aggregates obtained by processing natural or manufactured or recycled materials for hydraulically bound and unbound materials for civil engineering work and road construction.
It provides for the evaluation of conformity of the products to this European Standard.
NOTE 1 Aggregates used in construction should comply with all the requirements of this European Standard. As well as familiar and traditional natural and manufactured aggregates Mandate M/125 "Aggregates" included recycled aggregates and some materials from new or unfamiliar sources. Recycled aggregates are included in the standards and new test methods for them are atan advanced stage of preparation. For unfamiliar materials from secondary sources, however, the work on standardisation has only started recently and more time is needed to define clearly the origins and characteristics of these materials. In the meantime such unfamiliar materials when placed on the market as aggregates must comply fully with this standard and national regulations for dangerous substances depending upon their intended 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.

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1 aggregate
granular material used in construction. Aggregate may be natural, manufactured or re-cycled
3.2 3.3 3.4 3.5 3.6 3.7 3.8 3.9 3.10 3.11 3.2 natural aggregate
aggregate from mineral sources which 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 material previously used in construction
3.5 normal weight aggregate
aggregate of mineral origin having a particle density not less than 2,00 Mg/m 3 (2000 kg/m 3 ) but less than 3,00 Mg/m 3 (3000 kg/m 3 )
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). The lower size ( d ) can be zero
3.7 fine aggregate
designation given to size aggregates with d equal to 0 and D less than or equal to 6,3 mm.
NOTE Fine aggregate can be produced from natural disintegration of rock or gravel and/or by the crushing of rock or gravel or processing of manufactured aggregate
3.8 coarse aggregate
designation given to the larger aggregate sizes with D greater than 2 mm and d greater than or equal to 1 mm
3.9 all-in aggregate
aggregate consisting of a mixture of coarse and fine aggregates with D greater than 6,3 mm NOTE It can can be produced without separatin into coarse and fine fractions or it can be produced by combining coarse and fine aggregate

particle size fraction of an aggregate which passes the 0,063 mm sieve
3.11 category
level ofa property of an aggregate expressed as a range of values or a limiting value.

4 Geometrical requirements
4.1 General
The necessity for testing and declaring all properties in this clause shall be limited according to the particular application or 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 by the manufacturer as an XX Declared category, e.g., in Table 5 a flakiness index of say 60 corresponds to FI 60 (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 When specified, the requirements for the end-use product should supersede the requirements in this European Standard (e.g., grading and/or fines content for all-in aggregates).
4.2 Aggregates 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.
Aggregate sizes shall be specified using the nominal sizes given in the Table 1 comprising the basic set or the basic set plus set 1 or the basic set plus set 2. A combination of sieve sizes from set 1 and set 2 is not allowed. size d of not less than 1,4.
Table 1 - Sieve sizes for specifying aggregate sizes
NOTE 1 Greater than 90 mm sieve sizes can be used for particular applications.
NOTE 2 Rounded sizes shown in parentheses can be used as simplified descriptions of aggregate sizes.
4.3 4.3.1 4.3 Grading
4.3.1 General
The grading of aggregate sizes when determined in accordance with EN 933-1 shall comply with the requirements of 4.3.2 and 4.3.3 as appropriate to its aggregate size d / D .
Combinations of two or more than two adjacent aggregate sizes or all-in aggregates are permitted.
NOTE Aggregate 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 production 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 4.3.2 and 4.3.3 for tolerances on manufacturers’ declared ty
