16、ument (EN 13285:2010) has been prepared by Technical Committee CEN/TC 227 “Road materials”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2011, and

17、 conflicting national standards shall be withdrawn at the latest by March 2011. This document supersedes EN 13285:2003. The main change compared to the previous edition is that the former informative annex classifying mixtures containing recycled aggregates has been replaced by the general reference

18、 to EN 13242. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standard

BS EN 13285:2010EN 13285:2010 (E) 5 1 Scope This European Standard specifies requirements for unbound mixtures used for construction and maintenance of roads, airfields and other trafficked areas. The requi

21、rements are defined with appropriate cross-reference to EN 13242. This European Standard applies to unbound mixtures of natural, artificial and recycled aggregates with a upper sieve size (D) from 8 mm to 90 mm and lower sieve size (d) = 0 at the point of delivery. NOTE 1 Mixtures with an upper siev

22、e size (D) greater than 90 mm are not covered by this European Standard but may be specified in the place of use. NOTE 2 Water content of the mixture and the density of the installed layer are not specified mixture requirements. Both parameters are related to the control of the construction of the l

23、ayer and are outside the scope of this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (inc

28、is document, the following terms and definitions apply. NOTE Other useful terms and definitions are given in EN 13242. 3.1 unbound mixture granular material, normally of a controlled grading with d = 0, which is generally used in pavement bases and sub-bases BS EN 13285:2010EN 13285:2010 (E) 6 NOTE

29、An unbound mixture does not contain an added binder. 3.2 category level of a property expressed as a range of values or a limiting value NOTE There is no relationship between the categories of different properties. 3.3 grading particle size distribution expressed as the percentage by mass passing a

30、specified number of sieves 3.4 batch production quantity, delivery quantity, partial delivery quantity (railway wagon-load, lorry-load, ships cargo) or stockpile produced at one specific time under conditions that are presumed to be uniform NOTE With a continuous process the quantity produced during

31、 an agreed period is treated as a batch. 4 Requirements 4.1 General requirements The need for testing for all properties in this clause shall be limited according to the particular application or end use or origin of the mixture. When required, the tests specified in 4.2 to 4.5 shall be carried out

32、to determine appropriate properties. NOTE When a test is not required, it should be specified as a “No requirement”. 4.2 Aggregate requirements When required, the following properties of the aggregates used in the mixture shall be in accordance with EN 13242: shape of coarse aggregate; percentage of

33、 crushed or broken particles and of totally rounded particles in coarse aggregates; fines quality; resistance to fragmentation of coarse aggregate; particle density; water absorption; resistance to wear of coarse aggregate; chemical requirements; durability requirements.

36、cles passing the 0,063 mm sieve shall also be greater than the values given in Table 3, according to the category chosen. Table 3 Minimum fines content Percentage passing 0,063 mm sieve by mass Category 2 LF2 4 LF4 8 LF8No requirement LFNThe categories in Table 2 and Table 3 shall be chosen so that

37、the difference between the maximum fines content and the minimum fines content is not less than 3 %.

39、re is no ISO 565/R20 series sieve size larger than 125 mm. bWhere the sieves calculated as 1,4 D and 2 D are not exact sieve numbers in the ISO 565/R20 series then the next nearest sieve size shall be adopted. When D = 90 mm the 125 mm sieve shall be used as oversize. cThe percentage passing sieve s

40、ize D may be greater than 99 % but in such cases the supplier shall declare the typical grading. d For aggregate sizes where D is smaller than 63 mm, add a range of 90 to 100 to the 1,4 D sieve. e For aggregate sizes where D is smaller than 63 mm, add a range of 85 to 100 to the 1,4 D sieve. 4.4 Gra

41、ding requirements 4.4.1 General grading curve When required, the percentage by mass passing sieve A, sieve B, sieve C, sieve E and where specified in Table 6 sieve F and sieve G determined in accordance with EN 933-1 using the sieves defined in Table 5 shall be within the overall grading range appro
