This Europ
21、ean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2018, and conflicting national standards shall be withdrawn at the latest by March 2020. Attention is drawn to the possibility that some of the eleme
22、nts of this document may be the subject of patent rights. CEN not be held responsible for identifying any or all such patent rights. This document supersedes EN 13285:2010. Compared with EN 13285:2010 the following changes have been made: a) Introduction of new categories for mixtures, designations,
23、 grading and fines content; b) adjustment of scope for new categories to an upper sieve size (D) range from 5,6 mm to 90 mm; c) introduction of definitions for new terms; d) A-Deviation by Estonia introduced in new Annex C. The former Annex C is now part of Clause 5. According to the CEN/CENELEC Int
24、ernal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland,
25、Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 13285:2018EN 13285:2018 (E) 4 1 Scope This European Standard specifies requirements for unbound mixtures
26、used for construction and maintenance of roads, airfields and other trafficked areas. This European Standard applies to unbound mixtures of natural, manufactured and recycled aggregates with an upper sieve size (D) from 5,6 mm to 90 mm and lower sieve size (d) = 0 at the point of delivery. NOTE 1 Mi
27、xtures with an upper sieve 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
28、the construction of the layer and are outside the scope of this European Standard. The aggregate requirements are defined with appropriate cross-reference to EN 13242. Use of aggregates as soil is not covered by this standard. 2 Normative references The following documents, in whole or in part, are
29、normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies EN 932-1, Tests for general properties of aggregates Part

35、rolled grading with d = 0, which is generally used in pavement bases and sub-bases and surface layers Note 1 to entry: An unbound mixture does not contain an added binder. 3.2 manufacturers declared value (MDV) value declared by the manufacturer accompanied by a declared tolerance 3.3 week of produc
36、tion 5 days of production in a period no longer than 3 months 3.4 month of production 20 days of production in a period no longer than 6 months 3.5 six month of production 120 days of production in a period no longer than 2 years 3.6 year of production at least one day of production in a period no l
37、onger than 12 months Note 1 to entry: For the purpose of the test frequencies, a year of production is the same as a calendar year. 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 or
38、igin of the mixture. When required, the tests specified in 4.2 to 4.3 shall be carried out to determine appropriate properties. When a test is not required, it should be specified as a “No requirement”. 4.2 Aggregate requirements The following properties of the aggregates used in the mixture shall b
39、e in accordance with EN 13242: shape of coarse aggregate; percentage of crushed particles and of totally rounded particles in coarse aggregates; fines quality; resistance to fragmentation of coarse aggregate; BS EN 13285:2018EN 13285:2018 (E) 6 particle density; water absorption; resistance to wear
40、of coarse aggregate; chemical requirements (e.g. water soluble sulphate); classification of the constituents of recycled aggregates; durability requirements. 4.3 Mixture requirements 4.3.1 Mixture designation Mixtures (0/D) shall be selected from Table 1. Table 1 Mixture designation 0/5,6 (0/5) 0/6,
41、3 (0/6) 0/8 0/10 0/11,2 (0/11) 0/12,5 (0/12) 0/14 0/16 0/20 0/22,4 (0/22) 0/31,5 (0/32) 0/40 0/45 0/56 0/63 0/80 0/90 NOTE Rounded sizes shown in parentheses can be used as simplified descriptions of aggregate sizes. Other mixture designations 0/D may be declared with D selected from the ISO 565/R20
42、 series. 4.3.2 Fines content When required, the percentage of particles which pass the 0,063 mm sieve (fines) determined in accordance with EN 933-1 shall not exceed the values in Table 2, according to the category chosen.

47、requirements related to the 1,4 D sieve apply because there 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 s
48、hall be used as oversize. cThe percentage passing sieve size D may be greater than 99 % but in such cases the manufacturer shall declare the typical grading. dFor unbound mixtures where D is smaller than 63 mm. 4.3.4 Grading requirements 4.3.4.1 General grading curve The percentage by mass passing,
49、when determined in accordance with EN 933-1, shall conform to the category selected from Table 5. The appropriate sieves shall be selected from Table 6.
