31、egulations, 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, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg,

BS EN 13286-2:2010EN 13286-2:2010 (E) 5 1 Scope This European Standard specifies test methods for the determination of the relationship between the water content and the dry

33、 density of hydraulically bound or unbound mixtures after compaction under specified test conditions using Proctor compaction. It allows an estimate of the mixture density that can be achieved on construction sites and provides a reference parameter for assessing the density of the compacted layer o

34、f the mixture. This European Standard applies only to unbound and hydraulically bound mixtures of aggregates used in road construction and civil engineering work. It is not applicable to soils for earthworks. The results of this test method can be used as a basis for comparing mixtures before use in

35、 road construction. The test results also allow a conclusion to be drawn as to the water content at which mixtures can be satisfactorily compacted in order to achieve a given dry density. This test is suitable for mixtures with different values of upper sieve (D) size up to 63 mm and an oversize up

36、to 25 % by mass. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

43、oratory reference dry density of the self-draining mixture 4 Principle Six similar compaction tests are described, each with procedural variations related to the maximum particle size of the mixture to be investigated, the required quantity of sample and the size of the mould. In the Proctor test a

44、2,5 kg rammer is used. In the modified Proctor test a much greater degree of compaction is added by using different rammers (4,5 kg or 15 kg) and/or greater drops on thinner layer of material as in the Proctor test. The size of the compaction mould is chosen in relation to the value of D. If oversiz

45、e particles are present equivalent tests are carried out in larger moulds. If more than 25 % of material is retained on a 63 mm test sieve, the test method is not suitable. 5 Apparatus 5.1 Cylindrical test moulds, fitted with a removable extension not less than 50 mm high and a detachable steel base

46、 plate as shown in Figure 1. The mould shall have a smooth finish on inside face. The dimensions of moulds (Proctor mould (A), large Proctor mould (B) and extra large Proctor mould (C) shall be as given in Table 1. The diameter of the mould shall be at least four times of D of the mixture. Table 1 D
