标准摘要
[中文适用范围]： 本文件给出了骨料骨料破碎值（ACV）的测定方法。 这给出了在逐渐施加的压缩载荷下骨料破碎阻力的相对测量。 该方法适用于通过 14.0 mm 试验筛并保留在 10.0 mm 试验筛上的集料。 对于其他粒度级数，推荐的方法见附录A。 本次试验所采用的骨料粒度级数也可按相关国家标准执行。 注：相应的国家标准允许分级划分有微小变化。 该方法不适用于测试骨料破碎值高于30的骨料。 在这种情况下，适用ISO 20290-4中描述的方法。 [外文原描述]： This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve. For other size fractions, a recommended method is described in Annex A. The aggregate size fraction taken for this test can also be as per the relevant national standards. NOTE Minor variations in grading divisions can be allowed in respective national standards. The method is not suitable for testing aggregates with an aggregate crushing value higher than 30. In such cases, the method described in ISO 20290-4 is applicable.
