本标准描述了用于型式试验的参考方法，并且在争议的情况下，通过Rigden装置确定干式压实填料的空隙。为了其他目的，特别是工厂生产控制，可以使用其他方法，条件是与参考方法建立适当的工作关系。该测试适用于天然和制造的填料。例如用于确定它们的沥青承载能力

This standard describes the reference method used for type testing and in cases of dispute, the determination of the voids of dry compacted filler by means of a Rigden apparatus. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established. The test is applicable to natural and manufactured fillers. It is used, for example to determine their bitumen carrying capacity.
