Phạm vi áp dụng / Scope of standard

This document describes a procedure for calculating volumetric characteristics of a compacted bituminous specimen: the air voids content (Va), the voids content in the mineral aggregate filled with binder (VFB) and the voids content in the mineral aggregate filled with binder and additives (VFBad) for the case of mixtures containing additives in their composition

The method is suitable for specimens which are laboratory compacted or specimens cut from the pavement after placement and compacting or from laboratory compacted slabs, either by coring or sawing

These volumetric characteristics can be used as mix design criteria or as parameters for evaluating the mixture after placing and compacting in the road
