BS EN 12697-8:2018 PDF Download

BS EN 12697-8:2018 standard outlines the procedure for determining the void characteristics of compacted bituminous specimens. Specifically, it covers the calculation of 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). This method can be applied to specimens that are laboratory compacted or obtained from the pavement through coring or sawing techniques.

The standard emphasizes that the calculated volumetric characteristics are important for both mix design and post-compaction evaluation of bituminous mixtures in road construction. By assessing the void characteristics, engineers and practitioners can make informed decisions about the composition and performance of bituminous mixtures. Furthermore, this standard provides a standardized approach to ensure consistency and reliability in determining these void characteristics, thereby facilitating comparisons across different mixtures and projects.
