Effect of Filler and Binder Contents on Air Voids in Hot-Mix
This is an alternative method, based on the extended Marshall compaction procedure used in the PRD test [24], which uses a vibrating hammer for compaction. Mixtures were prepared and subjected to a 2-minute vibration on each face, using a vibrating hammer as a means of refusal compaction to determine retained air voids.
