aggregate toughness abrasion resistance and durability in indonesia

Toughness and Abrasion Resistance Aggregates undergo substantial wear and tear throughout their life In general they should be hard and tough enough to resist crushing degradation and disintegration from any associated activities including manufacturing stockpiling production placing compaction in the case of HMA and consolidation in the case of PCC Roberts et al 1996 1
