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]).

When crushing and screening is carried out in proximity to the demolition/removal site, hauling costs come down substantially. Mobile recycling plants are capable of crushing and separating bitumen and aggregates for the ease of using again afterwards. They can crush asphalt in different sizes to serve different purposes.
