QC and agency inspection, sampling, and testing facilities. It is crucial to understand the relationship of plant layout and circuitry. More movements mean increased costs, larger potential for segregation of the aggregates, potential safety problems, material contamination and
the same as those used in the mix design. The factor that primarily controls the optimum asphalt content is the air voids in laboratory compacted samples. This should be controlled near 4%. The asphalt cement content should be checked at the plant by testing loose mix (we typically use solvent extraction or ignition
