It has been recognized that improper compaction (or void content) is the most significant factor affecting mix performance An increase in void content leads to a decrease in modules fatigue life and resistance to permanent deformation These reduced factors equate to a great reduction in pavement life A decrease in void content beyond an optimum range leads to flushing and reduced skid resistance As such all finished hot-mix asphalt pavements which do not conform to the specified relative compaction requirements will be paid for using the following pay factors
