their disintegration due to impact. This characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. 3.

combined asphaltaggregate mixture which are determined through laboratory testing. Significant variability can be associated with these tests as noted in AASHTO and ASTM precision statements. A review of the precision statements associated with HMA mix design was performed and recommendations were made to help reduce this variability.

Concrete is very sensitive to temperature and moisture at early ages and any deviation from standard procedures is a basis for rejecting results of these acceptance tests as it increases the likeli hood of failing test results of acceptable concrete. This has implications to the project cost and schedule.
