Table 5.4 presents the statistical data of the LA abrasion mass loss aggregate crushing value ACV and aggregate impact value AIV obtained from 307 RA samples. As expected the LA abrasion results suggest that the resistance to fragmentation of RA in descending order is RCA MRA and RMA. However this trend is not clear in the case of AIV and ACV.

Impact Tester or Clegg Hammer in evaluating existing aggregate-surfaced low-volume roads to manage traffic during spring breakup and in designing surfaces. In addition to correlating the Clegg Hammer with a Benkelman Beam and Falling Weight Deflectometer several preliminary tests were
AGGREGATE IMPACT VALUE TEST-10 IMPORTANT Aggregate impact value test gives an indication of aggregates toughness property i.e. property of a material to resist impact Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below.
Aggregate Impact Value Test Apparatus MTAT -14 It may be defined as the material to resist impact is known as toughness. Due to movement of vehicles on the road the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregates should therefore have sufficient toughness to resist their disintegration due to impact.
