Importance of Impact Test on Aggregates. The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.

aggregate impact value. Values obtained in these tests are given in Fig.7. The tested aggregate impact value varies from 6.81% to 12.11%. Aggregate Impact Values (AIV's) below 10 are regarded as strong, and AIV's above 35 would normally be regarded as too weak for use in road surfaces. AIV values for both material tested are exhibit strong enough.
