Dec 29, 2014· 1. INTRODUCTION ON AGGREGATE IMPACT TESTING MACHINE Ashian Engineers Company India By Ashian Team 2. Principal: • Toughness is the property of a material to resist impact. Due to traffic loads, the road stones are subjected to the pounding action or impact and there is possibility of stones breaking into smaller pieces.
The stability and quality of roads are thus checked by carrying out several tests. One such test is the Aggregate Impact Value Test. The impact test is a type of quality control test for highway pavements and is used to check the suitability of aggregates to be used in the construction of highway pavements.
