The following description is a brief summary of the abrasion test. It is not a complete procedure and should not used to perform the test. The complete testing procedure can be found in: AASHTO T 96 or ASTM C 131: Resistance to Degradation of SmallSize Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine; Summary
The aggregate impact value is a calculation of the resistance to abrupt impact, bang or shock, which may vary from its resistance to steadily, applied compressive weight. Procedure: The test specimen includes the aggregates of size ranging from mm mm. Aggregates can be dehydrated by warming them at temperatue of 100110° C for a ...
• The crushing strength of aggregate cannot be tested with any direct test. There are some indirect tests to inform us about the crushing strength of aggregate. –Test method: Crushing value test Other Mechanical Properties of Aggregates: a) Impact value: Impact value of aggregates measures the toughness of particles by impact. Total 54 14
The aggregate impact value is expressed as the percentage of the fines formed the total weight of the sample Aggregate Impact Value (AIV) = (100*M2)/M1 Where: M1 =Mass of the test specimen M2 = Mass of the test specimen passing mm test sieve
