Conclusion. Following the Los Angelos Abrasion Test as mentioned above, we derived the abrasion value of the sample as 58.. From the table given above, the suitability of aggregates used for the pavements can be known.. For the sample calculation that was done here having an abrasion value of 58, the aggregates can be employed only for the WBM sub-base course.Its …

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

Aggregates Impact Test (AIV) Introduction: Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some …

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 …

AGGREGATE IMPACT TEST In conclusion,the percentage of aggregate's wear depends on the quality of aggregate. In this test, we can conclude that: The loss of aggregate = 1663 g The percentage of wear = 33.26% Lower abrasion loss values indicate the aggregate was tougher and more resistant to abrasion.

The aggregates should therefore have sufficient toughness to resist 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.
