Introduction abrasion test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. this test is suggested by aashto t 96 or astm c 131 resistance to degradation of small
Has been harmonised throughout the european union. some familiar aggregate tests previously used in the uk and ireland, such as aggregate crushing value, ten percent fines value, aggregate impact value, and wet attrition value, have been withdrawn from use, and do not now have the status of a national standard.
In order to evaluate the resistance to impact of aggregate, the aggregate impact test is conducted. aggregate impact value gives the idea about how much impact load can be resisted by aggregate. actually, aggregate should be sufficiently tough to resist their disintegration due to impact. this distinctive property is measured by impact value test.
2.36mm sieve size to the total weight of the sample. the aggregate impact value should not exceed 30 for use in wearing course of pavements. maximum permissible values are 35 for bituminous macadam and 40 for water bound macadam. the plastic coated aggregates were subjected to this test and the results are tabulated in table

The los angeles test is a measure of degradation of mineral aggregates of standard gradings resulting from a combination of actions including abrasion or attrition, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. the los angeles l.a. abrasion test is a common test method used to indicate aggregate toughness and abrasion
The value of aggregate impact test should not be more than 45 by weight of aggregates, used for concrete other than wearing surface. an impact value 35 is permissible for the bituminous macadam. maximum permissible impact value for the water bound macadam is 40.
