Get PriceAbrasion resistance. Under the conditions of the test, the results can be reported or can be compared items subjected to similar tests. Such standardized measurements can produce two quantities: abrasion rate and normalized abrasion rate (also called abrasion resistance index ). The former is the amount of mass lost per 1000 cycles of abrasion.
Get PriceThe ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road .
