Test Method: IS: 2386 (P1) 1963. Impact Value: This test helps in determining the value which indies the ability of an aggregate to resist crushing. The lower the figure the stronger the aggregate, the greater its ability to resist crushing. Test Method: IS: 2386 (P .
· Crushing test. One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 partIV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
Mar 28, 2021 · Aggregate Crushing test (IS 2386 (Part 4):1963 BS 812–110:1990) Aggregate crushing test values indies the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads. Higher crushing strength means lower ...
