Sep 12 2015 One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS 2386 part-IV 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.

Jun 22 2021 Types of Test Carried Out On The Coarse Aggregates 1. Crushing Value Test of Aggregate IS 2386 Part IV -1963 The crushing value is the relative measure of the resistance which can be offered by the aggregate to the crushing under the action of the gradually applied load. 2. Impact Value Test of Aggregate IS 2386 Part IV -1963
May 17 2019 The 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
Jul 18 2021 Ans. The most commonly used coarse aggregate size in road construction is 40 mm 50mm 60 mm or design requirements. For various layers of the road different sizes of aggregates are used. Q. What is the abrasion value of aggregate Ans. The abrasion value of an aggregate is the value that determines aggregate resistance to wear.
