    To Determine Crushing Value Of Given Road Aggregate

    DETERMINATION OF AGGREGATE CRUSHING VALUE. 1) To determine the aggregate crushing value of coarse aggregates 2) To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.Aggregate Crushing Value Test Determine Aggregate. 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 construction is expressed by numerical index.Aggregate impact and crushing testLinkedIn SlideShare Aggregate impact and crushing test . is recorded to the nearestwhole number as the Aggregate Impact Value.The AIV is normally about 105 per cent of the Aggregate Crushing Value and itcan be used for the same purpose. . e.g.,Australia and New Zealand, only use the latter test.DISCUSSION(a) Report the geological description of the aggregate .Aug 11, 2020 It is recommended that the crushing value of aggregate should be less than 30 . If it is than 30 then 10 finer aggregate is suggested to use. The aggregate whose crushing value is less than 30 can be used for cement concrete road. The aggregate whose crushing value is less than 40 can be used for wearing surface. This test must be.
