Aggregate Crushing Value Calculator Test On Course And

Aggregate Crushing Value Test Step By Step Procedure It is recommended that the crushing value of aggregate should be less than 30 if it is more 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 Aggregate Crushing Value Calculator Test On Course And Aggregate used in road construction should be strong enough to resist crushing under traffic wheel loads if the aggregates are weak the stability of the pavement structure is likely to be adversely affected the strength of coarse aggregates is assessed by aggregate crushing test 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 crushing value is a What Is The Crushing Value Of Aggregates May 27 2020 the aggregate crushing value should not be more than 45 by weight for aggregates used for concrete other than wearing surfaces and 30 by weight for concrete to be used as wearing surfaces such as runways roads and airfield pavements see also basic units and measurements for civil engineers different types of cement
