In current chinese technical specification, the crushing value of the coarse aggregate for surface layer of asphalt pavement is no greater than 26% so, the crushing value standard of basalt coarse aggregate used in PA mixture should be increased to not more than 26%1.48 17.6%.two models available: comprising 150 mm nominal diameter steel cylinder, plunger, base plate, tamping rod and measure 115 mm diameter 180 mm deep.used for aggregate passing 12.7 mm and retained by 9.52 mm sieve. weight: Kg approx. comprising mm nominal diameter steel cylinder, plunger, base plate, tamping rod and measure mm diameter mm deep.
Get Pricethe aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. the oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing the specified IS sieve to the total weight of between aggregate crushing value and ten percent fines aggregate crushing value for some aggregates in nigeria. such a mathematical relationship, usually established through regression modelling on data collected, is useful in saving time and money cost on site through estimating one variable when another is known.
