aggregate crushing value coarse aggregate

aggregate crushing value coarse aggregate

Thecrushingofcoarse aggregatein PA mixture is caused by the excessive contact pressure betweenaggregates, so thecoarse aggregatesare more easilycrushedby vehicle load. So, thecrushing valueofcoarse aggregateis very important for the durability of PA mixture [ 1 – 3

    It is recommended that the crushing value of aggregate should beless than 30%.If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than30%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 done before it comes to road and pavement construction. …
