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.
