Why Load On Aggregate In Crushing Strength Test Is Kept 40 Tonne

Actual crushing value of aggregate important points to remember 1it 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 2the aggregate whose crushing value is less than 30 can be used for cement concrete road 3the aggregate whose crushing value is less than 40 can be used for wearing.
