The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and

RE: Proctor testing of 3/4" clean stone. Ron (Structural) 5 Jan 05 20:46. The problem with such gap-graded material is that there is very little unit weight difference between the max and min densities. The void ratio is so high that you have no opportunity to change it proportionally by a very large amount.
