201442ensp;0183;ensp;Strength is a measure of the ability of an aggregate particle to stand up to pulling or crushing forces. Elasticity measures the quot;stretchquot; in a particle. High strength and elasticity are desirable in aggregate base and surface courses. These qualities minimize the rate of disi ntegration and maximize the stability of the compacted material.
