Aggregate with a LA value of less than 30 (LA 30) is considered strong enough for use in coating and road surface treatments (, surface dressing). Railway Ballast: The test is modified to test railway ballast, in that 5kg of 32/40, together with 5kg of 40/50, is placed in the cylinder with 12 steel balls and rotated for 1000 revolutions.

Strength is a measure of the ability of an aggregate particle to stand up to pulling or crushing forces. Elasticity measures the "stretch" 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.
Aggregate Crushing value is a measure of the strength of the aggregate. The strength of concrete largely depends upon the strength of aggregate. The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.
A. Aggregate size Maximum size of aggregate (MSA): MSA < 1/5 of the narrowest dimension of the form in which concrete is to be placed. Also: MSA < 3/4 of the maximum clear distance between the rebars Aggregate size affects the following concrete properties: .
