Top Size or Maximum Particle Size--The sieve on which 100 percent of the material will pass. Nominal Maximum Particle Size--Smallest sieve opening through which the entire amount of the aggregate is permitted to pass.

Inquiry price nowCoarse Aggregate The aggregates which pass through the 80 mm sieve and are retained on the 4.75 mm sieve are called as coarse aggregates. Fine Aggregate All the aggregates which pass through the 4.75 mm sieve are called as fine aggregates. On the basis of particle size distribution, the fine aggregates are classified into four zones (Zone I to Zone IV.)

Inquiry price nowOne of the model in which pavement material can fail is by crushing under compressive stress. A test is Standardized by IS2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
