Alternative aggregates, consisting of recycled concrete and secondary aggregates from other industrial waste such as mining waste, slag and ash.

The crushed aggregate is allowed to pass through 2.36 mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn't exceed 30 percent.

Granulation is a process of consolidating solid particles in the size range of 1–500 μm into aggregates with larger sizes ranging from 2 mm to 10 mm ( Ennis and Litster, 1997 ). Presently, the commonly applied granulation methods in producing AAs can be divided into agitation granulation and compaction granulation.
