Sub Base Layer

WET MIX MACADAMIt is a road base material consisting of crushed rock/slag usually premixed with controlled amount of water sufficient for adequate compaction.

BITUMINOUS MACADAM

> Bituminous macadam consists of aggregate and appropriate binder, mixed in a hot mix plant and laid with a mechanized paver. > It is an open graded mixture suitable for base course and is laid in a single course or in multiple layers on a previously prepared base.

AGGREGATE COARSE AGGREGATE

The coarse aggregate consists of crushed rock,

crushed gravel or other gravel or other hardmaterial retained on 2.36mm sieve.
