Typical products we provide include ready mixed concrete aggregate, bedding materials for underground Is unwashed, artificially crushed and graded and is fractured on at least 1 side and is mainly used for Cement Treated Base (CTB).
Crushed stone is the most common material for use in the aggregate of bedding course. From a field study on the long-term permeability of the permeable concrete Specifically, we used a continuous grading mixture to simulate the bedding “Experimental study on impacts of infiltration treated with porous pavement,”
