Transportation Applications of Recycled Concrete Aggregate

Limit haul distance: Recycled concrete is crushed and the entire aggregate product can be used as a base material according to specifications, therefore generating no waste. This can be done on the project site or at nearby recycling plants, eliminating the transportation to distant disposal sites and the hauling in of virgin aggregate.
