Aggregate Size in Hot Mix Asphalt (HMA) Hot Mix Asphalt (HMA) is the most common type of asphalt used in road construction. The aggregate size in HMA must be carefully selected to balance strength and workability. Coarse aggregates provide the necessary load-bearing capacity, while fine aggregates ensure a smooth and compact surface.
ABC helps control surface water runoff by providing a stable and well-draining foundation. This prevents water from accumulating on the road or pavement surface and minimizes the risk of erosion. 4. Can ABC be used for residential driveway construction? Yes, Aggregate Base Course is commonly used for the construction of residential driveways.
