Asphalt Paving - Binder & Topcoat » Alpha Paving
The binder, which is sometimes called the base coat, is a load-bearing course consisting of aggregate and hot-mix asphalt. Because the binder must be strong, it typically contains aggregates that are approximately 0.75 inch in size. In addition to having the strength to bear the load, binder must have the ability to withstand seasonal ...
