Advantages of Asphalt EAPA

In many cases milled asphalt can be reused without additional crushing. It is common to resurface worn out asphalt by milling the top layer, so the new asphalt can be laid on an even surface. Many asphalt plants have the appropriate equipment to reuse reclaimed asphalt (RAP). The asphalt industry is one of the forerunners of recycling and reuse.
