Asphalt Pavement Recycling with Reclaimed Asphalt Pavement

Reclaimed Asphalt Pavement (RAP) in Asphalt Mixtures ,Recycling asphalt pavement creates a cycle of reusing materials that optimizes the use of natural resources Reclaimed asphalt pavement (RAP) is a useful alternative to virgin materials because it reduces the need to use virgin aggregate, which is a scarce commodity inRecycled Asphalt Pavement,Therefore, many made modifications to the 1987 VDOT asphalt specifications (which permitted the higher RAP contents) to incorporate the new PG Binder system and Superpave gyratory mix design system Research shows that asphalt pavements made with recycled materials can perform the same as or better than those made with virgin materials
