SYNOPSIS OF RECYCLED ASPHALT PAVEMENT (RAP)

What is Asphalt Recycling? - Pavement Recyclers

Sep 17,  · Asphalt recycling starts with recycled asphalt, which contains reprocessed pavement. According to the Federal Highway Administration, reclaimed asphalt (otherwise known as RAP) starts with old, broken or damaged asphalt. “Reclaimed asphalt pavement (RAP) describes removed and/or reprocessed pavement materials containing asphalt and aggregates.

Asphalt Pavement | Construction & Demolition Recycling

According to the Asphalt Pavement Alliance, reclaimed asphalt pavement (RAP) can be recycled into the pavement that is as high, or even higher, in quality as pavements made of all- materials. And, the same material can be recycled again and again; it never loses its value. The asphalt cement—the glue that holds the pavement together
