SYNOPSIS OF RECYCLED ASPHALT PAVEMENT (RAP) MATERIAL

The use of Recycled Asphalt Pavement (RAP) is allowed and encouraged in the construction of new roadways and pavements. Its use reduces cost and environmental impacts of road construction by reusing existing asphalt pavement. In Minnesota, existing asphalt pavement material is often crushed and blended with other aggregates to create aggregate

Reclaimed Asphalt Pavement (RAP) is the result of removing old asphalt pavement material. RAP consists of high quality well-graded aggregate coated with asphalt cement. The removal of asphalt concrete is done for reconstruction purposes, resurfacing, or to obtain access to buried utilities. The disposal of RAP represents a large loss of valuable source of high quality aggregate.
