AN OVERVIEW OF RECLAIMED ASPHALT PAVEMENT

2016-8-29  In the report of Collins and Ciesielski (1994), RAP is a product of asphalt pavement removal and is the primary recycled material used in asphalt concrete. Milling machines break down the existing asphalt concrete pavement into discrete particles as shown in Figure 1 to produce RAP. It can be estimated more than 100 million tons of RAP are produced every year in the United States. Fractionated RAP (FRAP) is produced to afford extra control over RAP particle size, mastic content, fines, and overall quality. Specifically, the introduction of FRAP has allowed mix designers to meet Superpave mix design volumetric specifications more according to consistently. Hot Mix Asphalt (HMA) materials are 100% recyclable since studies have shown that materials present in old asphalt pavements which contain both asphalt and aggregates still retain considerable value which can be incorporated into virgin asphalt mixtures. The term Reclaimed Asphalt Pavement (RAP) for these reusable pavements has proven to be economical and environmentally sound with the use of RAP

Let’s rap about RAP. Reclaimed Asphalt Pavement

Once the surface of an asphalt road has surpassed its life span (about 25 years), it is milled off and becomes RAP. RAP is a “treasure trove” of pre-processed road-building materials and consists of two main compo-nents, aggregate and asphalt cement. Aggregate makes up about 95 percent of the pavement and the remaining 5 percent is asphalt ce-ment, which binds together the aggregate, adding strength and flexibil-ity to the pavement.
