Pavement performance and application of anion rubber-modified asphalt

Abstract

We have used a unique process to develop the first successful anion rubber modified asphalt mixture. Rubber and asphalt are used in equal proportions in the mix. Compared with conventional asphalt, the anion rubber modified asphalt show better pavement performance, and fully met the relevant specifications. The dynamic stability and failure strain indicators are better than those of SBS modified asphalt. Compared with traditional rubber modified asphalt, the amount of waste tires incorporated into this new rubber modified asphalt is much greater; the new asphalt also improved the air quality near the road, thus providing great economic and social benefits. © 2012 The Author(s).
