Abrasion Resistance and Rutting Resistance of Micro-Surfacing with Crumb Rubber of Dry Process

Abstract

In order to improve the common micro-surfacing is easy to loose and fall off, and improve the wear-resistance and anti-rutting performance of pavement, this paper uses waste rubber powder as the filler of micro-surfacing mixture, and adopts the method of dry adding. The test of micro-surfacing with crumb rubber of dry process based on APA test was carried out at 40 °C without water. Asphalt pavement analyzer shows that the micro-surfacing with crumb rubber of dry process has better wear-resisting and anti- rutting performance.
