Rubberized asphalt - Wikipedia

Rubberized asphalt concrete (RAC), also known as asphalt rubber or just rubberized asphalt, is noise reducing pavement material that consists of regular asphalt concrete mixed with crumb rubber made from recycled tires.Asphalt rubber is the largest single market for ground rubber in the United States, consuming an estimated 220,000,000 pounds (100,000,000 kg), or approximately 12 million tires ...

Energy consumption and environmental impact of rubberized ...

4/10/2018 · The warm mix asphalt (WMA) technology could reduce 30 °C of the mixing temperature of rubberized asphalt, and thus there was approximately 20–25% of fuel savings (Xiao et al., 2009a). The mixing and compaction temperatures of rubberized asphalt were reduced by adding warm mix additive (Behl et al., 2013).

Advances in Materials Science and Engineering - Hindawi

This study aims at comparing the permanent deformation of Stone Mastic Asphalt (SMA) rubberized asphalt mixtures produced by the wet process. In this study, rubberized binders were prepared using two different blending methods, namely, continuous blend and terminal blend. To study the creep behaviour of control and rubberized asphalt mixtures, the dynamic creep test was performed using ...

THE PROCESS OF PRODUCING RUBBERIZED ASPHALT

The dry process includes mixing the rubber particles with aggregates prior to addition to asphalt. This process provides a way to blend the crumb rubber with the asphalt and aggregate without the use of the special equipment needed in the wet process. There are some technical problems associated with this method, but new technologies are being ...

3/10/2018 · However, with the development of new mixing technique, such as TB, rubberized asphalt binder behaving like polymer modified binder can be applied in various mix gradations. Recently, more and more agencies choose open graded asphalt mixture with rubberized asphalt to obtain a “super quite” and good skid resistance pavement (Partl et al., 2010).
