Study on properties of recycled tire rubber modified asphalt mixtures using dry process.

Abstract

To minimize waste tires pollution and improve properties of asphalt mixtures, properties of recycled tire rubber modified asphalt mixtures using dry process are studied in laboratory. Tests of three types asphalt mixtures containing different rubber content (1%, 2% and 3% by weight of total mix) and a control mixture without rubber were conducted. Based on results of rutting tests (60[degrees]C), indirect tensile tests (-10[degrees]C) and variance analysis, the addition of recycled tire rubber in asphalt mixtures using dry process could improve engineering pro
