摘要

The purpose of this research was to determine the rutting effect of asphalt mixture by adding worsted tires as a substitution of granular material. The study started with a description of granular material, asphalt and plastic wasted properties, followed by the result of the optimum asphalt binder content obtained in the Marshall test. It concludes with the Marshall tests performance and rutting adding wasted tires as a substitute of granular material. Wasted rubber was introduced in three different geometrical shapes: powder pieces of rubber of 1.5 centimetres long and a combination of powder and pieces. The results obtained showed that there is a reduction on permanent deformation of 13% by using powder of rubber and 23% by using pieces of rubber.
