Rubber-modified asphalt pavements have been used in Sweden and the United States since the 1970's. In these applications ground recycled tire particles (0.25 inch minus) are added to a gap-graded aggregate and then mixed with hot asphalt cement. The benefits of adding rubber to the mix include increased skid resistance...
The research undertaken consisted of the study of three topics
affecting the performance of asphalt concrete mixtures, that is, mixing
moisture, oxidative aging and higher tire pressures and axle loads.
This thesis presents the findings of the research comprising these
three topics.
In the first study, the effects of mixing...
