Mix Design of Sup-13 Mixed with TOR and Crumb Rubber Using Dry Process

Abstract:

Pure crumb rubber asphalt mixture using dry process has certain requirement of mineral gradation with the potential disadvantage of uneven mixing under the traditional temperature. In this paper the gradation design of asphalt mixture Sup-13 mixed with TOR and crumb rubber using dry process was studied with the Superpave design method, pavement performance of asphalt mixture including high temperature stability, cracking resistance at low temperature and water stability was tested in the experiment. Results show that Superpave design method is suitable for the research on the asphalt mixture of TOR and rubber, with getting moving stability 3682 times/mm, failure strain 2573.8με, residual stability 84.8% and the ratio of freeze-thaw splitting 80.1%. The performance is so good to meet the requirements for asphalt pavement performance.
