EVALUATION METHOD OF CRACK RESISTANCE AT HIGH TEMPERATURE FOR RECYCLED ASPHALT MIXTURE
Pavement recycling has been conducted for more than 40 years, and recycled aggregate has been used multiple times depending on the region. Therefore, there is concern that the quality of recycled aggregate would deteriorate. Then, various studies have been conducted on the effect of the degree of deterioration of the regenerated aggregate on the recycled asphalt mixture. The authors have previously clarified that it is possible to evaluate the crack resistance at high temperature of the recycled asphalt mixture by the splitting strength ratio and the high temperature Cantabro loss rate using the recycled aggregate made in the laboratory. Therefore, in this study, the properties of the recycled asphalt mixture were examined using the recycled aggregate used at the actual pavement site. As a result, similar to the above results, it was possible that the splitting strength ratio and the high temperature Cantabro loss rate could be applied as an evaluation method of crack resistance at high temperature. Then, specification range of these evaluation indexes for recycled asphalt mixture was proposed.
