Cold Recycling of Waste Asphalt Pavement in Cold Region

The characteristics of the mixture of recycled asphalt pavements with emulsified asphalt and cement, as the pavement material, was investigated in this research. Kantabro Loss test was used to evaluate initial performance of the recycling mixture and to propose appropriate parameter. Rutting test, split test and low-temperature bending test were carried out to evaluate the long-term performance. The performance of the mixture at low temperature was one of the most important factors to be considered to ensure its application in cold areas. The results showed that the performance of the mixture was effect by old mixes milled. The proposed application conditions of the recycled mixture were also discussed in this paper.
