Evaluation of performance of recycled reclaimed asphalt pavement (RAP)
Asphalt ages gradually in the process of road construction and service due to the action of heat, oxygen, ultraviolet, moisture and other natural environmental factors. As a sustainable technology, the recycling of the aged reclaimed asphalt pavement (RAP) can bring significant environmental and economic benefits. During the recycling of RAP, the regeneration of aged asphalt is the key to guaranteeing the performance of recycled RAP. Based on a heavily damaged asphalt pavement in Dalian, China, this study evaluated the performance of the aged asphalt extracted and recovered from the RAP of this pavement, and several performance tests were performed on the obtained aged asphalt. By analyzing of its aging mechanism, three regenerating methods were adopted, and the performance of the three recycled asphalts was tested and compared. In such a manner, the regeneration effects of the three methods were objectively evaluated and the optimal regeneration approach was rationally determined.
