Recycling technology of aged asphalt pavement

Firstly, the current development of the technologies for recycling of reclaimed asphalt pavement (RAP) in China and abroad is introduced in this study. The theoretic evidence is supplied for the feasibility and means of the recycling technology for RAP by analyzing the aged asphalt recycling mechanism. On the basis of it, a series of recycling processes for RAP are stated in detail, including the performance assessment of RAP, mix design and construction techniques of recycling asphalt mixture. The traits and actual example of different construction techniques for RAP supplied a good consultation for its reasonable choice. All of them would play a role in the research, application and spread of the recycling technologies for RAP in China.
