Study and Application of Heat Recycle Technology for Asphalt Concrete

The plant-mixing hot recycling is a new asphalt technology, which was created in recent years. According to the studies, it has significant economic profits and social profits and can be used in road maintenance variously. The recycling material was designed by Marshall Experiments in this paper. Though the performance tests, the plant-mixing hot recycling was of good high temperature stability, low-temperature crack resistance, water stability and anti-fatigue performance etc. The test sections were built in the right amplitude k107 similar to k108 of Jing-Zhu expressway of Hubei in August 2005 and the plant-mixing hot recycling was used in double-track of the State Road 107 of Xiaogan in July 2006 to check the performance. No signs of water damage and wheel rut for a long time had been discoursed. Comparing with the new asphalt mixture, the saving proportion of the plant-mixing hot recycling materials is considerable.
