Abstract
In order to help the use of hot recycled asphalt mixture under different amount of used asphalt in cold areas of China. The optimum asphalt content of hot recycled asphalt mixture with different old materials was obtained by using Marshall Test method. By analyzing the material composition of hot recycled asphalt mixture in cold and cold areas, the optimum amount of asphalt with 70% old material in hot recycled asphalt mixture in cold area is 5.065%, the optimum amount of asphalt with 80% old material is 5.14%, and the optimum amount of asphalt with 80% old material is 5.2%. This study provides practical engineering for hot recycled asphalt mixture in cold area reference basis.
