Application of Foam Asphalt Cold Regeneration Technology in Hatong Expressway Maintenance Project
According to the current situation and diseases of the old pavement of Hatong Expressway,the mix ratio of asphalt mixture is redesigned to test the performance of asphalt mixture,and the local cold regeneration and repair scheme is adopted.The results show that according to the set grading of asphalt mixture,when the optimal moisture content is 5.4%and the optimal dosage of foam asphalt is 2.3%,the cracking strength of the recycled asphalt mixture meets the specification requirements.
