Abstract: A complex-mixed in-situ asphalt thermal regeneration method were developed to help better maintenance of the highway pavement with distress of rutting cracks potholes. The procedure of proposed method were introduced in terms of raw material testing, grading design and mixture performance verification. The performance of proposed method were analysed based on the physical engineering system, the construction technology and quality control measures. The results show that: re-mixing The type of hot-in-place recycled asphalt pavement has good high and low temperature performance, water stability and anti-skid performance. It is recommended to be promoted and applied as a new type of green ring maintenance method. The research content of this article can provide reference and reference for similar engineering applications.
