Abstract
The present invention discloses a method of hot recycling repairing by optimizing a proportion of an asphalt mixture on a pavement alignment variation section. According to the method of the present invention, by regulating and optimizing the proportion of a recycled asphalt mixture, internal frictional resistance and cohesion of the recycled asphalt mixture are improved, elastic modulus and shear strength of the recycled asphalt mixture are increased, overall bearing capacity of an asphalt pavement is improved, and diseases such as tracks caused by vehicle loads are effectively resisted. The pavement asphalt mixture is made to adapt to and be enough to bear additional loads increased manifold without generating early defects and road diseases. Therefore, the overall service life of a road is further prolonged.
