Study on the application of modified bitumen technology in the maintenance engineering of secondary highway

The normal temperature of modified asphalt mixture has realized the asphalt pavement under the condition of the special environment, construction and maintenance, according to the provincial highway 202 line K0 + 000 ~ K3 + 100 section of the normal temperature of modified asphalt macadam mixture pavement test section construction, preliminary summarized in Long Dong region, the related technical index of the modified asphalt mixture under normal temperature, construction process control, etc., it provides some basic test data and construction experience for the promotion of this technology. The research is of great significance to the popularization and application of technology.
