Project Background：
Polyurethane is a kind of polymer material with excellent performance. The project uses polyurethane adhesive instead of asphalt to improve the road performance and durability. The research results are beneficial to realize the engineering application, standardized construction and industrial production of polyurethane adhesive materials in pavement engineering.
1. To develop and finalize a polyurethane adhesive for pavement according to the requirements of road performance and construction performance;
2. To propose the material composition design method and technical index system of polyurethane mixture;
3. To establish the construction technology and quality control method of polyurethane pavement based on road scene.
