Research on the Application of Modified Asphalt in Highway Construction and the Improvement of Pavement Durability

This study focuses on the application of modified asphalt in highway construction and the improvement of pavement durability. Analyzing its material properties, construction techniques, and actual effects, it is shown that modified asphalt can significantly enhance the fatigue resistance, rutting resistance, and crack resistance of road surfaces, and perform well in complex climates and heavy traffic. Practical cases demonstrate its successful application in different road sections, providing technical support and practical basis for highway construction. Finally, looking forward to the development trend of highway pavement material technology, the prospects of intelligent materials and environmental protection technology are mentioned.
