Abstract

To study the application of construction waste in road subgrade, this paper conducted a large number of indoor tests to investigate the mechanical properties of cement-modified construction waste, and analyze the changes in mechanical and shrinkage properties of cement-stabilized construction waste after adding polypropylene fibers. The results show that adding a certain amount of polypropylene fiber to cement-stabilized construction waste significantly improves the unconfined compression strength and splitting strength, and notably enhances the anti-shrinkage ability, meeting the road performance requirements. Additionally, there is an optimal value for the added content of polypropylene fiber.
