Abstract The road polymer stabilized crushed stone base layer is different from the inorganic binder base stabilized materials, and its strength and integrity are mainly achieved by the polymer bonded crushed stone material after evaporation of water during the curing period. This work deals with vibrating polymer crushed stone base-stabilized samples. The change between water content and structural strength of the material under different conditions of curing are analysed. Based on this, the curing period standard that meets the road performance requirements is proposed, which can be used as the engineering application basis for the road polymer stabilized crushed stone base.
