What Is Rigid Pavement?

Semi-rigid pavement refers to the base layer constructed with soil or crushed (gravel) stone treated with inorganic binders such as cement and lime, and industrial waste slag containing hydraulic binders. It has the mechanical properties of flexible pavement in the early stage, and both the strength and stiffness in the later stage There is a large increase, but the final strength and stiffness are still much smaller than cement concrete. Because the rigidity of this material is between the flexible pavement and the rigid pavement, the base layer and the asphalt surface layer laid on it are collectively referred to as semi-rigid pavement.

This base layer is called a semi-rigid base layer.
