PURPOSE: A paving and patching concrete composition and a road paving and patching process using the same are provided to improve the adhesive force and the elasticity force by containing polyvinyl acetate. CONSTITUTION: A paving and patching concrete composition contains polyvinyl acetate. The polyvinyl acetate is the polymer which is obtained by polymerizing vinyl acetate. The content of the polyvinyl acetate is between 2 and 33 weight%. A paving and patching concrete composition contains 0.1 to 10 weight% of silica and 0.05 to 2 weight% of an additive. The additive is selected from a dispersing agent, a stabilizing agent, an antifoaming agent, a surfactant, an anti-aging agent, an anti-flowing agent, and a thickening agent. A road paving and patching process includes the following: Mortar is formed by mixing cement and sand. Polyvinyl acetate and water are mixed. The mortar and the mixture are mixed and applied.
