Joints on concrete road prevent failure and crack securing the moderate space when concrete slab expands and contracts as a function of varying temperature throughout all seasons. Filling joint sealants in joints can prevent the interruption of slab movement and failure due to the infiltration of alien substances, and also can prevent crack caused by freezing and thawing and Dowel bar corrosion resulted from water - rainfall and snowfall infiltration through the inside the pavement. They lead to the improvement of the commonality of road. This paper evaluates physical strength, weatherability and deicer resistance of a two-year aged sample from joint on concrete road and its virgin sample. It was found that there are significant differences in aspects of weatherability and adhesive force between the tested sample and silicon materials.
