PURPOSE: A plastic curve expansion joint for a concrete slab is provided to process plastic according to the color of concrete surface. CONSTITUTION: A plastic curve expansion joint for a concrete slab comprises curvilinear plastics(1,2), a lower cross section steel protection plate(3), a horizontal dowel bar(4) and a dowel insertion bar. The curvilinear plastics are respectively fixed in the upper side terminal of division section of a concrete slab by using a concrete coupling anchor(6). The lower cross section steel protection plate is arranged in the lower part of the curvilinear plastics one side. The horizontal dowel bar is horizontally projected in the outer side of the lower cross section steel protection plate. The horizontal dowel bar is installed in order to be moved to the division section of the slab in opposite side. The dowel insertion bar is exposed on the division section of the slab in opposite side.
