PURPOSE: A voltage unit for road pavement is provided to reduce the cost by making the density of asphalt concrete dense during making the surface even, and minimize the cooling time of asphalt concrete. CONSTITUTION: A voltage unit for road pavement comprises; a cooling part(2) installed in the lower side of a frame(1); a roller part(3) installed in the rear side of the frame(1); and a weight installation part(4) formed in the front side of the frame(1). In the front, rear side of the frame(1) filled with water, a front and rear part rollers(11,12) are installed, and the rollers consist of numerous rubber roller(111). A cooling part consists of a casing, a cooling water tank and a diffusing pan. A roller part(3) comprises; a bracket(32) having a finish roller(31); a connection rod(33) which is formed in the both sides of the bracket(32), and fixed by a lift part(34) installed in the frame(1); and a connection shaft(35) which is formed in the front side of the bracket(32), and a tilting cylinder(36) fixed in the frame(1) is connected. In the weight installation part(4), a weight(42) is installed.
