At the same time, the first movable plate 13 pushes the piston 46 downward, and continuously squeezes the gas in the support groove 14 into the elastic airbag through the air pipe 47. After the compaction roller 12 descends to the compaction height, the compaction can be carried out. After the compaction operation is completed, the compaction roller 12 rises, the pressure on the first movable plate 13 decreases, and the elastic airbag contracts to squeeze the internal gas back to the support groove 14 through the air pipe 47. At the same time, The piston 46 rises under the push of the increasing amount of gas in the support groove 14, and then pushes the first movable plate 13 back to its original position; in order to prevent the first movable plate 13 from rising excessively and leaving the support groove 14, a limiting strip 45 can be provided on the inner wall of the support groove 14 near its top; the piston is an elastic rubber piston; during the compaction process, the support groove 14 and the first movable plate 13 can intercept the asphalt mixture under the compaction roller 12 to prevent the left and right ends of the asphalt mixture from collapsing due to excessive compaction pressure, thereby improving the paving quality.

At the same time, the second movable plate 32 moves along its corresponding third limit slide groove.
