The advantage of road pressing machine is that it can make the road base reach enough compactness by rolling when checking the road. The quota items of subgrade shaping and rolling, sidewalk shaping and rolling include artificially digging high and filling low, with an average thickness of 10cm, leveling the bottom surface, making it form the vertical and horizontal slopes required by the design, and compacting it. Road bed rolling inspection and sidewalk shaping rolling engineering, whether new or old road reconstruction projects, need to be calculated.
