The drive gear that transmits rotational force to the flattening roller and the shaft of the male gear are preferably disassembled and assembled by a connecting bar while being installed on the motor shaft of the moving wheel.

The guide roller at the front or the rear of the flattening roller can be attached and detached, and the guide roller at the front or the rear is replaced with a blot equipped with a vibrator, and a screed operation is applied while vibrating using a blot on the flattened pavement surface. As a result, aggregates with a high specific gravity sink to the bottom, and raw materials such as relatively light cement particles and sand are allowed to float, so that a large amount of sand and cement particles can be distributed on the surface.

As a result of the above operation, when a time of 120 to 180 minutes has elapsed, the surface moisture in the sand and cement gradually decreases after the bleeding and latency process has elapsed and the viscosity increases. The paste layer on the surface of the pavement, which has high viscosity, becomes clear when the design is engraved on the surface in the form of a stamp or brush, and the same effect can be seen even after a long period of time. If the surface treatment process by such a bllot is not carried out, it is difficult to realize a distinct shape if animals or plants are embossed or engraved due to the aggregates on the surface, rough brush, or honeycomb design. . In order to solve this problem, it is very important to apply vibration and finish the surface.
