Asphalt concrete pavement construction usually needs paving much than the designed width. When installing curbs, excess asphalt will be removed, so it is laborious and the removal of asphalt pollutes the environment. For solving such problems, asphalt concrete pavement side mode technology can be adopted and asphalt concrete pavement side mode paving machine is designed. This paper introduces the overall structure, operating principle, key structure of the system and PLC control process. The applications of asphalt concrete pavement side mode paving machine can accelerate the speed of paving and improve the quality of side mode of pavement, production efficiency and reduce cost.
