The Research Of Asphalt Concrete Pavement Side Mode Paving Machine

With the development of road construction technology, the asphalt concrete pavementhas become one of the most widely used road in our country, especially in the high gradehighway occupies the most proportion. So to promote the asphalt concrete pavementconstruction technology and the efficiency of construction are becoming more and moreimportant.Asphalt concrete pavement construction usually needs paving much than the designedwidth. When installing curbs, excess asphalt will be removed, so it is laborious and theremoval of asphalt pollutes the environment. In response to these problems, asphaltconcrete pavment side mode technology can be adopted, it can pave the side mode in theedge of the road two side before asphalt concrete surface paved. These will make asphaltconcrete pavement directly formed neat and straight edge in the process of paving.However due to the low speed, low efficiency, poor straight degree of manual installationside mode affect the promotional use. For solving such problems, asphalt concretepavement side mode paving machine is designed. It can automatically follow thepreviously laid tag line to walk and install side mode at the same time. The mechanicalstructure of asphalt concrete pavement side mode paving machine is designed, includingthe walking steering system, the side mode installation sysyem and the side mode nailingsystem. Paving machine automatic walk along the marked lines under the control of thewalking steering system, and complete the laying operation of side mode in the role ofinstallation sysyem and nailing system. It design steering control system based on singlechip, and redact the control programs; In order to better accomplish the intended action,suitable pneumatic actuators and control components are chosen. Programmable logiccontroller are chosen. According to the control flow, the ladder of programmable logiccontroller has been drawn by using WPLSoft software.The paving machine can complete the operation of asphalt concrete pavement sidemode automatically. It can accelerate the speed of paving and improve the quality of sidemode of pavement, production efficiency.
