Design and realization of paving machine for modified asphalt coil

The modified asphalt coil is widely used as the waterproof material in elevated railroad, high way etc. However, most of the asphalt is paving by manual work. An automatic and wireless controlling machine for the paving modified asphalt coiled is designed and studied according to the need of improving the efficiency and paving quality. This paper introduced the system design of the mechanism and the intelligent control of the paving machine. The paving machine is mainly controlled with MCU, PLC (programmable logic controller) and CAN (control area network) bus to realize, via obtaining signals from multi-sensors. Meanwhile, hardware and software of CAN bus and have been designed and studied. Two working mode can be selected, one is the automatic paving mode, the other is the steer state. The scene´s experiments shows that automatic paving machine can satisfy the need of paving process. And the automatic paving machine greatly improves the efficiency of the waterproofing paving in elevated railroad and high way.
