As the saying goes, if you want to do a good job, you must first sharpen your tools. If you want to do the paving work smoothly, then the preparation work of the rubber paving machine must be done well before paving. Now, let me learn about paving with me. What are the preparations for the running track paver machine?
According to the technical requirements for the construction of the stable layer (sub-base, base), the working devices for installing and adjusting the runway road paver machine include the following aspects:
Assemble the screed of the rubber paving machine according to the width requirements of each layer of the pavement stabilization layer, and ensure that the screed is installed straight. If the paving width of one paver is not enough, two or three parallel machines can be used to eliminate the longitudinal seam of the stable layer.
Adjust the camber of the screed according to the requirements of the transverse slope of each layer of the pavement stabilization layer. When adjusting, consider the deformation of the screed during the paving process and the thickness of the pellets at both ends. According to experience, the two ends can be adjusted slightly higher. When paving the test section, measure the transverse slope of the paved road surface. If there is any deviation, re-adjust the camber of the screed of the rubber paver.
According to the requirements of the paving thickness, the position of the high-speed screw conveyor and the front baffle, and the ground clearance of the screw conveyor will directly affect the working load and paving speed of the running track paver machine. If the distance from the ground is high, the resistance of the running track paver machine is large; if the distance from the ground is too low, the paving cannot be carried out continuously. The adjustment of the distance of the screw conveyor from the ground depends on the thickness of the paving layer. In general, the distance from the screw conveyor to the ground is the thickness of the paving plus 5 cm.
