1Rubber Paving Machine's impact on pavement flatness
(1) The effect of the performance of the paver on the smoothness of the road surface. Rubber Paving Machine is the leading machinery for rubber pavement construction, and its performance has a great impact on the quality of pavement construction.
(2) improper adjustment of paver technical parameters: 1 paver screed width is asymmetrical, not on a plane, when the combination of screed width and the machine itself is asymmetrical, the paver is easy to go during driving, and Under the inertia of the mixture, the pressure of the screed front and back mixture is inconsistent, resulting in the difference in paving thickness on the cross section; 2 when the paver has a large paving thickness, the aggregate particle size is relatively large and the compactness is required to be high. If the position of the spiral feeder and the leading edge of the screed is too small, the actual paving thickness cannot be satisfied, and the paving layer is corrugated, and the pavement flatness is lowered; 3 when the paver spreads the thin upper layer If the vibrator frequency is too high, the screed will resonate, which will affect the flatness.
(3) Spreading speed of the paver. During the process of paving the asphalt mixture, the paving speed is arbitrarily changed, so that the paving speed is uneven, resulting in the floating screed falling and falling, the paving layer compactness is not constant, and the local thickness of the paving layer is changed. Affect the pavement smoothness after paving. In addition, the paver stops frequently during the middle of the paving, and the downtime is long. The loose layer of hot mix will sink slightly under the self-weight of the screed, especially the mixture ratio is too large. When the temperature is high and the gradation is fine, this phenomenon is more prominent, which causes the pavement surface to have a step, which affects the flatness of the road surface.
