Points for attention in paving operation of RP952 asphalt paver
A paving direction indicator, paver driver to the front as a mark, notice the correction direction, should avoid a sharp turn. In the wide road in two or more times when paving, overlapping part of the longitudinal seam should be 30~50mm. If the overlap is too wide or too narrow will form a local convex or concave, affect the pavement quality.
Two, the best working speed in the range of 2~6m/min. When the paving speed is less able to obtain a larger degree of density, velocity mainly in order to improve productivity.
Three, when the stability of paving materials, paving thickness below the reference curve.
HB=175/117 Q=60H B by the formula V (P V=3/min, P =2.6t/m3), thus allowing the corresponding paving width of paver thickness.
Four, the feed must be uniform
1) feeding is uniform and continuous, which is an important factor affecting the quality of paving. The material accumulation height generally less than spiral diameter, helix radius should be not less than. Therefore, should adjust the feeding control valve to ensure uniform and continuous feeding.
2) truck to the paver when unloading, carefully aligned hopper, must prevent the collision, or the material sprinkled on the outside. If the crawler paver before the accumulation of material should be removed immediately, otherwise it will affect the smoothness of pavement paving.
3) with large tonnage dump truck, do not suddenly put inside the material are removed into the hopper should be gradually discharged. Otherwise the excessive track load, affecting the normal paving.
Five, pay attention to check the paving layer thickness
Operation angle between the screed and the ground (elevation) alpha size varies as the paving thickness, different materials, gradation. So stand should pay attention to check the paving thickness of the paving process, to adjust the size of alpha.
