Paving machine rolling

[quangongzi]

The rational combination of rolling technology and rolling machine has a great influence on the flatness. Initial pressure should be carried out at a higher temperature to not have to move, the principle of hair split. Initial pressure temperature should be based on asphalt consistency, roller type, paving the initial density and other factors determined by the trial shop. Roller should be slow and uniform speed of rolling, the initial pressure when the driving wheel in front to prevent the hot mixture is extruded uplift, rolling from the outside to the inside, from low to high rolling, rolling process shall not play Direction, brake, rolling must overlap, both to prevent overpressure, but also to prevent leakage pressure. Roller should be prohibited to stop in the non-cooling sections, preferably to stop on the structure. Joints must be carefully addressed, the construction unit is often not in order to save material and cut in place, causing poor flatness. The transverse seam is preferably a straight seam. The transverse joints must be handled by a team of handlers to ensure the smoothness of the seams.Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery

In short, the quality of the mixture, good construction machinery, good grass flatness, reasonable construction technology, adequate technical preparation, strict and scientific management, is to ensure and improve the asphalt pavement smoothness of the necessary conditions. Modern construction of the highway, the construction unit attaches great importance to the survival of the essentials of enterprises in the increasingly fierce competition in the market must be excellent construction machinery and equipment, reasonable organization and improve the management system and advanced management concepts can guarantee In the market to high-quality products to capture the market, with sound technical equipment to win the future. Through my construction summary, I bid construction of asphalt concrete pavement of the overall quality, in the degree of compaction, flatness, thickness and other comprehensive test indicators have been affirmed.
