According to the relevant information, China's construction of cement concrete road has reached more than one million kilometers. Cement concrete pavement because of its high structural strength, large carrying capacity, good stability, the use of durable, low maintenance costs, the cost of moderate and many other advantages, but also because of its existence of poor anti-skid properties affect traffic safety, vehicle Driving noise and driving comfort, so that the use of constraints. All the experts at home and abroad have been trying to find a solution to the cement concrete pavement defects in the process and methods. In particular, how to solve the problem of anti-skid and noise reduction of cement concrete pavement has done a lot of theoretical research, laboratory test and practical engineering experiment. It has found many methods, such as: wool, chisel, abrasion, Milling, grooving, dew, cover, corrosion and other mechanical and chemical processes.Road Sealing Machine - Road Machinery Equipment Manufacturers - Doan Machinery
Which groove method by more positive. Especially for a few years has been used, the wear of cement concrete pavement to restore anti-skid performance, groove process is considered a comprehensive effect of a better way; unequal spacing groove, but also that not only has a good anti-skid effect, But also has a better noise reduction effect. The milling machine is equipped with four milling heads on a machine. At the time of milling, each milling head rotates around a central axis while rotating at its own, thereby effecting the rotation of the surface being treated and turning the milling.hand compaction rollers jackhammer chicago the hole metallurgical chemical equipment for mining property
