Cracks, pavement cracks are caused by many factors, many of which are structural reasons. For example, fatigue cracks are caused by loss of road stiffness and repeated rolling of traffic vehicles. Vertical fractures, cracks and cracks are caused by material and design factors, both for pavement and for material aging and environmental the reason. The reflection cracks are caused by the presence of cracks in the existing cracks or the connection in the cement concrete pavement.
With the passage of time, the road surface gradually aging, the aging of the asphalt depends to varying degrees on the environment and the chemical properties of asphalt, which will lead to pavement fracture, surface structure loss and the usual cracks and pits. Pits are caused by the loss of fines in the mix or the smaller pavement pellets and pavement subsidence.Road Sealing Machine - Road Machinery Equipment Manufacturers - Doan Machinery
Conclusion Based on the oil-like analysis technology on-demand maintenance method, without the need to disassemble the machine, you can understand the mechanical running status, and can be found in advance of the hidden trouble, in the non-construction time warranty to eliminate the hidden trouble, not only improve the mechanical performance , To extend the mechanical life, greatly reducing maintenance costs, but also greatly reduce the mechanical failure caused by forced shutdown, affecting the progress of the construction process. In today's increasingly competitive environment, the construction units can only rely on scientific and technological progress to survive and develop. Therefore, the oil sample analysis technology in highway engineering machinery, especially large, important machinery and equipment maintenance in the application is imperative.
