Asphalt pavement is one of the main structural forms of high-grade highway in China. As a new technology of asphalt pavement, double paving technology is popularized in construction, which can shorten the construction time and improve the working efficiency. In this paper, the basic principles, key technical characteristics and application of asphalt pavement pavement are analyzed, respectively. The purpose of this paper is to provide technical guidance for application of double paving…

In this paper, a brief introduction construction principle micro-surfacing and slurry seal construction technology, construction and technical characteristics applicable to the construction area. Slurry seal and micro-surfacing, which greatly increases the speed of construction compared to other construction methods of its construction speed, energy use, the higher its energy-efficiency and greatly improve the overall effective construction.[url=http://wpcgreenfloor.com/index.html]Seven…

How to properly store firearms Roller: Rollers how proper storage is mechanical roller mechanical operator should have the knowledge. In particular, many mechanical roller may not be used again for a long time, or after a project is finished, you need these machinery and equipment stored for long periods. This time need mechanical roller how to correct long-term storage has become an important question, how long ...

Small mechanical roller proper…

Reasonable choice of road construction equipment and match. Road Construction subgrade, road and bridge engineering construction engineering etc basis having used sequentially corresponding construction machinery to complete. And the kind of road construction machinery, models, specifications many, each with its own technical performance and operating range. In order to ensure the quality of road construction, time and shelf life to complete the task, get the best economic and social…

Asphalt concrete pavement milling performed using milling machine. Before construction to determine the scope of the request of the milling, milling in the field release sample line. At one end section of the milling required sequential milling, milling try once completed, except for special reasons, can not be an intermediate pause. Mechanical milling of waste centralized transportation of waste to the designated place, followed by artificial loaders asphalt debris cleanup, and trimmed…

In modern road traffic, more than 90 per cent of road asphalt pavement, road transport bear about 80%, so the quality of asphalt pavement directly affect the effectiveness of transport. According to statistics, China's current road system around 18000 Road conservation classes, often on the road conservation and restoration. In road maintenance work, the need to dig for damaged parts cut its workload accounted for more than half of the entire repair workload. Before the 1980s, such work is…
