Bituminous Pavement Solving High Temperature Rutting Problem Firstly, Glass Fiber Geotechnical Grid

更新时间:2019-04-03 点击数:147

Our company produces a wide range of geotechnical materials, specifications, wide application, mainly used in highway, railway, airport, tunnel, water conservancy, electric power, and other projects in the field of water and soil conservation, environmental greening and other infrastructure construction, products by the engineering experts and users of the unanimous praise, and by the recognition and praise of relevant experts at home and abroad, are unanimously considered to be in the construction of the project. Ideal material. Especially in the construction of asphalt pavement, the requirement of geotechnical materials is even higher. The most suitable geotechnical material is glass fiber geogrid, which can effectively resist high temperature rutting, so it is widely used.

In some road construction, asphalt concrete has rheological behavior at high temperature, which is manifested in the fact that the surface layer of asphalt pavement is soft and sticky due to high temperature in summer. Under the action of vehicle load, the stress area is depressed, after the vehicle load is removed, the asphalt pavement can not completely restore the state before the load, that is, plastic deformation occurs. Under the action of repeated rolling of vehicles, plastic deformation accumulates continuously, which forms rutting, thus affecting the normal road traffic and bringing great potential safety hazards to the road. Therefore, in order to solve these problems, we specially analyze the structure of asphalt pavement, and summarize the main reasons for the formation of ruts, that is, because asphalt concrete has rheological properties under high temperature, and when subjected to load, only the pavement structure of asphalt concrete pavement can not restrain the plastic deformation of asphalt concrete aggregate, resulting in the movement of asphalt mixture, thus forming ruts.

In order to solve this problem, the glass fiber geogrid is used between the upper layer and the middle layer of the asphalt pavement, which can play a skeleton role in the asphalt pavement. The aggregate in asphalt concrete runs through the grids, forming a composite mechanical interlocking system, restricting aggregate movement, increasing the transverse binding force of asphalt mixture, and restraining each other in the asphalt surface layer, preventing the plastic deformation of the asphalt surface layer, thus playing a role in resisting high temperature rutting, which is of great help to the asphalt pavement.

As a professional manufacturer of fiberglass geogrid, our company provides ideal materials for the construction of asphalt pavement, and is well received by engineering units. It is a very good manufacturer of fiberglass geogrid, worthy of your purchase.
