With the rapid development of ordinary highway, the reconstruction and widening of the old roadbed, the quality and life of the rebuilt subgrade have been paid more and more attention. Many questions such as the glass fiber geogrid can handle the cracks are widely used in the construction, but how the construction is accurate is a question, today the geotextile Xiaobian, a grille website, tells us about the countermeasures and proposals for the construction of fiberglass geogrids.
First of all, think from the planning. The goal of planning is to consider the extension of glass fiber geogrids and the target of photoaging. The study indicates that the contact point of glass fiber grille is made up, so the strength is much lower than that of its own data. When the force is applied, it will often slide. The strength of the tendon is actually the strength of the contact point rather than the strength of the reinforcement. Therefore, we should pay special attention to the value of reinforcement strength in planning. The elongation is the goal of controlling the reinforcement material to satisfy the engineering deformation request, and appropriately adjust the elongation rate of the fiberglass geogrid. In most cases, there are many pavement disposal plans after construction, and there are many types of pavement structure. Under the conditions of high temperature and climate change, there is an aging phenomenon under the conditions of high temperature and climate change, which is suitable for the glass fiber geogrid with high light aging target.
Secondly, it thinks from the construction technology. In the process of construction, we must organize the construction according to the construction plan strictly. Every process is assigned to a special person to check and control the construction of non-standard projects. The operation surface is ready, the old pavement level should be satisfied to ensure that the combination of the grille asphalt concrete overlay and the old pavement is outstanding. The old pavement should be cleaned before the spray coating oil is sprinkled. The glass fiber geogrid is laid on request. The glass fiber grille that has been damaged and posted is replaced. The grille is fixed on the iron sheet and fixed according to the fixed method requested. After laying, the rubber roller compactor is properly rolled to make it close. The grid is tightened to tighten the fiber glass. Strictly control the vehicle receipts and payments of the mixture, and prevent the vehicle from turning sharply in the grille. Emergency brake and dumping mixture material to prevent damage to glass fiber grille. The organization of the shop assists the truck's tires. About the working face of asphalt mixture in the future. The glassfiber geogrid, which is damaged due to roller compaction, should be replaced in time.
Finally, considering the improvement of the goods, some targets of the glass fiber grille are satisfied with the planning request and are not satisfied with the construction request, which affects the function of the road, because the geotextiles and the glass fiber grille have outstanding compressive mechanical properties, stable quality, can help delay reflection cracks, think with the features of Geotextiles and glass fiber grille. (excellent compressive mechanical characteristics and high temperature stability), composite data made of two kinds of data, that is, cover the geotextiles on the glass fiber grid, show the advantages of the two, and together form a isolation layer between the transport vehicle and the glass fiber geogrid. In view of the above factors, we can think about the improvement of the commodity essence of the glass fiber geogrid, so that it can satisfy the construction request and cover a layer of plastic film on the glass fiber grid. Under the high temperature effect of the asphalt mixture, the plastic film is immediately ablated and does not constitute the interlayer. The isolation layer between the truck tire and the glass fiber grille can effectively prevent the damage of the conveying truck to the glass fiber grille.
