What is the action mechanism of OKorder geogrid
Glass fiber geogrid / glass fiber grille with glass fiber rovings as main raw materials, the reticular structure material of the knitting process, for the protection of glass fiber, improve the overall performance, through a special coating treatment process and the formation of new excellent geotechnical materials. Glass fiber has high heat resistance and excellent cold resistance, high strength, high modulus, good chemical stability, corrosion resistance, low coefficient of expansion, good dimensional stability and so on
Glass fiber geogrid / glassgrid mechanism of reflective cracking is due to the old concrete surface layer in the vicinity of the joint or crack of large displacement caused by the asphalt overlay above appear stress concentration caused by the. Glass fiber geogrid has been developed rapidly in recent years, and is widely used in asphalt pavement, especially used in asphalt overlay to reduce reflection cracks. Texas Traffic College of AM University in Canada with its unique overlay tester of glass fiber geogrid reinforced cover did a lot of tests and experiments show that the reinforced asphalt specimen cracking resistance than the unreinforced specimens two times. Wollongong Municipal Bureau of New South Wales, Australia has conducted on-site tests of glass fiber geogrid, PP geogrid, geotextile and thickness of asphalt concrete surface layer of reflection crack control products, the conclusion is glass fiber geogrid laying convenience, control effect of reflection crack is the most significant, and the cost is moderate. Therefore we should promote the application. Due to the reinforcement effect of glass fiber geogrid on asphalt overlay, so it can be in the premise of effective control of reflection cracks, reduce the asphalt overlay thickness (with and without laying fiberglass geogrid, compared) reduce the cost, and achieved good economic benefit.
After surface modification and coating treatment, the surface properties of the glass fiber were changed, and the composite performance of the fiber was improved. Glass fiber geogrid has the above characteristics, it can play an important role in the following aspects.
