Ⅰ.Product Introduction
The fiberglass geogrid is a new type of base material for the civil engineering of road. It is made of high-quality reinforced alkali free fiberglass yarn and formed by using advanced warp-knitting machine imported from abroad. The product has excellent alkali resistance after surface coating treatment. The use of the fiberglass geogrid can effectively improve the stress distribution of road structure, resist and delay the occurrence of reflection cracks caused by cracks in road base layer, thus improving the service life of road. Compared with the traditional road, this material can reduce the cost and prolong the service life of roads. This material is generally used for the reinforcement of the new road and the maintenance of the old road to prevent the occurrence of reflective cracks. The reinforcement treatment of soft-soil roadbed can promote the consolidation of soft soil and the bearing capacity of soil roadbed by using this product.
Ⅱ.Product Characteristics
The product has excellent characteristics, including high tensile strength, low stretch rate, high elastic modulus, high temperature resistance, no long-term creep, stable physical and chemical properties, fatigue cracking resistance, high-temperature rutting resistance, low-temperature shrinkage crack resistance, delay and reduction of reflection cracks, and good compatibility with asphalt mixture, etc. It can be widely used in asphalt road, cement concrete road and roadbed strengthening, regardless of hard or flexible road. Compared with the traditional road, it can extend the service life of roads, reduce the maintenance cost and maintenance frequency, save the engineering cost, prevent the reflection of cracks and cracks on the road surface, etc. The product can also be used for railway, airport, irrigation works, strengthening of embankment and other soft soils， and road base strengthening，etc.
Ⅲ.Product Uses
1. Due to the old asphalt concrete road appears serious cracking, the product can reinforce and strengthen new asphalt surface to prevent and handle damage;
2. The product can reconstruct cement concrete road to compound road so as to inhibit board shrinkage and reflection cracks;
3. The product is used in the road extension and reform project to prevent cracks caused by new and old joints and differential settlement;
。
4. The product is applied when the semi-rigid base course of new roads produces shrinkage cracks. It can reinforce and strengthen base so that this can prevent the reflection of cracks in the base from causing pavement cracks.
