Highway 1A, the road leading to the Tra Khuc bridge (Quang Ngai), has a large vehicle load, high load caused cracking surface, the blockage is relatively large. To overcome this situation, the Road Administration III decided to apply the new material, fiberglass geogrid GlasGrid (USA). The construction process is in accordance with the manufacturer's procedures, carried out by the Quang Ngai Road Management and Construction Company under the guidance of technical staff from AT & T and the representative consultant. Da Nang Bridge Science Association.

GlasGrid fiberglass geogrids are characterized by self adhesive, activated under the pressure of the iron wheel, creating a solid bond with the asphalt layers. In addition, with other high strength parameters such as: tensile strength (bilateral) of 115 kN / m, elongation of 2.5%, elastic modulus E of 73,000 MPa, melting temperature and at the joints 232 and 820 degrees Celsius respectively, GlasGrid assures excellent quality in the geotextile product line.

In addition, with more than 25 years of production and development experience of the Saint-Gobain Group, many successful applications in the world and in Vietnam, geotechnical fiberglass reinforced mesh promising The optimal choice for investors in solving the problem of cracking is very popular on the road system of Vietnam today.

AT & T is the official representative for distribution and technology transfer of this product line in Vietnam.
