It is made by coating glass fiber geogrid with self sensing adhesive. On the basis of maintaining the characteristics and functions of glass fiber geogrid, the grid and contact surface layer are tightly combined, which has the characteristics of convenient construction and smooth paving. It is particularly suitable for reinforcement and strengthening in highway construction, pavement reinforcement, old road reconstruction and other projects.

Fiberglass geogrid is a new and excellent geotextile substrate for enhancing road surfaces and roadbeds. The product is mainly made of alkali free glass fiber filaments, woven using a unique warp knitting and weaving process, and coated with special adhesive to form a mesh structure material. It can effectively improve the stress distribution of road structures, resist and delay the occurrence of reflection cracks caused by base cracks, improve the service life of roads, reduce costs, and improve construction quality

Application features:

1、 The extension coefficient of fatigue life for highways reinforced with this material is 4-7 years, assuming the same thickness as the unreinforced asphalt layer.

2、 When the entire asphalt concrete highway is built on a relatively weak foundation, using a layer of geogrid can save 50-100mm thick high-quality asphalt concrete.

3、 It can effectively control, delay and prevent the occurrence of cracking caused by low temperature and reflection cracks caused by cracks in the foundation layer. The minimum thickness for effectively reinforcing asphalt concrete with fiberglass geogrid reinforcement material is 40mm. The geogrid should be placed at the bottom of this layer of asphalt concrete.

4、 The use of fiberglass geogrid on asphalt pavement can reduce ruts by more than 50%.

5、 Add an asphalt concrete layer to the severely cracked asphalt concrete pavement in the maintenance system; Laying asphalt concrete layer on rigid concrete pavement; Add an asphalt concrete layer on top of the semi-rigid foundation layer. The above three types of road surface overlay layers are reinforced with fiberglass geogrids and asphalt concrete, which can effectively prevent and delay the occurrence of reflective cracks, quickly absorb and diffuse stress caused by gravity, reduce project costs, extend service life, and lower maintenance costs.

6、40mm The strength of thick fiberglass geogrid reinforced asphalt concrete surface layer is equivalent to the strength of 100mm to 175mm (4-7 inches) thick asphalt concrete surface layer without fiberglass geogrid reinforcement.

Direct laying method:

A、 Spray AH-70 or AH-90 heavy oil hot asphalt, with a recommended dosage of 0.3kg-0.4kg/square meter

B、 Use old asphalt concrete pavement and old cement concrete pavement to make a leveling layer with a thickness of 20mm to 30mm, and use a vacuum truck or sprinkler truck to ensure that the road surface is clean.

C、 Special paving vehicles are used to lay self-adhesive fiberglass grids, which should be laid smoothly and tightly.

D、 The horizontal overlap length should be 50mm~100mm, and the vertical overlap length should be 150mm~200mm. The overlap direction should be consistent with the direction of operation of the asphalt concrete paver.

E、 Use a rubber roller to roll (the rubber roller needs to have a sprinkler device), measure and cover the surface.
