Feicheng Lianyi Engineering Plastics Co., Ltd. is one of the most experienced manufacturers and suppliers of asphalt grid in China. Please feel free to buy high quality asphalt grid at competitive price from our factory. Welcome to view our website for more information.
Product Introduction:
Asphalt grid is made from high-modulus fiberglass yarns and coated with bitumen to achieve a good bond to the asphalt.
Therefore asphalt grid provides an effective method of preventing reflective cracking in asphalt layers. This advantage applies in cold, temperate and hot climate zones.A road reinforced with suitably designed and properly installed asphalt grid reinforcement will remain crack-free for many years.
Properties:
• High temperature stability
• Elongation characteristics match the modulus of the asphalt
• Long-term dynamic load-carrying capability
• Good bonding characteristics with asphalt

Asphalt grid installation
Strengthened net is rolled out either by hand or machine. Asphalt grid installation does not require a special net tighten or other measures, therefore, it´s quicker and easier to install than other nets.
Using asphalt grid you should know the following:
Avoid wrinkling wave changes of the net. Light wave in front of asphalt machine does not affect the net function. Follow-up of asphalt should not hold out with overhanging grid. Make sure the surface is clean before spraying bitumen.
The reinforced layer of compaction should be carried out with lightweight or moderate gritter or rubber-tyred road roller. Heavy roller is used for the final compress. Vibration system´s use in case of thinner than 80 mm layer, it is not recommended.
