The geogrid with bitumen coating acts as a barrier, preventing the cracks from propagating to the surface. This helps to maintain the integrity of the overlay and prolong its lifespan.
Furthermore, polyester geogrid with bitumen coating can also enhance the stability of the asphalt pavement. The geogrid helps to distribute the load more evenly, reducing the risk of rutting and deformation. This is particularly important in areas with heavy traffic or in parking lots where vehicles are parked for extended periods. By improving the stability of the pavement, the geogrid with bitumen coating helps to ensure a smoother and safer driving experience.
In addition to these benefits, polyester geogrid with bitumen coating is also easy to install. It can be rolled out and placed directly on top of the asphalt layer, without the need for any additional adhesives or equipment. This makes it a cost-effective solution for improving the durability of asphalt pavements.
In conclusion, the use of polyester geogrid with bitumen coating offers numerous benefits in terms of improving the durability of asphalt. It increases the tensile strength, enhances fatigue resistance, improves resistance to reflective cracking, and enhances stability. Additionally, it is easy to install, making it a cost-effective solution for construction projects. By incorporating polyester geogrid with bitumen coating into asphalt pavements, contractors can ensure longer-lasting and more resilient road surfaces.
