Crack-resistant mesh extends the service life of road infrastructure.

Road and site hardening projects, including asphalt pavement, are constantly affected by vehicle loads, temperature variations, and soil settlement. The surface layer is highly susceptible to surface cracks, longitudinal cracks, and reflective cracks, which not only affect driving comfort but also allow rainwater to seep into the roadbed, causing soil softening and pavement collapse, significantly shortening the road's service life. Crack-resistant mesh, as a new type of reinforcement material, inhibits pavement cracking at the structural level, becoming a standard material for road maintenance and new road construction. Early road damage treatment relied solely on surface asphalt repairs, failing to address the root cause of underlying stress cracking. Cracks would quickly re-spread after repair, leading to repeated repairs and increased maintenance costs. Steel mesh reinforcement solutions were too heavy, resulting in high transportation and installation costs, and the steel bars were prone to corrosion and expansion, which could actually exacerbate pavement damage.

Crack-resistant netting comes in two main categories: fiberglass and plastic. Fiberglass crack-resistant netting has a high modulus and high temperature resistance, making it suitable for hot asphalt paving. It won't soften or deform during high-temperature asphalt pouring, evenly distributing pavement temperature stress and preventing cracks in the underlying soil from reflecting upwards to the asphalt surface. Plastic geotextile crack-resistant netting is tough and corrosion-resistant, suitable for cement concrete pavements and rural hardened roads. It resists tensile stress caused by soil settlement, preventing concrete slab cracking. The material's mesh structure forms a stable and reinforced framework, laid between the base and surface layers, evenly distributing concentrated loads over a larger area, reducing localized stress concentration on the pavement, and minimizing crack formation at the source.

Besides road engineering, crack-resistant netting can also be used for plaza hardening, parking lots, factory floors, and embankment surface protection. After laying a cement surface layer, the mesh constrains concrete shrinkage deformation, reducing thermal shrinkage cracks. When used in conjunction with shotcrete slope protection, crack-resistant netting improves the integrity of the shotcrete layer, preventing mortar detachment and cracking on the slope. The material is corrosion-resistant and rust-free, and its performance will not degrade even after being buried inside the road surface for decades. The lightweight roll material is easy to transport, and on-site cutting and laying requires no heavy equipment, resulting in construction efficiency far exceeding that of steel mesh and a significant reduction in overall project costs.

In road maintenance and renovation projects, adding anti-crack mesh during the milling and repaving of old road surfaces can significantly delay the recurrence of cracks, extend the road overhaul cycle, and reduce traffic congestion and resource consumption caused by repeated excavation and construction. The industry continues to upgrade mesh weaving technology, optimizing mesh aperture and tensile strength specifications, and launching differentiated products for heavy-load national highways, light-load rural roads, and scenic walkways, adapting to different load levels. Currently, the infrastructure industry is vigorously promoting long-term and durable road construction standards. With its low cost, high durability, and ease of construction, anti-crack mesh is widely used in various hardened road surface projects, effectively reducing the overall life-cycle maintenance costs of roads and contributing to the green and long-term development of transportation infrastructure.
