Road Reinforcement Mesh is a deep-processed form based on Gabion Mesh, with its production principle being that during the weaving of heavy-duty hexagonal mesh on a hexagonal mesh machine, a transverse reinforcing rod is inserted and twisted through the center of the wire at an interval of 16 centimeters. It features high tensile strength of the mesh and high elongation at yield of the mesh. Road Reinforcement Mesh is generally woven from zinc-aluminum alloy wire or hot-dipped galvanized wire with high corrosion resistance, with the diameter of the reinforcing wire not less than that of the edge wire, most commonly being 3.4mm, 3.2mm, and the mesh size internationally used is 80.100 mesh, finished product is transported in rolls, typically with a width of 3-4 meters. Due to the repetitive production process and low daily output, the reinforced road mesh is also more expensive compared to regular stone笼 net!
Road Reinforcement Mesh Structure: The steel wire mesh is made of high-strength, ductile steel wire, which is hot-dipped galvanized or hot-dipped Galfan for corrosion resistance. It features a mechanically woven double twisted hexagonal mesh structure. Common specifications include a mesh size of 8cm x 10cm with wire diameters of 2.0mm to 2.7mm. The transverse reinforcing wires are made of the same material as the mesh wires but thicker, inserted at a 16cm spacing (adding a reinforcing wire every other mesh). To facilitate construction, the steel wire mesh is often supplied in rolls from 1 meter to 4 meters wide and 50 meters long. They are rolled and packaged for direct laying on construction sites. The width and length of the mesh can be cut to size as needed either at the factory or on-site.
Road Reinforcement Mesh Function: It is designed to reduce the reflective cracking issues caused by uneven settlement of old and new subgrades during road reconstruction and expansion. Laying a metal reinforcement mesh on the asphalt sublayer at the junction of old and new subgrades can effectively reduce the likelihood of longitudinal cracks in asphalt pavements. This metal reinforcement mesh is known as road reinforcement mesh, double twisted road reinforcement mesh, road reinforcement mesh, reinforced gabion mesh, highway reinforcement mesh, road metal mesh, etc. The double twisted steel wire mesh employs a unique bidirectional load-enhanced three-dimensional structure, featuring high modulus, high strength, low creep, and resistance to brittle cracking. The purpose of laying steel wire mesh between the subgrade and surface layer at the junction of old and new roads is to allow the asphalt mixture to wrap around and interlock with the steel wire mesh, quickly and accurately transferring the stress from asphalt aggregates to the reinforcement layer. This aims to reduce pavement rutting cracks and reflective cracks, decrease uneven settlement of old and new subgrades, and extend the service life of the road.
Road Reinforcement Mesh Application: Primarily used in road widening and asphalt pavement construction projects, the road reinforcement mesh is applied by overlaying it to enhance pavement bearing capacity with minimal investment. In road widening projects, it effectively resists differential settlement cracks caused by uneven differences in the new and old subgrade surfaces, delays crack propagation, reduces bending deformation, and improves the pavement's resistance to reflective, temperature, and fatigue cracks. It also effectively reduces rutting and creep effects caused by vehicle loads, enhancing the pavement's bearing capacity. Consequently, it improves the pavement's condition and extends its service life.
