To mitigate uneven settlement at the junction of the new and old roads, this project installs reinforcement mesh between the subgrade and sub-subgrade at the junction (specific location shown in the road design drawings).
Reinforcement mesh is made from a double twisted metal mesh surface, with transverse reinforcing bars woven into the mesh at an approximate spacing of 16cm. The roll length of the road reinforcement mesh is 25m, with a roll width of 3-4m, and the length and width can be customized as desired. Galvanized steel wire products are used to prevent corrosion of the road reinforcement mesh.
Key Performance:
As a new type of reinforcing material for metallic road surfaces, wire mesh optimally utilizes its high tensile strength and low strain, along with the interlocking action of the mesh surface and aggregates. It absorbs existing cracks and tensile stresses generated by traffic loads, delaying crack propagation, reducing bending deformation, and enhancing the road surface's resistance to reflective, thermal, and fatigue cracks. Simultaneously, it effectively reduces the rutting and drift effects caused by vehicle loads, strengthening the road surface's bearing capacity. This, in turn, improves the road's condition and extends its service life. The wire mesh forms an open three-dimensional structure, interlocking with asphalt aggregate bases to prevent the formation of soft sandwich layers. This interlocking promotes load transfer to the reinforcing structure, distributes stress, and increases the road surface's fatigue life. Each wire is combined with surrounding asphalt to form a cohesive unit, composed of approximately 95% asphalt mixture, functioning as a continuous aggregate base with aggregate stones, effectively exhibiting its tensile and crack-preventing properties. The wire mesh features low creep, providing its tensile strength instantly when the road structure is under tension, preventing cracking caused by creep.
