The Significant Role of Guangdong Fiberglass Geogrids in Old Road Reconstruction

2020-10-19


As urbanization progresses, it inevitably leads to the integration, replacement, and renovation of old and new infrastructure in cities. For urban roads, particularly at the junctions between existing and newly constructed roadbeds, careful attention must be paid to the roadbed and pavement. A key solution for handling these transition zones involves addressing three critical aspects: ensuring the foundation remains strong and stable; guaranteeing high-quality compaction of the newly filled soil; and fostering a seamless bond between the fresh fill and the compacted old roadbed. Successfully resolving these three issues typically ensures that the road maintains superior quality at the interface between the old and new roadbeds.

Additionally, during spring and summer, soil particles in the foundation tend to become saturated with water, while in winter's cold temperatures, they are prone to frost heave. This variability in bearing capacity caused by weak foundations can also significantly damage the joints, potentially leading to cracking and settlement of structures built atop them. As a result, the roadbed may develop large-scale, wave-like deformations—both transverse and longitudinal—which can cause pavement distortion or cracking. Consequently, this places even higher demands on the construction techniques used for roadbed jointing and splicing.

Hubei Xianning Fiberglass Geogrid , especially in highway and urban road projects. The three pavement overlay types mentioned above are used: Hubei Xianning Fiberglass Geogrid Strengthening asphalt concrete can effectively prevent and delay the formation of reflective cracks, while also quickly absorbing and dissipating stresses caused by gravity, ultimately reducing project costs.

The grates in existing technologies are typically woven from metal wires of varying specifications, making them complex to produce. They lack impact resistance and tend to deform or rust over time, leading to high costs. As a result, they are usually limited to use in fencing applications and cannot be employed in highway or urban road projects.

Compared to existing technologies, Hubei Xianning Fiberglass Geogrid It features excellent dimensional stability, impact resistance, corrosion resistance, low cost, and lightweight design, making it easy to handle and use. Primarily used in highway and urban road construction, it is also ideal for applications such as fencing, railway projects, water conservancy systems, port slope protection and maintenance, desert control, and geotechnical engineering.

Hubei Xianning Fiberglass Geogrid It is a new, high-performance geosynthetic material designed to strengthen road surfaces and subgrades, manufactured by weaving and coating glass fiber filaments. Hubei Xianning Fiberglass Geogrid Featuring high tensile strength in both longitudinal and transverse directions, low elongation, a high modulus of elasticity, and excellent resistance to both high and low temperatures, this material—when surface-coated—also exhibits outstanding alkali resistance and superior aging durability. It is widely used to reinforce asphalt pavements, cement concrete surfaces, and road subbases. Suitable for both rigid and flexible pavements, it helps reduce construction costs, extend service life, and effectively prevent reflective cracking compared to conventional pavement solutions. Hubei Xianning Fiberglass Geogrid It can also be used to reinforce soft soils in railways, airports, water conservancy projects, embankments, and for strengthening road bases.

Hubei Xianning Fiberglass Geogrid The material exhibits stable physicochemical properties, boasting high strength, superior modulus, excellent abrasion resistance, and outstanding cold-weather performance—plus, it shows no long-term creep. It also demonstrates excellent thermal stability. Its unique network structure enhances aggregate interlocking and confinement, significantly boosting the load-bearing capacity of asphalt mixtures. Additionally, a special modified asphalt coating on its surface imparts dual-layered composite properties, dramatically improving both the abrasion resistance and shear strength of the geogrid.
