Pavement Rehabilitation Geotextile

Pavement Rehabilitation Geotextile

Ⅰ. Product Introduction

Pavement rehabilitation geotextile is a professional needle-punched nonwoven geosynthetic material, primarily produced from polyester or polypropylene fibers. It is tailor-made for old road reconstruction, pavement renovation and surface overlay projects. As a key auxiliary material for road maintenance, it solves common pavement diseases such as reflection cracks, water damage and uneven settlement, and effectively restores and improves road service performance.

Ⅱ. Main Functions

1. Anti-reflection Cracking

Absorb and disperse stress from original pavement cracks and joints, block cracks from spreading to the new overlay layer, the most vital function for old road renovation.

2. Separation

Separate subgrade soil, base course aggregate and asphalt layer, prevent intermixing of different materials and maintain the stability of pavement structure.

3. Filtration & Drainage

Permit water to drain out while retaining fine soil particles, avoid subgrade softening, erosion and water-induced damage.

4. Reinforcement & Stress Distribution

Uniformly disperse vehicle loads, reduce rutting and differential settlement, enhance the overall bearing capacity and structural durability of the pavement.

Ⅲ. Application Scenarios

·Asphalt overlay on original cement concrete pavement

·Renovation of aged, cracked and rutted asphalt roads

·Expressways, municipal roads, rural highways rehabilitation projects

·Airport runways, parking lots and bridge deck pavement renovation

Ⅳ. Product Advantages

·Significantly extend pavement service life and reduce later maintenance frequency

·Lightweight, flexible, easy to cut and lay, shorten construction period

·Excellent anti-aging, corrosion and UV resistance, long service life

·Low comprehensive investment, remarkable economic benefits for road projects
