The main functions of nonwoven geotextile separation fabric are filtration and separation, the most common used nonwoven geotextile separation fabric needle punched geotextile which is made from staple fibers or continuous filaments bonded by mechanically entangling the fibers with barbed needles. It looks and feels like felt. Although non woven geotextile has a lower tensile strength than the woven type, it still offers great strength, durability and excellent drainage properties. This type of geotextile separation fabric is easier to cut, has a high water permeability rate and does not lose strength over time, in the same way as the woven fabric does, when used below ground. The nonwoven geotextile separation fabric is the ideal geotechnical product for road or pavement restoration project.
A considerable part of the existing cement concrete pavement is close to or has exceeded the design life due to the rapid increase in traffic volume, the increasing overload of automobiles and the design and construction reasons, the road damage is becoming more and more serious, which affects the use function of the road. As a typical modification measure, the asphalt concrete surface layer is added on the old cement concrete pavement, which is generally adopted by the old road reconstruction projects in various countries around the world. However, the added asphalt cracks often appear in the paved asphalt concrete, which will greatly affect the service life of the overlay. Recent studies have shown that the use of geotextile separation fabric is an effective and economical method to slow the reflection cracking of asphalt overlays.
BPM Phillipine client is a Manila construction contractor that undertook the renovation of a cement concrete pavement project that has been in use for more than a decade. In order to solve the problem of road surface failure, faulty platform and bottom plate void, and thoroughly improve the quality of road conditions, the engineering transformation plan of asphalt concrete surface layer was adopted, and the application of geotextile separation fabric was researched and explored. The overlaying scheme is designed to take modified asphalt concrete and special 500gsm needle punched non woven geotextile, which can achieve the effect of road surface reinforcement to increases the service life, and can reduce the engineering difficulty and reduces the engineering cost at the same time.
Specifications of Geotextile Separation Fabric for Pavement Restoration Project in Philippine
- The geotextile separation fabric can reduce the bonding force between the overlay and the old pavement layer.
- Because the geotextile has high strength and large extensibility, the geotextile separation layer can play the role of stress absorption interlayer.
- Anti-seepage effect.
- The nonwoven geotextile can reduce the tensile stress under load.
