Nonwoven geotextile fabric is manufactured from high quality polypropylene staple fibers by a needle punched treatment and thermal treated processed. Heat treated non woven geotextile fabric has the characteristics of good durability, high tensile strength and CBR puncture strength, adding more loading capacity and also have less shrinking volume in road constructions. The heat treated nwoven geotextile fabric can greatly increases its strength and reduces the possibility of rupture during application. In this case, filtration function takes place only in the transverse direction. Due to their high reinforcing properties, these types of materials are used in construction and land management. The non woven geotextile fabric acts as separator to prevent the intermixing of the different soil layer types, and as filter to allow the flow of fluids while preventing the passage of soil particles in road, railway, and drainage applications.
Issue
Increasing traffic pressures are causing varying degrees of cracking in Australian roads. This brings many additional road repair and maintenance costs. Asphalt road strain effect will make asphalt layer fatigue crack, the rain and so on will flow into the road surface, resulting in further deterioration of the situation. Crack reflection and permeation are also the main concern in road construction, which have become the design pain points in the process of road repair. Cost savings in road repair materials are also a key measure of design.
Solution
Nonwoven geotextile fabric is widely used in road surface maintenance because of its ability to separate materials of different mass, isolate and share loads or ribs with high tensile, puncture and anti-top breaking mechanics.
The use of nonwoven geotexNtile for asphalt layer stabilization provides better fatigue resistance, reduces the impact of ruts on the road surface, and reduces cracking by increasing shear resistance.
Road pavement asphalt using nonwoven geotextile mainly has the following functions:
- Maintenance of asphalt pavement;
- Prevents the old road surface reflective cracks and delays the occurrence and development of reflective cracks.
- Provide solidification of the road foundation for handling soft land base, improve the roadbed load capacity.
- Save more than 20% of material costs and extend the service life of the road more than 2 times.
The main functions details we can describe as follows:
- Soft soil stabilization. Geotextiles are used to provide effective separation of different granular fill in sub-grades. This can form a stabilized layer to control differential particles, reducing uneven settlement.
- Fierce competition and increasing cost. Nonwoven geotextile fabric the priority solution for base course reinforcement and subgrade stabilization. It has belew main functions including reinforcement, separation, filtration and Drainage. And the properties has been has been rigorously tested by independent third parties of Australia local NATA and American ASTM standard.
- Asphalt pavement reinforcement. Increased traffic pressure imposed more strains in asphalt pavements and bring the asphalt cracking and water penetration into the pavement. Geotextile avoid this issue in asphalt reinforcement with fatigue resistance and shear resistance. Geotextile provides a proved pavement reinforcement for retarding cracking and uneven deformation .
- Drainage water. Geotextile formed a drainage layer and provides the dimensional stability and field-proven structural strength for quick subsurface water drainage. The geotextile water flow property is the main feature of the drain due to its ability to rapidly collect and remove water. Compared with the pipe application, the geotextile can two direction strengthen the inflow capacity. And it’s also a method of cost effective installation in a narrow anchor trench in road bed and slope.
Benefits
The distinguished feature of geotextile High temperature resistance make it a perfect maeterial in asphalt mixture paving temperature of about 150 ℃. This condition requires the geotextile material can’t be shrink or melt at this temperature.
GEOSINCERE nonwoven geotextiles are made of polyester and have a high melting point of 230℃ and stable performance.
Also GEOSINCERE geotextile has high tear strength, fabric tensile strength is high and has the anti-aging resistance in the life of the road surface.
The good adsorption of geotextile fabric make it be a normal construction method when spray the asphalt bonding layer. The hot paving surface should absorb the glue under the fabric to saturate it and become dense with the bonding of the road surface.
Summary
To sum up, the GEOSINCERE nonwoven geotextile fabric has become an ideal geotechnical material in Australia Road constructions because of the perfect properties and the complete testing properties and be in accordance with the local NATA requirement.
