High performance polyester spunbond

?

?

Specifications:

?

polyester spunbond is installed in the bitumen layer of the road, providing a stress alleviating and waterproofing function that prevents pavement cracking. It doubles the life of new asphalt overlays.


1. conform to ?the requirement ?of designing?
2. revent crack
Main behavior is absorbing and elimination of stress. Especially prevent the crack which cause by temperature and sedimentation .
3. revent and cure rut?

Our product is reinforcement effect . it resist the plastic deformation of road?
4. prevent the damage of water from surface?
After combine the bitumen , it will be stable waterproof which prevent the water falling down effectively .
5. high construction quality?

Description:

?

The main reason of above disease is as follows:

1. expand with heat and contract with cold because the temperature?
2. ageing of bitumen and elasticity decline of surfacing?
3. substrate has crack and horizontal fall head?
4. material which used and construction method ,etc?

?

According to the cracking of bitumen concrete road ,when we add the surface on the before road or semi-rigid surface , we can use the high performance polyester spunbond between new surfacing and old surfacing , then we can prevent above disease .

ROADS

Road crack prevention & extended use

When surface cracks appear on roads, moisture penetration can cause the road base to fail. It paving fabrics extend the life of the road pavement by providing a waterproof, stress-relieving membrane between the old and new surfaces.

Road reconstruction with cement treated bases

Roads with cement bases can crack due to shrinkage, thermal effects and fatigue. It paving fabrics work by reinforcing the surface, limiting reflective cracking and waterproofing the surface seal.

Crack prevention in asphaltic pavement overlays

When saturated with bitumen It seals the existing pavement and reinforces the surface. It can be used on localised crack sealing or patching as well as full-width resealing. It can be manufactured to suit your specific needs and is available in a range of widths.

Low volume roads

Because It paving fabrics can be used directly over the pavement formation, local materials can be used which saves on haulage costs.
