High performance polyester spunbond

Description:

Traffic safety of bitumen road is most decided by the condition of bitumen road , many investigation show that :common disease of bitumen concrete road is crack ,rut and basic softening .if we prevent above disease effective,it will be more safety and comfortable for driving 

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 .

Performance and mechanism of action of high performance polyester spunbond 

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