Description:

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 .

Application

Filtration

It can be the filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.

Separation
