Polyester Fiber ( PET )

                                                      --------- Bitumen Concrete Reinforced Fiber

PROPERTIES:

 1. After the po1ypropylene fiber successfully used into the cement concrete , polyester fiber is a new-developed engineering material in recent years. With polyester as its raw material, the fiber is produced through adding some functional additive, by plastic melting, extruding, high-ratio stretching and special surface disposal. And shaped by cutting with special machine Its appearance is beam-like structure with many monofilament fiber collecting.

2. Besides the small thinness, high tensile strength and easily scattering, polyester has good heat-resistance. It can be used in hot-mixing bitumen concrete projects and reinforced crack-resistance for high-tensile concrete, so it is an ideal multi-functional reinforced material.

3. According to the testing report by  many authorized organizations, the polyester fiber's main technological performance indexes all reach the advanced level of the same products in the world.

APPLICATIONS:
1. function:

Prevent ear1y crack of concrete and effectively resist reflection crack   Prolong the life span

Increase the crack-resistance in low temperature            Increase the fatigue-resistance

Improve the flexibility , seepage-resistance, wear-resistance and stability in water  

Improve the stability in high temperature.

2. Suitable area and add amount:

A). New built bitumen road: 

B). Recovery of old bitumen road layer.    

C). Repair of old cement road layer.         

D). Defect maintenance of road surface.      

E). Reinforced crack-resistance of fine aggregate high-tensile concrete project. 

3. added amount:

A). Applied for High-grade Road , Transportation day & night, added amount

(kg/per ton bitumen mixture)

<3200     1.2

3200-85000   2.3

>85000    3.5

Note: If there are more heavy vehicles, the added amount should be improved one grade.

B). Applied for Paving Bridge

Wear layer         3.5kg/one ton bitumen mixture

Air membrane layer 2.3kg/one ton bitumen mixture

4. Feeding and technical processing

Put aggregate and polyester fiber into the mixer together,and stir 30s without water,

then put bitumen stirring  for 30s with water in order to make them  mixing completely.
