Dedicated high-performance polyester fiber works of asphalt concrete I. Overview of polyester fiber engineering
Hengtai for high-performance polyester fiber is a kind of enhanced cracking of asphalt concrete fiber, which is the main raw material of polyester,
Add some functional masterbatch, by Melting, extrusion, high-speed spinning, high-magnification stretching, with a special surface treatment, cut off from its appearance as a single wire bundle.
Polyester has high strength, chemical stability, and asphalt absorption and strong, easily dispersed, not agglomerate, high temperature,
Low temperature resistance, etc., can be used in hot mix asphalt concrete, can also be applied to enhance the crack resistance of high strength concrete. Detected by the domestic authorities, Hengtai main technical performance polyester fiber reached the advanced level of similar foreign products.
Second, the polyester fiber engineering parameters;

Third, the polyester fiber function works
● to improve the high temperature stability of asphalt concrete, cold crack resistance
● to improve the flexibility of asphalt concrete, peel resistance, wear resistance.
● to improve the fatigue properties of asphalt concrete to extend the service life of asphalt pavement
Fourth, the main purpose
● new asphalt concrete pavement surface
● Old Asphalt Concrete Pavement Overlay
● New and Old Concrete Pavement Overlay
● surface defect repair
● airport runway
● Deck
Fifth, polyester fiber works Help
Size and traffic load under different selection Hengtai fiber content. General traffic the greater the load the greater the fiber
Higher-dimensional content, the proposed fiber per ton of asphalt content is:
Day and night traffic (number of) content (kg)
3000 the following 1-2
More than 3000 2-3
More heavy vehicles, the dosage should be increased by one grade.
Mix design and mixing temperature: do not change the mixture ratio of raw materials, without changing the mixing temperature.
Construction Technology: polyester fiber and aggregate will join mixer, the first 30 seconds of dry mix, then add the wet asphalt mix for 30 seconds to ensure uniform dispersion fiber as possible.
Forming and maintenance: no special requirements, no additional ancillary equipment.
VI-benefit analysis of polyester fiber works:
★ tensile strength, compressive strength increased substantially.
★ improve the oil pan, such as asphalt content the same, the porosity increased by 38%, help to improve the thermal stability of asphalt concrete.
★ can greatly reduce the surface reflection of cracks and shrinkage stress temperature, impact and destruction caused by cracking.
★ greatly improve the road adhesion, stability, rheology, abrasion resistance, effectively improve the tensile, shear, compression and impact strength, can improve the crack resistance of the road, greatly improving the quality of road surface, the effective extend the pavement life.
★ Fiber by UV treatment, has strong anti-aging ability, and the material itself that is strong acid and alkali resistance ability, it is durable and reliable.
From the above analysis, the use of special polyester fiber asphalt concrete pavement overlay projects with highly visible and social benefits, a small investment and long-term benefit, in particular, save a lot of maintenance cost, comprehensive benefits are obvious, for road construction extremely important.
