Product introduction: polyester fiber is dedicated to strengthen the fiber asphalt concrete product, its material is 100% modified polyester.Fibers were treated with uv protection, has the strong ability of anti-aging.Day grace polyester fiber can obviously improve the asphalt surface bonding, high temperature stability, fatigue durability, and has the performance of the low temperature crack resistance and prevent the reflection crack.Fiber after surface treatment at the same time, can be uniformly distributed in the asphalt concrete, and asphalt concrete links closely, have very good reinforcement effect.Day diet, therefore, dedicated to enhance fiber is widely used in bridge pavement of asphalt pavement, road surface, such as toll station in asphalt concrete pavement

Main functions: to improve the high temperature stability of asphalt concrete
To improve the low temperature cracking of asphalt concrete, tensile and shear properties
Play a strong role, increase the toughness of concrete
To improve the water stability of asphalt concrete performance and fatigue resistance, anti-aging, increase the service life
Application: apply to new and old asphalt concrete pavement overlay
Bridge deck paving asphalt concrete abrasion, gas membrane layer
Old asphalt pavement and cement road surface thin layer asphalt concrete surface
The strengthening of the airport runway and apron
Pavement reinforcement and repair, and keep strengthening

Appliction:used for bridge deck pavement wearing layer: 3.5 kg/ton asphalt mixture gas film layer: 2.5 kg/tons of asphalt mixture
Construction technology: using days grace polyester fiber, asphalt mixture mixing ratio basically remain unchanged, just put the oil-stone ratio 0.2% increase;Day grace polyester fiber should be used according to the production of every plate of the mixture of the quantity of packing, do not need to open the packaging, when using directly in proportion to join, convenient and safe;
Construction technology and no added fiber basic same, as long as fiber and aggregate join mixer at the same time, to do with 25 to 30 seconds, then wet mix 30 seconds.Mixture mixing evenly, the fiber asphalt mixture and wrapped by good shall prevail;
Paving equipment for ordinary crush, don't add other equipment.
