Rangdaneh Kortta ParaFiber
The Rangdaneh Kortta ParaFiber has been Registration in State Organization for Registration of Deeds and Properties (Intellectual Property Center)
It creates more durable procedures that increase the life of the pavement. The asphalt reinforced with these fibers has a higher tensile and modulus resistance and provides better resistance to the asphalt of the control against fatigue cracks, grooves and creep.
These composite fibers in the form of microfiber and powder fibers or bitumen modifiers can be used in asphalt pavements.
Technical properties
Specific gravity (gr/cm3) : 1.1 to 2.7
Length (mm) : 6-19
Diameter (mm) : 0.5-12
Color : white - yellow
Melt point (°c) : 140-230-450-550
Tensile strength (MPa): 750-1100
Water absorption : No
All the above specifications are based on the design of asphalt mix, weather conditions, traffic load and other items in the form of a screw version.
Production and execution
1- Fiber should be added to the mixer at the same time as the stone materials from the weighing and must be before adding bitumen.
2- The mixing time of stone materials, fibers and bitumen in the mixer is determined at least 40 to 60 seconds.
3. There should be full coordination and planning between the stages of production, transportation, distribution and crushing of fiber asphalt, so that the set of executive operations is carried out continuously and without interruption, and there should be full supervision in implementation.
5- Avoid stopping the players and rollers during the separate operation, because it causes unevenness of the asphalt surface and full supervision must be done.
6- Rolling operation should start immediately after the asphalt spread and the rollers should have the shortest distance with the spreader.
7- Dosage: 1 to 2 kg of fiber per ton of asphalt
