Asphalt fibers for pavement reinforement mainly consist of polyacrylonitrile fibers, polyester fibers, hybrid aramid fibers, lignin fibers (lignin fibers are further divided into flocculent lignin fibers and granular lignin fibers), etc., which play a role in crack resistance, adsorption, dispersion, and improving the high and low temperature stability of asphalt to enhance its strength.
Function of asphalt fibers in asphalt concrete
Improve the high-temperature stability of asphalt concrete
Improving the low-temperature crack resistance of asphalt concrete
Improving the fatigue resistance of asphalt concrete
It can significantly improve the water stability, anti stripping, wear resistance, and durability of asphalt concrete, effectively resist the generation of reflective cracks, thereby greatly improving the quality of the road surface and extending its service life
Can effectively improve tensile, compressive, shear, and impact strength.
Application of asphalt fibers
New asphalt concrete pavement surface layer
Old asphalt concrete pavement overlay (black+black)
Old cement concrete pavement overlay (white+black)
Defect repair, cold repair, and crack filling on the road surface
Asphalt surface layer for steel structure bridge paving
Airport runway and bridge deck waterproof layer
