- Abstract
In order to solve the safety problem of snow and ice on the road in winter, and at the same time to make up for the excessive amount of carbon fiber agglomeration defects, carbon nanotubes-carbon fiber preparation of conductive asphalt mixture, electrical heating and fracture test, analysis of carbon nanotubes in different doping levels of asphalt mixture electrical heating and fracture resistance were conducted. The results show that carbon nanotubes/carbon fiber asphalt mixture resistivity exponential function decreases with the increase of carbon nanotubes doping. When the amount of carbon nanotubes is 0.5%, the heating effect is the best, and it only takes 5 min for the mixture to rise from-10 ℃ to 0 ℃. The heating effect is improved by 37.5% in time. The appropriate amount of carbon nanotubes can improve the cracking strength and bending and tensile strain of the asphalt mixture, and enhance its toughness, macroscopically showing better resistance to crack expansion.
