▎ 摘  要

NOVELTY - Self-induction conductive asphalt concrete comprises 84-90 pts. wt. aggregate, 2-4 pts. of mineral powder, 8-12 pt. of asphalt, 0.6-4 pt of powder conductive material, and 0.01-2 pt of surfactant. The powder conductivity material comprises chopped carbon fiber, graphite, carbon nanotubes, graphene, steel slag and steel fibers. USE - Self-induction conductive asphalt concrete is used as piezoresistive sensor for monitoring and commanding traffic, for development of intelligent traffic in future. ADVANTAGE - The self-induction conductive asphalt concrete has excellent performance, good conductivity, and convenient road traffic intelligent management and road internal structure damage monitoring, improves the conductivity of the asphalt concrete, and prevents the pavement crack disease. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of the self-induction conductive asphalt concrete. DESCRIPTION OF DRAWING(S) - The drawing shows a graph of resistivity and stress of the self-induction conductive asphalt concrete (Drawing includes non-English language text).
