Abstract:In order to inspect the damage and manage the intelligent system to prolong the life of asphalt concrete pavement, a new electric conductive function concrete material functionalized with polyaniline/polypropylene (PANI/PP) compound conductive fiber as the electric conduction phase was investigated. The press susceptivity experiment of the asphalt concrete indicates that the constant electric conductivity of concrete increases with the press increasing and the acceleration declines with time and the electric conductivity finally reaches that of compound fiber. The mechanism of the electric conduction of the asphalt concrete is explained by using electric channels and tunnel effect in which a net factor, n is introduced, which indicates the capability of conductive net formation in the concrete. Based on the percolation conductive theory, a conductivity equation of conductive fiber bituminous mixture is established and the scope of corresponding parameter is determined.
