摘要：
The changes of resistivity of conductive asphalt concrete at different temperatures were studied,and positive temperature coefficient(PTC)modelwas established to estimate the influence of temperature on the resistivity quantitatively,which eliminated the interference with conductivity evaluation brought by temperature variation.Finally,the analysis of temperature cycling test results proves that the changes of percolation network structure caused by temperature variation prompt the emergence of PTC of conductive asphalt concrete.
