Carbon Fiber Heating Wire for Pavement Deicing

CODEN: JTEVAB

Abstract

The use of electric heating technology in pavement deicing has received considerable attention because of its fast and environmentally friendly features. Carbon fiber heating wire (CFHW) buried in concrete slabs is a type of technology that belongs in this category. This study conducts indoor heating tests to analyze and determine the factors that influence the heating rate of CFHW, including depth of installation, layout interval, input current, ambient temperature, and overlying material. A finite element model is established and calibrated by simulating the indoor heating tests. The heating effect of concrete pavement in different environmental conditions is analyzed through finite element simulation. Results show that CFHW is effective for pavement deicing.
