This paper presents a method to deice concrete pavement with carbon nanotube (CNT) so as to avoid the adverse effects of conventional deicing method such as salt on the structure, function and environment. To meet the research objective, laboratory tests were incorporated with finite element method. Laboratory tests conducted with CNT embedded inside the slab to investigate how far the heat transfers on the surface temperature of above 0oC when CNT generates the target temperature of 60oC in the freezer temperature of -10oC. Also, the cases of three different spacing of 15, 20 and 30 cm between CNTs were conducted to determine the maximum allowable spacing of CNT. Along with these experimental tests, heat transferring analysis conducted to validate the test results.
