Application of heated pavement systems is a safer and faster alternative to currently predominant 46 methods of removing ice and snow from paved surfaces. Heated pavements not only can remove 47 ice/snow from pavement surfaces, but are also capable of preventing their 48 formation/accumulation in the first place. Electrically conductive concrete (ECON) provides an 49 effective and powerful means of producing self-heating pavements. The electrical conductivity 50 of ECON is dependent on numerous factors such as type and dosage of electrically conductive 51 materials (ECMs), mix proportions, aggregate type, ECM dispersion, and ionic environment of 52 concrete. Admixtures can be used for manipulating the internal environment of concrete and/or 53 improve the performance of ECMs. An optimized ECON mix design should account for all 54 influencing factors. The objective of this research was to investigate the influence of a variety of 55 factors on electrical and mechanical characteristics of ECON. To this end, a factorial 56 experimental plan was prepared with five factors, all varying in two levels. The test results were 57 analyzed through regression analysis to quantitatively evaluate the significance of the effects of 58 each factor. The results showed that the dosage and type of ECM, mix proportions of concrete, 59 and admixtures exert a significant effect on electrical properties of ECON while also affecting its 60 mechanical characteristics.
