A New Transient Method to Measure Thermal Conductivity of Asphalt

Abstract

The modern market of testing equipment provides new alternatives in choosing the most suitable and effective method to measure thermal properties of any material. C-Therm Technologies offers a new solution with respect to measuring thermal properties of asphalt concrete materials. The C-Therm TCi Thermal Property Analyzer allows determining accurate values for thermal conductivity and thermal effusivity of asphalt concrete without extensive sample preparation or damage to the sample. This technique has clear advantages over other existing techniques, one of which is the capability to test asphalt materials in situ. Laboratory testing was done for two types of asphalt concrete samples: lightweight and normal weight. A comparison analysis with other existing test methods demonstrated the applicability of C-Therm TCi System to asphalt concretes
