TÓM TẮT
Temperature changes affect pavement performance such as strength reduction at elevated temperature or crack initiation and development at low thermal conditions. Thermal diffusivity of paving materials is one of parameters helps to determine exactly temperature distribution in pavement structures. Currently, the thermal diffusivity can be determined through thermal conductivity, mass density of material, and specific heat capacity. Nevertheless, the specific heat capacity is quite complicated to obtain for composite materials. Literature reported different experimental methods used for determining the thermal conductivity of building materials such as heat flow method (ASTM C 518), guarded-hot-plate approach (ASTM C 177), hot wire technique (ASTM C 1113), and transient plane heat source solution (ISO 22007-2:2015). However, these methods were found not suitable for pavements due to large granular …
