Thermal and Mechanical Properties of Glass Cullet Mixed with Asphalt as Low-Exothermic Pavement Material

The asphalt pavement contributes to the heat island phenomenon of the city. Thus in order to decrease the temperature of asphalt pavement and to utilize glass cullet as a recycling material as an aggregate, some tests were carried out. In this study the specimen in which the cullet was entrapped in cold-laid paving materials and non-mixing specimen are made respectively, and the surface temperature of each specimen is measured by the thermal video camera. A set of tests have been conducted and results indicated the clear effect of glass cullet in reducing the radiation temperature of asphalt pavement
