Abstract: Recycled tyre rubber was used to replace varying fractions of limestone as filler in asphalt in order to determine the effect that the added rubber would have on the thermal and physical properties of the asphalt. The properties of interest were the penetration, soft point, and ductility of the asphalt binder, as well as the moisture sensitivity, thermal conductivity, thermal diffusivity, and volumetric thermal capacity of the asphalt mixtures. It was determined that the addition of recycled tire rubber can improve the thermal insulation properties of asphalt binders and mixtures. It was also found that the addition of the rubber slightly reduced moisture resistance in the asphalt binders and mixtures.
