Abstract

The mechanical performance of cold asphalt mixtures (CAM) can be improved by using cement additions, but it is unclear how this affects the dynamics of water evaporation during drying. This paper investigates CAM samples with different contents and types of cement (ordinary Portland, calcium aluminate and calcium sulfoaluminate), tested by dynamic evaporation, hydraulic conductivity and Marshall test. The results show that cement does not significantly shorten the drying process, while bitumen emulsion delays cement hydration. Finally, a new predictive model was obtained to estimate the contribution of cement hydration products to the total stability of CAM.
