Highlight The difference of de-icing effect of different types of eco-friendly de-icing asphalt mixture(EDAM) is analyzed. The pavement performance of de-icing asphalt mixtures in the simulated pavement service conditions is studied. The influence of the adhesiveness on the road performance and de-icing effect is discussed.
Abstract To address the icing problem on the road, this paper, based on the salt accumulation and de-icing technology, used binary acetate as the de-icing material to prepare an eco-friendly de-icing filler(EDF), and EDF replaced the mineral fillers into four types of asphalt mixtures of matrix, SBS, high viscosity and rubber to prepare four different eco-friendly de-icing asphalt mixtures (EDAM). The compatibility and adhesiveness of four types of asphalt with the EDF were studied by scanning electron microscope test and pull-out test. By setting the freeze–thaw cycle conditions, the performance changes of water stability and low-temperature crack resistance of the four types of EDAM were studied. The pavement-ice interface adhesion reduction test and de-icing salt precipitation test were used to analyze the differences in the de-icing effect of four types of EDAM. The test results show that the adhesiveness between four types of asphalt mastic and EDF are different, which has an important impact on the road performance; In the freeze–thaw cycle environment, the addition of EDF damages the water stability and low temperature flexibility of the asphalt mixture, but enhances the anti-rutting performance after washout. In the de-icing effect, the four types of EDMA show various performances. This paper shows that the road performance and de-icing performance of EDMA with high viscosity are the best, which provides a new method for deicing asphalt pavement.
