Abstract
The addition of anti-icing agents to asphalt pavements as a way to prevent snow and ice residues should consider not only the environmental aspects of anti-icing agents, but also the water stability, high temperature stability and low temperature crack resistance of asphalt mixes. In this work, environmentally and friendly slow-release anti-icing agent called MAS was produced by using silica microspheres coated with magnesium acetate, and the performance of the mixes after adding anti-icing agents was analyzed by the water stability, high temperature stability and low temperature crack resistance tests The experimental results show that when the MAS replaces 6% of 0–0.075 mm aggregate by equal volume, the strength and performance of the mixture meet the requirements and have the best slow-release effect.
