The main objective of this study is to evaluate the durability of anti-icing asphalt pavement using anti-icing agent (AIA) to mitigate numerous traffic slippery events caused by black ice or unobserved surface ice during winter season. The AIA was incorporated into the three asphalt mixes, a normal dense graded asphalt (DGA) mix, a stone mastic asphalt (SMA) mix and a porous asphalt (PA) mix, because the DGA is most widely appled to the national roads, SMA to expressways and PA to expressway for drainage purpose. To evaluate integrity of serviceability performance, the deformation strength (S_D), indirect tensile strength (ITS) and wheel tracking (WT) rut depth of the asphalt mixture with AIA were measured in the laboratory. As a result of the performance test, it was confirmed that the use of AIA did not degrade the durability of the asphalt mixture such as the volume characteristics, deformation strength, indirect tensile strength, and dynamic stability. In conclusions, it is therefore highly expected that the AIA-included asphalt mixture can be successfully applied to the field pavement to reduce traffic accidents by preventing formation of black ice and frozen snowy surface without pavement damages.
