The anti-icing asphalt pavement is a pavement method developed to prevent accidents caused by slipping during black ice and snowfall on the road in winter. In this study, test beds were conducted using Grikol, a representative anti-icing agent, for asphalt pavement. The durability and anti-icing effect of the anti-icing asphalt pavement were analyzed through the long-term performance evaluation of the test bed section. As a result of the analysis, it was confirmed that the anti-icing asphalt pavement using Grikol did not reduce the durability performance in the deformation strength (S_D) and indirect tensile strength (ITS) tests. In addition, even after 48 months of construction, it was found to have an effect of suppressing freezing up to a temperature of –2.9°C. Also, it was confirmed that there was a anti-icing effect during snowfall in the test bed section.
