This study conducted performance evaluation of deicing asphalt mixtures with anti-icing additives and proposed a solution to reduce the negative influences of anti-icing additives on the engineering properties of asphalt mixtures. Engineering property tests, including high-temperature wheel tracking test, low temperature three-point bending beam test, Marshall test and splitting test were conducted to evaluate the engineering properties of deicing asphalt mixtures. It is found that the anti-icing additives have negative effects on the rutting stability, thermal cracking resistance and moisture susceptibility of asphalt mixture. The addition of polyester fibers can compromise the negative effects by anti-icing additives to get fiber-reinforced deicing asphalt mixtures with satisfied engineering property. The anti-icing capacity of deicing asphalt mixture was also evaluated based on testing road observation and laboratory tests such as ice melting test, ice-mixture bond observation test, ice layer rupture test and ice layer pull-out test. It is proved that the anti-icing additives can be released from asphalt mixtures to help the melting of snow/ice and weaken the bond between ice and mixture effectively, which is helpful to keep the skid resistance of asphalt pavement. The findings indicate the fiber-reinforced deicing asphalt mixtures provide a promising way to build self-ice-melting asphalt pavement with well performance. (C) 2016 Elsevier Ltd.
