Abstract：

This　preliminary　laboratory　research　aims　to　explore　the　impact　of　nanoclay　and　carbon　microfiber　in　combating　the　deterioration　of　asphalt　concrete　by　non-chloride　deicers.　Modified　boiling　water　test,　electrochemical　impedance　spectroscopy　(EIS)　and　contact　angle　test　were　employed　to　investigate　the　effects　of　nanoclay　and　carbon　microfiber　on　asphalt　concrete　in　the　presence　of　four　non-chloride　deicers,　namely,　dipotassium　succinate,　potassium　formate,　potassium　propionate　and　potassium　acetate.　The　results　indicated　that　the　incorporation　of　small　amount　of　nanoclay　in　asphalt　concrete　produced　a　notably　improved　stripping　resistance　and　reduced　moisture　susceptibility,　while　the　addition　of　carbon　microfiber　increased　moisture　susceptibility.　The　deterioration　effect　of　the　four　non-chloride　deicers　on　asphalt　mastic　was　discussed　based　on　their　molecule＇s　hydrophilic-lipophilic　properties.　©　2017　Elsevier　Ltd
