Pavement Performance and Ice-Melting Characteristics of Asphalt Mixtures Incorporating Slow-Release Deicing Agent

Icy pavement is one of the primary causes affecting driving safety in winter, and deicing asphalt mixture could effectively resist icing. This study evaluated effect a slow-release agent on performance ice-melting characteristics mixture. The containing four different contents (0%, 30%, 50%, 70% using internal mixing method) by replacing mineral filler was designed. Pavement tests were used to investigate high-temperature stability, cracking resistance, water stability Qualitative quantitative designed compare predict durability with replacement amounts. experimental results show that low-temperature decrease increase inthe agent. content 50% will enhance short term. Deicing can significantly improve ice snow melting ability pavement, reduce interface adhesion between more than 55%. reach maximum release concentration within two hours under rain snow. recommended amount predicted 5–8 years.
