Prompt Description

ABSTRACT: Pavement icing presents significant safety and economic challenges, necessitating the development of effective and sustainable anti-icing technologies. This study aims to develop a novel dual-functional asphalt modifier that combines thermal regulation and hydrophobicity to actively inhibit ice formation. To achieve this, tetradecane was microencapsulated within a silica shell via interfacial polymerization to create phase change microcapsules (MPCMs). These MPCMs were then blended with polydimethylsiloxane (PDMS) to produce a composite modifier, which was incorporated into asphalt. The resulting MPCM/PDMS-modified asphalt was comprehensively characterized using thermal analysis, rheometry, fluorescence microscopy, and contact angle measurements. Key findings indicate that the composite modifier simul
