Ice/snow on pavements is a constant threat to traffic safety and needs to be removed efficiently. Graphene as novel carbon nanomaterial have excellent microwave-absorbing and mechanical properties, making it the most favorable candidate for heating-generation composites. But there is a problem of uneven dispersion when introducing them through traditional processes. This research aims to fabricate graphene-coated functional aggregate (FLG@FA) to boost pavement deicing via a new coating method and high-temperature curing process. Microwace deicing and Low-temperature semi-circular bending (SCB) test at a low load-line displacement (LLD) rate were conducted to evaluate the ice-melting and low-temperature performance. Results show that deicing velocity of FLG@FA could be enhanced to 29.6 g/min (~64%↑). It also demonstrated an enhanced level of low-temperature cracking resistance (~31.4%↑) evaluated by calculating modified fracture work (Wf).
