Migration characteristic and model of chloride ions for NaCl-based salt storage asphalt mixtures

Ouming Xu et al.

Summary: This study investigated the migration characteristics and model of chloride ions in salt storage asphalt mixtures through natural leaching test. The results showed that residual chloride ions content and attenuation rate decreased with increasing leaching time, while high leaching temperature and content of salt storage fillers accelerated the motion of chloride ions. The established migration model could predict the residual chloride ions content in the asphalt mixtures under certain work conditions.

Laboratory evaluation of a sustainable additive for anti-icing asphalt

Yan Zhang et al.

Summary: The novel sustainable anti-icing asphalt pavement additives, developed through surface treatment, showed significant improvements in anti-icing performance, mechanical properties, and durability, with promising results in fog-freezing friction tests. Incorporating these additives resulted in enhanced anti-icing capability, improved pavement friction coefficient, and better resistance against rutting, fatigue cracking, and thermal cracking in asphalt mixtures, attributed to asphalt-epoxy chemical reactions.
