Project Background:
Ice and snow are the main factors affecting road safety in winter. Conventional ice and snow removal methods consist of the use of deicing chemicals and salts, snowplowing or often both. Such methods can be costly and labor intensive, may have environmental impacts, and can damage concrete pavement. The incorporation of phase change materials (PCM) in concrete pavement has been suggested as an alternative method for melting and removing both ice and snow from concrete pavement surfaces or controlling thermal response of concrete pavements during hydration.
Aims & Goals:
1. To develop a novel petroleum based phase change composite material and apply them to asphalt mixture pavement, with the target of achieving the effect of snow self-melting and deicing on road surfaces;
2. Realize the goals of industrial production of petroleum-based phase change composite materials and engineering demonstration of phase change asphalt mixture pavement;
3. Clarify the influence of phase change energy storage composite materials on the road performance of phase change asphalt mixtures and the mechanism of their self melting and deicing performance.
