Self-heat-absorption anti-icing pavement and preparation method thereof
The invention discloses a self-heat-absorption anti-icing pavement and a preparation method thereof, and belongs to the technical field of road traffic. The preparation method comprises the followingsteps: pretreating a hydrated salt phase change material, packaging to obtain a heat storage aggregate, mixing the heat storage aggregate with an aggregate, a cementing material and an additive to prepare a pavement material, and maintaining the pavement material to obtain the self-heat-absorption anti-icing pavement. The hydrated salt phase change material is mixed with a concrete or asphalt pavement by utilizing the phase change heat storage capacity of the hydrated salt phase change material, absorbs heat in the daytime with high temperature, releases heat at night with low temperature, keeps the pavement temperature, prevents the pavement from icing, and is suitable for pavement freezing prevention in areas with strong sunlight in the daytime and large day-night temperature difference.
本发明公开了一种自吸热防结冰路面及其制备方法，属于道路交通技术领域。所述制备方法为将水合盐相变材料进行预处理，经过封装作为储热骨料，然后与集料、胶凝材料、外加剂混合，制备成路面材料，然后经过养护得到自吸热防结冰路面。本发明利用水合盐相变材料的相变储热能力，与混凝土或沥青路面混合，在温度高的白天吸收热量，于温度低的晚上释放热量，保持路面温度，防止路面结冰，适用于白天日照强、昼夜温差大的地区的路面防冻。
