Temperature-adjusting asphalt road structure
The invention relates to the field of road engineering, in particular to a temperature-adjusting asphalt road structure comprising an asphalt surface layer and a phase change material layer arranged on the surface of the asphalt surface layer, and the phase change material layer comprises cured oil-soluble epoxy resin and phase change temperature adjusting microcapsules distributed in the cured oil-soluble epoxy resin. According to the temperature-adjusting asphalt road structure provided by the invention, the temperature of the whole road structure can be adjusted through the phase-change temperature-adjusting microcapsules in the phase-change material layer; the temperature-adjusting asphalt road structure has two functions of melting snow and inhibiting ice at the same time, so that thecooling rate of a pavement can be remarkably reduced and road diseases (such as snow accumulation, icing and the like on the pavement in winter) in cold weather can be effectively reduced; and the temperature of the pavement containing the phase-change material layer can be higher than that of the pavement without the coating by over 3 DEG C in a low-temperature environment.
本发明涉及道路工程领域，特别是涉及一种调温沥青道路结构。本发明提供一种调温沥青道路结构，包括沥青面层、和位于沥青面层表面的相变材料层，所述相变材料层包括固化的油溶性环氧树脂、以及分布于固化的油溶性环氧树脂中的相变调温微胶囊。本发明所提供的调温沥青道路结构可以通过相变材料层中的相变调温微胶囊对整体道路结构进行温度调节，同时具有融雪和抑冰两种功能，从而能显著减缓道面的降温速率，有效减轻寒冷气候下的道路病害(例如，冬季路面积雪、结冰等问题)，在低温环境下，含有相变材料层的路面可以较不含涂层的路面温度高3摄氏度以上。
