Phase change heat storage type asphalt mixture and preparation method thereof
The invention belongs to the technical field of preparation of asphalt mixtures, and particularly relates to a phase change heat storage type asphalt mixture and a preparation method thereof.The phase change heat storage type asphalt mixture is prepared from, by mass, 86.42-88.98 parts of aggregate, 4.22-4.35 parts of asphalt, 5.51-5.68 parts of filler and 0.99-3.85 parts of phase change heat storage particles; the phase change heat storage particles comprise a carrier material, a packaging material and a phase change heat storage material, the carrier material is expanded graphite, the packaging material is silica sol, and the phase change heat storage material is polyethylene glycol; the mass ratio of the carrier material to the packaging material to the phase change heat storage material is (2.4-3.0): 10: (24-24.6). The phase change heat storage type asphalt mixture has the beneficial effects that the cooling amplitude of the phase change heat storage type asphalt mixture is 1.5-6 DEG C; the phase change heat storage particles absorb and store heat in a phase change mode, and the heating rate of the pavement is reduced; the particle size of the phase change heat storage particles is smaller than 1.18 mm, and the phase change heat storage particles can be used for preparing an asphalt mixture.
本发明属于沥青混合料的制备技术领域，具体涉及一种相变储热型沥青混合料及其制备方法，按质量份数计，包括86.42～88.98份集料、4.22份～4.35份沥青、5.51份～5.68份填料和0.99份～3.85份相变储热颗粒；相变储热颗粒包括载体材料、封装材料和相变储热材料，载体材料为膨胀石墨，封装材料为硅溶胶，相变储热材料为聚乙二醇；载体材料、封装材料和相变储热材料的质量比例为2.4～3.0：10：24～24.6。本发明的有益效果：该相变储热型沥青混合料的降温幅度为1.5～6℃；相变储热颗粒自身相变吸收并储存热量，降低路面的升温速率；相变储热颗粒的粒径小于1.18mm，能用于制备沥青混合料。
