Preparation method of high-temperature-resistant and cracking-resistant asphalt mixture
The invention relates to the field of building materials, in particular to a preparation method of a high-temperature-resistant and cracking-resistant asphalt mixture. The asphalt mixture is prepared from asphalt, a hot aggregate of 6-13 mm, a hot aggregate of 4-6 mm, a hot aggregate of 0-4 mm, recycled mineral powder, a diluent and an additive. The asphalt mixture prepared by the invention has better high-temperature stability, and cannot generate diseases such as waves, pushing, ruts, upheaval and the like under the repeated action of driving loads in high-temperature seasons; the asphalt mixture prepared by the preparation method disclosed by the invention has relatively good crack resistance; the water stability is better, and the conditions of asphalt film stripping, grain falling, loosening, pit slots and the like are not easily generated; good fatigue resistance is achieved, and the structural strength of the pavement is stable.
本发明涉及建筑材料领域，具体关于一种耐高温抗裂化沥青混合料的制备方法；本发明采用沥青、6‑13mm热骨料、4‑6mm热骨料、0‑4mm热骨料、回收矿粉、稀释剂、添加剂，来制备沥青混合料；本发明制备的沥青混合料，具有较好的高温稳定性，在高温季节行车荷载反复作用下不会产生诸如波浪、推移、车辙、拥包等病害；本发明制备的沥青混合料，具有较好的抗裂性；具有较好的水稳定性，不容易产生沥青膜剥离、掉粒、松散、坑槽等情况；具有较好的耐疲劳性，路面结构强度稳定。
