Reflective asphalt mixture and preparation method thereof
The invention belongs to the technical field of road building materials, and particularly relates to a reflective asphalt mixture and a preparation method thereof. The invention provides a reflective asphalt mixture. The reflective asphalt mixture comprises the following components in parts by weight: 4-5 parts of asphalt, 0.5-1 part of an anti-stripping agent, 8-9 parts of glass beads, 80-85 parts of aggregate, 3-4 parts of mineral powder and 1-2 parts of pitchstone powder. The invention also provides a preparation method of the reflective asphalt mixture, which sequentially comprises the following steps: S1, cleaning and drying the aggregate and the glass beads, heating to 140-180 DEG C, and mixing by a stirring mixer to obtain a front material; s2, adding asphalt and an anti-stripping agent into the front material, and mixing through a stirring mixer to obtain an intermediate material; s3, mineral powder and pitchstone powder are added into the intermediate material and mixed through a stirring and mixing machine, the reflective asphalt mixture is obtained, the reflective property of the pavement is increased along with the increase of the content of the glass beads, and by adding a proper amount of pitchstone powder, the strength of the asphalt mixture can be enhanced, and ruts and cracks are prevented.
本发明属于道路建筑材料技术领域，尤其涉及一种反光沥青混合料及其制备方法。本发明提供一种反光沥青混合料，包括按重量计的以下各组分：沥青4‑5份、抗剥落剂0.5‑1份、玻璃珠8‑9份、集料80‑85份、矿粉3‑4份、松脂岩粉1‑2份。本发明还提供一种反光沥青混合料的制备方法，依次包括以下步骤：S1、将集料、玻璃珠清洗、烘干后加热至140℃‑180℃后，通过搅拌混合机进行混合，得到前料；S2、在所述前料中加入沥青和抗剥落剂，通过搅拌混合机混合，得到中间料；S3、在所述中间料中加入矿粉和松脂岩粉，通过搅拌混合机混合，得到反光沥青混合料，随着玻璃珠含量的增加，路面的反光性也随之增加，通过加入适量的松脂岩粉，能增强沥青混合料的强度，防止出现车辙和开裂。
