Recycled asphalt mixture and preparation method thereof
The invention relates to the field of asphalt mixture preparation, and particularly discloses a recycled asphalt mixture and a preparation method thereof. The recycled asphalt mixture comprises the following components in parts by weight: 450-500 parts of aggregate, 60-75 parts of asphalt and 20-25 parts of a recycling agent, wherein the aggregate comprises natural aggregate and recycled aggregate, and the weight ratio of the natural aggregate to the recycled aggregate is (3-4):1. The preparation method comprises the following steps: milling an asphalt pavement of a target pavement, and crushing into particles with the average particle size of 5 mm; mixing recycled aggregate and a recycling agent, and stirring for 1 minute at an ambient temperature of 160 DEG C; and adding natural aggregate and the asphalt in proportion, and stirring for 1 minute; The method has the effect of improving the utilization efficiency of the waste asphalt mixture.
本申请涉及沥青混合料制备的领域，具体公开了一种再生沥青混合料及其制备方法。一种再生沥青混合料按重量份计包括以下组分：骨料450～500份、沥青60～75份、再生剂20～25份，其中骨料包括天然骨料和再生骨料，天然骨料与再生骨料的重量比3～4:1。其制备方法为：将目标路面的沥青路面进行铣刨，破碎成平均粒径为5mm的颗粒；将再生骨料以及再生剂混合，160℃环境温度搅拌1min；按比例接着加入天然骨料和沥青，搅拌1min。本申请具有提高废弃沥青混料的利用效率的效果。
