Preparation process of foam warm-mixing environment-friendly recycled asphalt mixture
The invention provides a preparation process of a foam warm-mixing environment-friendly recycled asphalt mixture, and belongs to the technical field of recycled asphalt mixture preparation, and the preparation process of the foam warm-mixing environment-friendly recycled asphalt mixture comprises the following steps: recycling recycled asphalt, and preparing aggregate and an asphalt modifier in proportion; the recycled asphalt is pretreated, and the uniformity of the recycled asphalt is guaranteed through screening, heating and drying in sequence; uniformly mixing the pre-treated recycled asphalt, the pre-treated aggregate and the pre-treated asphalt modifier according to the proportion; water and air are added into a foaming device, and stable foam is generated through high-speed stirring; mixing the foam with the mixture obtained in the previous step; the foamed asphalt mixture is placed in a stirring assembly to be treated, and the temperature and the mixing time are controlled; the process can solve the problems that an existing preparation process is high in temperature control energy consumption, complex in operation and difficult to accurately control the optimal mixing temperature and time of the mixture, and consequently the quality stability is difficult to control.
本发明提供了一种泡沫温拌环保型再生沥青混合料的制备工艺，属于再生沥青混合料制备技术领域，该泡沫温拌环保型再生沥青混合料的制备工艺为回收再生沥青，按照比例准备好骨料和沥青改性剂；对所述再生沥青进行预处理，依次经过筛分、加热、干燥的操作保证所述再生沥青的均匀性；按照比例将预处理后的所述再生沥青、所述骨料以及所述沥青改性剂混合均匀；将水和空气加入到发泡装置中，通过高速搅拌产生稳定的泡沫；将所述泡沫与上述混合物进行混合；将所述泡沫沥青混合料置于搅拌组件中处理，控制温度和混合时间；该工艺能够解决现有的制备工艺的温控能耗较高，操作复杂且难以准确控制混合料的最佳混合温度和时间，导致质量稳定性难以控制的问题。
