Preparation method of emulsified asphalt cold recycled mixture
The invention provides a preparation method of an emulsified asphalt cold-recycled mixture, which comprises the following steps: adding water into a fine RAP material, vibrating and mixing to obtain a first premixed material; mixing a coarse RAP material with aggregate, adding water, and stirring to obtain a second premixed material; and adding the second premixed material into the first premixed material, then adding emulsified asphalt, vibrating and uniformly mixing, then adding mineral powder and cement, and continuously stirring to obtain an emulsified asphalt cold-recycled mixture, wherein the particle size of the coarse RAP material is 15-25 mm, and the particle size of the fine RAP material is 0.01-15 mm. According to the method disclosed by the invention, the aggregate is more uniformly and fully wrapped by the emulsified asphalt, so that the generation of gray materials is basically eliminated, the adhesion between the emulsified asphalt and the aggregate is enhanced, and the microscopic uniformity of the mixture is improved, thereby effectively improving the high and low temperature performance and freeze-thaw damage resistance of the cold recycled asphalt mixture.
本发明提供了一种乳化沥青冷再生混合料的制备方法，包括以下步骤：向细RAP材料中加入水，振动拌和后得到第一预拌和料；将粗RAP材料与集料混合后再加入水，拌和后得到第二预拌和料；将第二预拌和料加入至第一预拌和料中然后加入乳化沥青，振动拌和均匀后再加入矿粉与水泥继续搅拌即得乳化沥青冷再生混合料；其中，粗RAP材料粒径为15～25mm，细RAP材料粒径为0.01～15mm。本发明的方法集料被乳化沥青包裹得更均匀充分，基本上消除了花白料的产生，增强了乳化沥青与集料之间的粘附性，提高了混合料的微观均匀性，从而使冷再生沥青混合料的高低温性能以及抗冻融损伤能力得到了有效提升。
