Environment-friendly cement stabilized macadam mixing process
The invention discloses an environment-friendly cement stabilized macadam mixing process, which is used for manufacturing environment-friendly cement stabilized macadam, and comprises the following steps: crushing RAP, screening, and grading into regenerated aggregate; crushing the recycled aggregate, screening, and grading to obtain recycled aggregate; prepared cement paste is prepared; mixing the graded recycled aggregates according to preset time to prepare mixed recycled coarse aggregates; the graded recycled aggregate with the particle diameter of 0-4.75 mm is selected and mixed with cement paste according to preset time to prepare cement mortar; mixing the mixed regenerated coarse aggregate with cement mortar to prepare environment-friendly cement stabilized macadam according to preset time; the total mixing time is not less than 15 seconds. The problem of recycling of solid waste road materials is solved, and by controlling the mixing time and optimizing the technological process, the mixing uniformity of the mixture is favorably improved, and the strength and crack resistance of a road subbase layer are favorably improved.
本发明公开了一种环保型水泥稳定碎石拌合工艺，用于制造环保型水泥稳定碎石，包括如下步骤：将RAP破碎后筛分，分级成再生集料；将再生骨料破碎后筛分，分级成再生集料；准备制备好的水泥浆；选用分级后的再生集料按照预设时间拌合制成混合再生粗集料；选用分级后的颗粒直径0‑4.75mm再生集料与水泥浆按照预设时间拌合制备成水泥砂浆；将混合再生粗集料与水泥砂浆拌合按照预设时间制成环保型水泥稳定碎石；总的拌合时间不少于15s。本发明解决了固体废旧路材的再生利用问题，通过拌合时间的控制及工艺流程的优化，有助于提升混合料拌合的均匀性，有助于提高道路底基层强度和抗裂性。
