Cement stabilized macadam mixture of full-recycled brick-mixed aggregate and preparation method of cement stabilized macadam mixture
The invention discloses a cement stabilized macadam mixture of full-recycled brick-mixed aggregate and a preparation method thereof, and the cement stabilized macadam mixture comprises the following components in parts by weight: 100 parts of aggregate, 4.5-5.5 parts of cement, 13.4-15.6 parts of water and 0-0.3 part of modified rubber powder, the aggregate comprises the following components in percentage by weight: 11-17% of 1 # material with the particle size of 19-31.5 mm, 24-30% of 2 # material with the particle size of 9.5-19 mm, 21-27% of 3 # material with the particle size of 4.75-9.5 mm, and 9-15% of 4 # material with the particle size of 2.36-4.75 mm. According to the invention, the utilization rate of the regenerated brick-mixed aggregate is increased, a new way of waste rubber powder is developed, and the waste rubber powder is recycled. The mechanical property of the cement stabilized macadam base material is influenced to a certain extent by using the regenerated brick-mixed aggregate and the rubber powder, but each index performance of the material can meet the requirements of related standards, and the shrinkage deformation of the cement stabilized macadam mixture is effectively reduced by using the rubber powder. The anti-cracking performance of the cement stabilized macadam base is favorably improved. And the 100% recycled brick-mixed aggregate is adopted, so that the engineering cost is greatly reduced, and environmental protection is facilitated.
本发明公开了一种全再生砖混骨料的水泥稳定碎石混合料及其制备方法，包括如下重量份的各组分：集料100份、水泥4.5‑5.5份和水13.4‑15.6份，改性橡胶粉0‑0.3份，集料的组成比例按重量百分数计包括：粒径为19‑31.5mm的1#料11‑17％、粒径为9.5‑19mm的2#料24‑30％、粒径4.75‑9.5mm的3#料21‑27％、粒径为2.36‑4.75mm的4#料9‑15％、本发明提高了再生砖混骨料的利用率，开拓废弃橡胶粉的新途径，再生砖混骨料和橡胶粉的使用一定程度上影响了水泥稳定碎石基层材料的力学性能，但该材料各项指标性能均能符合相关标准的要求，橡胶粉的使用有效地降低了水泥稳定碎石混合料的干缩变形，有利于提高水泥稳定碎石基层的抗裂性能。并且采用百分百再生砖混骨料大大降低工程成本，而且有利于环境的保护。
