Cement stabilized macadam mixture recycled in cold region and preparation method of cement stabilized macadam mixture
The invention discloses a cement stabilized macadam mixture recycled in cold regions and a preparation method thereof, and the cement stabilized macadam mixture comprises the following components in parts by weight: 24-49 parts of natural coarse aggregate, 24-49 parts of regenerated brick-mixed coarse aggregate, 24-30 parts of regenerated brick-mixed fine aggregate, 3.5-4.5 parts of cement, 0.5-1.5 parts of fly ash, 0.2 part of modified rubber powder and 9.1-11.6 parts of water, the cement stabilized macadam mixture capable of being recycled in the cold region, provided by the invention, is high in strength and good in anti-freezing property, and second-generation recycled coarse aggregate obtained by crushing after five times of freezing and thawing cycles meets the physical property requirements of second-class recycled coarse aggregate; the second-generation cement stabilized macadam mixture prepared from the concrete has good frost resistance, can be recycled in cold regions, solves the problem of reutilization of regenerated brick-mixed aggregate and waste rubber powder, and has considerable economic benefits and environmental protection values.
本发明公开了寒冷地区循环使用的水泥稳定碎石混合料及其制备方法，包括以下重量份的各组分：天然粗骨料24‑49份、再生砖混粗骨料24‑49份、再生砖混细骨料24‑30份、水泥3.5‑4.5份、粉煤灰0.5‑1.5份、改性橡胶粉0.2份和水9.1‑11.6份，本发明提供的可在寒冷地区循环使用的水泥稳定碎石混合料强度高、抗冻性能好，经过5次冻融循环后破碎得到的第二代再生粗骨料满足第Ⅱ类再生粗骨料物理性能要求，使用其制备而成的第二代水泥稳定碎石混合料同样具备良好的抗冻性能，可以在寒冷地区循环使用，解决了再生砖混骨料和废弃橡胶粉的再利用问题，同时具备可观的经济效益与环保价值。
