Environment-friendly roadbed water stabilizing layer material prepared from iron tailing slag and preparation method of environment-friendly roadbed water stabilizing layer material
The invention belongs to the field of preparation of environment-friendly road surface water-stable layer materials, and particularly relates to an environment-friendly roadbed water-stable layer material prepared from iron tailing slag and a preparation method thereof.The environment-friendly roadbed water-stable layer material is prepared from, by mass, 3-5 parts of cement, 4-6 parts of calcium oxide, 3-10 parts of gravel below 50 mm, 5-10 parts of fly ash, 40-70 parts of fine-grained soil below 60 mm, and the particle size of waste iron tailing slag below 5 mm is controlled within 10-30 parts. And the use amount of the humidifying water is calculated according to the optimal water content obtained by a compaction test. The roadbed water-stable layer material disclosed by the invention can realize comprehensive treatment of various wastes at the same time, reduces the road repairing cost, also has water-resistant stability, and improves the strength of the water-stable layer material.
本发明属于环保型路面水稳层材料制备领域，尤其为利用铁尾矿渣制作的环保型路基水稳层材料及其制备方法，按照质量份数，水泥3‑5份，氧化钙4份‑6份，50mm以下碎石3‑10份，粉煤灰5‑10份，60mm以下细粒土40‑70份，5mm以下粒径废铁尾矿渣控制在10‑30份以内，0.02‑0.03份的复合稳定剂，由击实试验得出最佳含水率算出的增湿水用量。本发明的路基水稳层材料能同时实现多种废弃物的综合处理，降低修路成本，同时还具有抗水稳定性，提高水稳层材料强度。
