The invention discloses a preparation method of a novel environment-friendly roadbed material containing sludge. The preparation method comprises the following steps: preparing modified waste lime powder, sludge treatment substances, a soft soil curing agent and the like; and also comprises related preparation steps. Through simple roadbed material preparation steps, the method can be operated according to conventional conditions, has no special requirements on equipment, can meet the strength requirements of base layers and subbase layers of various roads, and has a wide application prospect in sludge solidification and stabilization; the material provided by the invention can effectively replace a traditional building material, the sludge is solidified to form a firm road base material, the problems of outward transportation, stacking and the like of the sludge are solved, and land occupation is reduced. According to the method, natural resources can be effectively saved, compared with a traditional method which causes waste of a large amount of stone, pond slag, cement, lime and other materials, efficient solidification and resource utilization are conducted on the sludge, the natural resources are saved, and energy consumption is reduced.
本发明公开了一种含污泥的新型环保路基材料的制备方法，包括对改性废石灰粉、污泥处理物、软土固化剂等配方同时还包括相关的制备步骤。本发明通过较为简单的路基材料制备步骤，可以按照常规条件操作，对设备没有特殊要求，有满足各类道路的基层和底基层强度要求，本方法对于污泥固化稳定化有着较为广泛的应用前景；本发明提供的材料能有效替代传统的建筑材料，污泥经固化后形成坚固的道路基层材料，解决了污泥外运、堆放等难题，减少土地占用。本发明能有效节约自然资源，相对于传统方法造成大量石料、塘渣、水泥和石灰等材料的浪费，本发明对污泥进行高效固化及资源化利用，节约自然资源，减低能源消耗。
