Stiffness Characteristics of the Packed-Dredged Materials Stabilized with Waste Plasterboard Powder and Its Application to Subgrade

湖泊、港口底泥和固体废物中间处理厂破碎的废石膏板虽然是有益的土料，但其利用仍处于停滞状态。在本研究中，湖泥海砂废石膏板稳定剂混合物包裹在土工织物作为基层/路基材料在沥青路面的适用性进行了研究，通过实验室试验和数值运算。结果表明，土工织物与混合料的结合对加筋土的抗拉强度有一定的增强作用。

Though the sediments dredged from floors of lakes and ports and the waste plasterboards crushed at solid waste intermediate treatment plants are beneficial earth materials, the utilization is still stagnant. In the present study, an applicability of the lake mud-sea sand-waste plasterboard-stabilizer mixture wrapped in geotextile as a base course/subgrade material in the asphalt pavement was examined by laboratory tests and numerical operations. The results indicated that the combining of a geotextile with the mixture brought reinforcement of tensile resistance.
