| Research Abstract |
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.
