The Durability Evaluation Of Gabage Incineration Slag As Road Base Material

With the rapid development of today’s society, more and more garbage there are. However the waste disposal sites are limited. So the minimization of the garbage becomes what the people focus on today. The municipal solid waste incineration slag(refers as MSWI),one of the main product after the garbage is deal with, has one ingredient which can strengthen the soil cement or improve the muck’ s stress or stability. Many studies have discussed the applicability, deformation properties, the impact on the surrounding after the MSWI is applied to the road base before. But the studies on durability about the material are less. In view of this, the following aspects been done in this paper.First, from the physics experiment and mechanical tests, we obtained the physical properties and mechanical properties of the mixed material incorporated with MSWI. Then we analyzed the influence of the MSWI on the physical properties and mechanical properties.Then, we done the dynamic triaxial test based on the research purposes. It includes dynamic deformation test and fatigue failure test. From the test, we studied the variation of the materials Resilient Modulus and damping ratio. We analyzed the variation of material incorporated with MSWI under the cyclic load form deformation properties\ energy dissipation and fatigue life. Then we compare the results with the soil cement and raw earth and analyzed material’s durability.Finally, combined damage mechanics, we established the material damage evolution equation on the basis of experiments. We also obtained the material’s constitutive model considering about the mixture’s damage. Using the test results, we evaluated the material’s durability.
