The Study of Mixture Design for Foam Bitumen and the Polymeric and Oil Materials Function in Loose Soils Consolidation

摘要

Due to the enormous growth of new chemicals, especially polymer materials in construction projects, and the importance and effectiveness of these new materials in poor soil stabilization, recently has closed chemistry and polymer sciences to civil science. The use of materials such as bitumen in stabilization of flowing and loose soil and using of polymer resins reflects the effect of these substances is very high on construction projects. Considering the importance of oil and polymer materials in soil stabilization, in this study performance of polymer materials and their comparison have been investigated. Oil materials such as bitumen can be used to stabilize the soil, and polymer resins such as polyvinyl alcohol and polyvinyl acetate, and also pointed polypropylene synthetic fiber can be considered as polymer materials. Bitumen foam is one of the fixative materials that obtain by adding water to hot bitumen, and is applicable to a wide range of stone materials. In addition to, polymer resins increase the burden go loose soils. Polymer fibers due to high durability and easy application and no problem at saturation conditions are highly regarded by civil engineers.
