| Abstract | This study deals with the analysis of problem soils such as dispersive, erodible, swelling and collapsible soils found along the Naypyidaw - Mandalay expressway of Myanmar. To better understand the phenomenon of those problem soils, identification tests of dispersive soils using crumb test, double hydrometer test, pinhole test and soil chemical test were performed on each soil units taken from six - studied sites. Since each di spersive test shows different dispersivity of soil, the results from all tests and analyses are generally combined into rating systems and classify the soil by weighed factor of each test to determine whether the soil is dispersive or not. To know the eros ive soils behavior, pinhole test was accomplished on collected soil samples with the different dry unit weights. Conventional oedometer cells under one - dimensional condition were used in swelling and collapse potential tests. Swelling tests are performed on the soil samples with the natural water content and initial dry unit weight subjected to seating load of about 2 kPa with introduction water and loaded incrementally on these samples to know the swelling potential. Double oedometer tests on the soil sa mples with the different initial dry unit weight subjected to various initial overburden stresses (or seating loads) ranging from 3.5 to 100 kPa without introduction water and once the sample reached stable conditions, water was added and loaded incrementa lly on those samples to determine their collapse behavior. Physical properties of these soils such as Atterberg limits, grain size distribution and specific gravity were also performed and classify the soils by Unified Soil Classification System. Lastly , possible causes of problems happen on Naypyidaw - Mandalay Expressway are verified. |
