This study presents the swelling parameters for expansive soil from Monywa Township, Saging Region. In various civil engineering projects, soil is used as a construction material and it supports structural foundation. Expansive clay soils swell when they are wetted and shrink when they are dried out. Volume changes of expansive soils can cause damages to structure resting on them. Therefore, it is essential to identify the existence of expansive soil at proposed construction site. The present study deals with the properties of expansive soils from Institute of Economic IE , Industrial Zone IZ and Hospital of Traditional Medicine HTM which are situated in Monywa Township, Sagaing Region. In order to identify and classify the expansive potential of expansive soils, performed tests on soils under study are Atterberg limit tests, Grain size analysis, Specific gravity test, Standard compaction test, Modified free swell index test and Consolidation test. Then, the expansive potential is qualitatively classified by various classification methods. In this study, swell potential and swell pressure are considered as the swell parameters. Empirical correlations for swell parameters of expansive soil from Monywa Township are proposed by using multiple linear regression analysis for three dimensional models based on free swell test results.
