This study aimed to investigate the geotechnical characteristics of the soil district Lasbela, Baluchistan, in the Porali river basin. Tests were carried out on the sample soil, including particle size analysis, Atterberg's limit tests, bulk and dry density, natural moisture content and modified proctor. The plasticity index and particle size study indicated that the soil was classified as A-1-a by AASHTO and as GP by the Unified Soil Classification System (USCS); Atterberg, A. (1911); D-2487 (1996). Maximum dry density and optimum moisture content values of soil samples evaluated TP-01, 03 and 05, 2.263 glcc, 2.256 glcc, 2.247 glcc and optimum moisture content is 6.2, 7.1 and 7.5% respectively. The soil was  proposed that the soil in road subgrade and other construction works would be excellent as a filling material and need alteration to enhance its sub-base and road base material properties.
