<![CDATA[In the implementation of building construction, ground work was the first step that need attention to support a structure. Currently, an access to a tourism object on top of Swajah mountain Kayubatu Base-G, Tanjung Ria, North Jayapura District of Jayapura has been construct. In terms of constructing around the street, should be noted the soil conditions. This study wants to know the physical properties and mechanical properties of the area. The research result would be based on physical properties soil test according to USCD classification system, AASHTO classification system, and triaxle mechanical test. According to USCD, that Soil I and Soil III are classified as fine grained soil MH-OH group, which is inorganic silt soil or fine sand soil, elastic silt soil and organic clay soil with medium to high plasticity. While, Soil II is classified as fine grained soil CH group, thus inorganic clay soil with high plasticity. Then, according to AASHTO showed that the three soil are classified as A-7-5 group in clay soil. The triaxle unconsolidated-undrained soil test concluded the mechanical properties of cohesive value (c) and shear angle (ϕ) respectively are as follow: Soil I 0,015 kg/cm2 and 12,37o. Soil II 0,012 kg/cm2 and 9,31o. Soil III 0,014 kg/cm2 and 11,21o.]]>
