Experimental Study on Engineering Properties of Soft Soil Stabilized by Overboulder Asbuton
Buton Island in Southeast Sulawesi, Indonesia, has a large amount of over 660 million metric tons of asphalt deposit in many forms. One of the types is overboulder which about 30% of the total deposit of asbuton. Overboulder occurred naturally when limestone reacts with bitumen in the topsoil layer of asbuton itself, making it a waste material which could be used as stabilizer material, due to its lime content with low bitumen content at about below 2%. The objective of this research was to analyze the effect of overboulder addition to soft soil as a pozzolanic agent and certain curing time to its unconfined compressive strength and CBR value. The soft soil was compacted according to ASTM D-698 standard method, as well as soft soil with overboulder addition. The UCT and CBR specimen was remolded based on its optimum moisture content and maximum dry density obtained from the compaction test. The unconfined compressive test was conducted according to ASTM D-2166 methods, and CBR test was conducted according to ASTM D-1883 methods. All specimen was treated with 0, 3, 7, 14, and 21 days of curing time in order to maximize its pozzolanic reaction between soil and overboulder asbuton. The overall result of the test shows that overboulder asbuton addition to soft soil increases its mechanical/engineering properties. Overboulder asbuton has potential as a local alternative to cement and/or lime in soil–cement and/or soil–lime stabilization due to its pozzolanic properties.
