Abstract

High rainfall is observed in a tropical climatic country like Thailand that results in higher chances of natural calamities like flood. High plastic clay known as Bangkok clay is present in Thailand. The clay is famous for displaying variability in its geotechnical properties under dry and wet conditions. Therefore, such clay must be treated with some other materials for the stability of roads along with vehicles running through them. Bottom ash that is one of the waste materials produced from coal combustion has been used for this study along with lime. Tests like unconfined compressive strength test, durability test has been conducted by determining the strength under dry and wet condition. Two methods of soaking have been adopted when performing wetting-drying namely complete and capillary soaking. The results showed improvement in strength as well as durability after replacement with bottom ash and lime. The strength of the soil specimen after treatment with bottom ash and lime has improved 2 -fold with 50% amount of bottom ash and 12% lime. The same ratio of materials: 50% bottom ash and lime with the clay showed the optimum amount in terms of durability.
