Pemanfaatan Fly Ash dan Bottom Ash Sebagai Material Stabilisasi Tanah Terhadap Nilai Kuat Tekan Bebas (Studi Kasus Jl. Raya Kadomas, Kecamatan Pandeglang, Kabupaten Pandeglang, Banten)
Daftar Isi:
- In building a road, land is the most important part to support all traffic loads or construction loads placed on it. Therefore, in planning a construction, an investigation must be carried out on the characteristics and strength of the soil, especially the properties of the soil that affect the supporting strength of the soil in withstanding the construction load on it. At the location of Jl. Raya Kadomas, Pandeglang District, Pandeglang Regency, Banten, the condition on the road was damaged quite severely and was often passed by land transportation modes so that the comfort and safety of vehicle access users were disturbed. The purpose of this study is to determine soil characteristics based on the classification and physical properties of the original soil of the Unified Soil Classification System method and find out soil characteristics and the effect of adding variations in fly ash percentages of 0% and 20% as well as variations in the presentation of Bottom Ash 0%, 10%, 20%, and 30% as an added material for soil stabilization to the value of unconfined compression test with variations in the deepening time of 0, 7, 14, and 28 days. The results of this study obtained soil classification including the OH type according to the Unified Soil Classification System (USCS) classification system, namely organic clay soils with high plasticity of 21.08%. The qu value is found in mixed soils Bottom Ash 10% and Fly Ash 20% with a deepening time of 28 days which is 2,994 kg / cm2. Soils with the addition of 0% and 20% Fly Ash and Bottom Ash at variations of 0%, 10%, 20%, and 30% showed a decrease in the value of the soil plasticity index from 21.083% to 7.511%.
