Abstract The liquefaction event that occurred in Petobo Village, Palu City, Central Sulawesi, was caused by the earthquake on September 28 th , 2018 with a magnitude of 7.4 and depth 10 km. This study aims to determine characteristics soil also whether area still has potential for based Test Swedish Weight Sounding (SWS) Cone Penetration (CPT) . test is carried out at location limit cessation l...

Olive oil is concentrated in the Mediterranean basin countries. Since the olive oil industries are incriminated for a high quantity of pollution, it has become imperative to solve this problem by developing optimized systems for the treatment of olive oil wastes. This study proposes a solution to the problem. Burned olive waste ash is evaluated for using it as clay stabilizer. In a laboratory, ...

Role of Soil Plasticity in Evaluating Clay Conditioning for EPB Tunnelling Soil clogging occurred at the early construction stage of Nanchang Metro Line 1, China, when an earth balance pressure (EPB) shield passed through the argillaceous siltstone with a total content of clay minerals of 40.5%. To avoid the reappearance of soil clogging at the later stage, a new scheme was proposed to determin...

The study evaluated the effect of four treatment compositions on plasticity tropical red soil (Lateritic soil) admixed with Bacillus coagulans (B. coagulans). Samples for Atterberg limits test were prepared using compositional variables. They include 25% B. suspension and 75% cementation reagent, (25%B /75%C); 50% reagent (50% B /50%C); (75%B /25% C) above three being in equivalent volumes corr...

Abstract Expansive subgrade soil needs to be re-engineered enhance the load-bearing capacity as it lacks sustain traffic and pavement load. Although various chemical modification techniques have proven effective for stabilization, they are expensive unsustainable. Coronus aggregate material is an uplifted coralline deposit abundantly available in Pacific. The current study focuses on strength b...

Atterberg limits are broadly used for engineering and geology purposes as well in agricultural environmental applications. Laboratory methods their determination are, however, laborious, destructive tool dependent. The aim of this study was to test the feasibility using visible near-infrared spectroscopy (vis–NIRS) a fast accurate alternative conventional measurements (LL PL) PI 229 geographica...
