In view of the need to stabilise poor lateritic soil for road construction, this study investigated effects banana leaf ash (content retained on British Standard sieve No. 40) strength characteristics selected soils. This is with a ascertaining possibility using referenced (BLA) content soils, construction purpose. To achieve aim study, two samples were collected from identified borrow pits (on...

Recently, the bio-mediated soil improvement techniques have gained an increasing attention. In this method, bacteria was cultivated aerobically in laboratory and added to with reactant solutions such as urea calcium chloride. Most of existing studies are on sandy soils a few researches done silty soils. However, most nature compounds fine-grained coarse-grained soils, silt does not very good re...

The shrinkage limit is one of the Atterberg limits and a fundamental geotechnical parameter used to assess settlement other volume change parameters engineering soils containing clays. This paper describes index tests results on expansive soil treated with rice husk ash (RHA) 5%, 10% 15% quicklime activated (QARHA) obtained using laboratory testing procedure. representative was subjected classi...

This research endeavors to enhance soil classification methodologies in alignment with sustainability goals for mining and construction activities. The study focuses on the evaluation, classification, mapping of quaternary surface deposits Wadi As Suqah. To achieve this objective, an integration mineral analyses unified classes was employed. Various methods were utilized, including Geographic I...

The scarcity of road materials that can be used directly in the sub-base layer a without preparation has led to use non-conventional materials. This study describes feasibility using hydrated lime-treated cubitermes sp termite mound soils for construction, based on laboratory tests. Tests Atterberg limits, dry density, CBR, compressive strength, static modulus and measurement sinking material u...

Most chemical stabilization guidelines for subgrade/base use unconfined compressive strength (UCS) of treated soils as the primary acceptance criteria selecting optimum stabilizer in laboratory testing. Establishing optimal additive content to augment UCS involves a resource-intensive trial-and-error procedure. Also, samples collected from discrete locations trials may not be representative ove...

Abstract This study aims at the mineralogical and physicochemical characterization of clay formations Miocene age from Timgad Basin (Massif Aurès, NE Algeria), in order to evaluate their possible valorization, notably for potential use manufacturing bricks ceramic industry. For this purpose, four samples were taken a clay-dominated formation that outcrops 5 km east city. Each sample was collect...

Marine clay soils are problematic in the construction industry when they subjected to loads. When these loaded, lose their structure. This leads soil being unable withstand loads of any magnitude without exhibiting significant, permanent deformations. In order stabilize marine soil, new methods for improvement were built upon biogrouting by incorporating physical, biological and chemical treatm...

The study area is located in Upper Egypt as a part of the Sohag Governorate. In this study, engineering geological properties for soil deposits three new urban areas southwestern Governorate are discussed and evaluated based on field survey boring, geotechnical experiment petrographical examination. studied covered by Quaternary Pliocene composed mainly gravely sand, silty clay, clayey silt roc...
