Granular lateritic soil is commonly used for road construction in humid tropical and subtropical regions. However, the high plastic clay content poor particle distribution of some laterite materials make them unsuitable bases subbases. Lime treatment a widely method improving problematic soil, liquid ionic stabilizers are considered an environmentally friendly solution reinforcing such soils. u...

The paper presents the effect of using cashew nut shell liquid (CNSL), a low-priced agro by-product and renewable resource, to treat coir geotextiles. Large-scale direct shear tests were performed on sands reinforced with untreated treated geotextiles at different normal stresses (50 kPa, 100 150 kPa). Sands three particle sizes (coarse, medium, fine) used for study. strength parameters soil sa...

in this study, we offer a general view at the area of fuzzy modeling and fuzzymodels, identify the visible development phases and elaborate on a new and promisingdirections of system modeling by introducing a concept of granular models. granularmodels, especially granular fuzzy models constitute an important generalization of existingfuzzy models and, in contrast to the existing models, generat...

This contribution tackles the issue of incipient conditions for initiation erosion by a fluid flow at surface cohesive materials. To this end, typical assessment procedure consists subjecting soil sample to progressive hydrodynamic stresses induced submerged impinging jet whose injection velocity is gradually increased. paper presents results an extensive use protocol both in experiments and nu...

in this study, micromorphological properties of some samples collected from pedons polluted with petroleum refinery wastes and some adjacent unpolluted pedons were studied. after description of the studied pedons, disturbed and undisturbed samples were collected for physicochemical and micromorphological analyses. the results showed that the physicochemical properties (i.e. structure, bulk dens...
