A methodology for the determination of bearing capacity of granular soils with plate loading tests
Abstract: In granular soils, due to the inability to collect undisturbed samples of soil for geotechnical laboratory tests or the impracticality of carrying out dynamic penetration tests, highlights the necessity to find a useful approach in the engineering geological practice for the determination of bearing capacity. In these soils the determination of bearing capacity can be evaluated with several formula that necessary require the estimation of the friction angle: this leads …

Geotechnical study of a landslide reactivation in clay soils (central Piedmont, NW Italy).
Abstract: In March 2015, exceptional meteoric events occurred in southern Piedmont caused a remarkable rise of the rivers water level of the Tanaro Basin with flooding and many landslides. The engineering geological study reported here, concerns a triggering of a previous landslide occurred in 1982 in the hills, shaped in the marine sedimentary succession (Lugagnano Clay, lower Pliocene) of the southern Asti Reliefs, near San Martino Alfieri village. Detailed geological, morphological …

INVESTIGATING THE GEOTECHNICAL PROPERTIES OF A LATERITIC SOIL AS A SUB-GRADE MATERIAL FOR ROAD CONSTRUCTION –USING COCONUT HUSK ASH
Abstract: Waste management world-wide plays a major role in socio-economic development over the years. The increase in population over the years has contributed to the rate at which wastes are generated. One major waste generated in Ghana is coconut shell waste. Out of the world producing of coconut, Ghana is ranked 16th. The management of these agricultural waste has become a vital challenge to the development to the Ghanaian economy and …

VARIATION OF THERMAL CONDUCTIVITY WITH POROSITY
Abstract: Thermal conductivity in porous media as a function of the grain size and porosity has been studied establishing a relation between these two parameters. The study has been developed for a homogeneous porous medium with grain size in a very close range of particle diameter. The study has been extended from very small particles to large ones, to cover most of the real grain size. As a result of this …

Effect of Alccofine and Tyre buffings on Engineering Properties of Sand
Abstract: In the present paper, the effect of alccofine and tyre buffings addition on the compression and bearing ratio of sand are evaluated through laboratory study. On the basis of compaction test, a reference mix composed of sand + 12 % alccofine + 2 % tire buffing was selected for further study. The unconfined compression and bearing ratio test on the reference mix was then carried out by curing the sample …
