The pavement constructions on soft and expansive soils are not durable and unable to sustain heavy traffic loading. As a result, pavement failures and settlement problems will occur very often even under light traffic loading due to cyclic and rolling effects. Geotechnical engineers have dwelled deeply into this matter, and adopt various methods to improve the engineering characteristics of sof...

The existence of specific expansive minerals in the clay soil related to the climatological conditions, seasonable variation of rainfall precipitation (wet and dry periods) and fluctuation of water table in Mediterranean countries, has resulted to induce unexpected shrinkage and swelling movements with all the unfavourable consequences. It was observed that light industrial structures and small...

Expansive soil is collected near the mirchi yard gutur district, where NH 5 expansion is taking place. This study revealed that the fiber reinforcement improves the CBR values in admixture stabilized soil. In the present work, an attempt is made to compare the quantity of the earth required for the sub grade with and without fly ash stabilization, for 1.5% of fiber and 15 % of fly ash the thick...

In the context of sustainable development which is a balancing act between the fulfilment of human needs and the protection of the natural environment, the use of natural fibers such as coir in geotechnical applications is desirable. Reinforcing the soil with coir fibers/coir geotextiles is a cost effective solution to the ground/soil improvement problems. The effects of fiber parameters on the...

The rapid growth in population and industrialization cause generation of large quantities of effluents. The bulk effluents generated from industrial activities are discharged either treated or untreated over the soil leading to changes in soil properties causing improvement or degradation of engineering behaviour of soil. If there is an improvement in engineering behaviour of soil, there is a v...

Abstract This study was to evaluate the engineering properties of cement stabilized expansive clay soils. considered an experimental program determine Atterberg limits, free swell index, compaction characteristics, California Bearing Ratio (CBR), and mixtures. The collected soils were using 10, 12, 14, 16 % by weight. laboratory results showed that have low shear strength high swelling potentia...

In this investigation, silica fume (SF) was used as an additive material to study its influence on the characteristics of expansive soil. The soil in research prepared a lab by mingling bentonite (50 percent dry weight) with natural According (USCS), classified (CH) liquid limit 67.5 and plastic 29.3%. Expansive mixed different percentages (SF), (8, 9, 10, 11, 12, 13%), experiments were conduct...
