Soil hydraulic properties play a crucial role in simulating water flow and contaminant transport. Soil hydraulic properties are commonly measured using homogenized soil samples. However, soil structure has a significant effect on the soil ability to retain and to conduct water, particularly in aggregated soils. In order to determine the effect of s...

Several materials such as tuff and Tripoli which is naturally occurring and industrial by-products wastes as high calcium ash and slag were investigated as cement substitutes in this paper. Compressive strength of various standard mortar samples have been tested at 7 and 28 days. The obtained results show that these materials have improved the prop...

Soil treatment is commonly resorted in order to improve the strength, stiffness properties of road foundations, and reduce the swelling potential of expansive soils. In Jordan, considerable amount of construction activity is carried out at relatively shallow depths where soil is likely to be unsaturated and subjected to low stresses level. Road dam...

This paper aims to investigate the effect of soil contamination by oil on the geotechnical properties of the soil and evaluation of the feasibility of using electrochemical method for the treatment of the contaminated soils. The properties of contaminated soil samples by different proportions of lubricating oil were determined and compared with the...

The soil structure is very important in understanding the behaviour of soil particularly in unsaturated case. The behaviour of unsaturated soil is highly influenced by microscopic structure of soil. Many electronic and optical microscopic observation have been made in this study. This paper shows the water is never been uniformly distributed with t...

Oil shale exploitation combined with producing huge amount of ash. In this paper oil shale ash is used as admixture of cement. The effect of partial replacement of cement by oil shale ash on the compressive strength, setting time and soundness of cement paste has been studied. Replacement of mortar cement by oil shale ash with ratios of 10, 20, and...

Many tests have been carried out to investigate the effects of mixing Karak clay soil with treated and raw domestic wastewater on the behavior of unsaturated soil. The specimens have been prepared by mixing the soil with three kinds of water; distilled water, treated wastewater and raw domestic wastewater. A specific experimental programme has been...

In Jordan, considerable amount of construction activity is carried out at relatively shallow depths where soil is likely to be unsaturated and subjected to low stresses level. One particular example is the pavement. The occurrence of damage to road founded on unsaturated subgrade in Karak, Jordan is due to the collapse of the soil structure upon we...

Many tests have been carried out on Karak clay to explore the unsaturated shear strength and volume change characteristics. The specimens have been prepared with and without treated contaminated water. A specific experimental programme has been planned and completed on a range of degree of saturation. The shear strength test and swelling test resul...
