Descriptif partiel
Processing of soil and paving materials requires water. In Israel, potable water is used for this purpose. An alternative to the use of expensive potable water could be the use of much less expensive treated effluent water (used extensively in agriculture) and saline water from local aquifers. However, no knowledge exists with respect to the possible impacts of nonpotable water on the geomechanical properties of soils. An indepth study of the engineering and environmental impacts of using non-potable water for the processing of earthworks and paving materials is therefore needed.
Goals of this research : The main goal of this study was to examine the effects of using non-potable water on geomechanical properties of soils and paving materials. The specific objectives of the study were : * a. Investigation of the impact of non-potable water on the engineering and physiochemical properties of soils and paving materials in comparison with potable water. * b. Quantification of long term effects on soils and paving materials resulting from the use of non-potable water for their processing. ; c. Testing of the impact of using nonpotable water in the processing of soils and paving materials on the environment.
