This study aims to investigate the effect of corrective treatments on the life cycle. An optimum analysis is conducted by using the genetic algorithm to find the optimal M&R plan along 10 years analysis period for each pavement sector where the objectives are minimizing the total costs and maximizing the average performance along the 10 years. Two maintenance policies (MPs) ... إقراء المزيد

Prediction of water amount and its movement through natural expansive soils due to ground water or water of irrigation is very important for engineers. This movement may affect drainage efficiency, pollutant movements, safety of constructions, canals lining and design of public and water structures. Present research is carried out to investigate; 1) Change of physical properties of swelling soils due ... إقراء المزيد
