Most cities suffer the consequences of the phenomenon of the spread of construction, demolition, maintenance and road wastes. These wastes are estimated at millions of tons, so their accumulation has become a burden on the environment and disposal of the most complex environmental problems facing the world today, therefore the aim of this study was to eliminate these wastes and to make use of them and to achieve this goal, where were chosen for use in road paving (base or sub base) as an alternative to natural aggregate. As for the compaction importance of the first major role in the construction of roads, the testing of the compaction was examined mainly. Cement, site soil and natural aggregates were used as additives to the constructional wastes, each with different weight ratios. Through the results find the best density was obtained when the cement is added to the construction waste and then when added local soil. This study indicates the possibility of taking advantage of the construction and demolition wastes as an alternative to natural aggregate for road paving. It is also possible to take advantage of it in many different civil engineering applications such as treadmills for floors, pedestrian paths, parks, public gardens sidewalks, etc. These wastes may be less than the cost of disposal by traditional methods and have good environmental and health benefits at least in the long run.
