This requires the removal of existing Institute of Technology, pavement surfaces. Recycling such construction waste has benefited Jimma University, Jimma, from economic to sustainability point of view and reduce the Ethiopia. exploitation of natural resources. The shortage of virgin aggregate supplies along with the increase in processing and hauling cost have encouraged the use of reclaimed material from the old structure as base course construction materials, and involved in regular practice in various countries around the world. Unfortunately, using Reclaimed asphalt pavement (RAP) is to take off in Ethiopia despite the current ambitions of road building program ongoing.
