Stabilizing the Excavation Materials to be used in Fill Layers

Daily increase in the amounts of soil and wastes produced by excavation and demolishing of the old buildings in the urbanworn out textures has caused great problems in large cities. The environmental issues due to the irrelevant and non-technicaldisposal of waste materials have attracted attention of researchers with the aim of recycling and use of these materials inthe civil and construction activities. Old buildings constitute a significant portion of Sharestan Razavi Blvd in Mashhadwhich after demolishing of these buildings the area in this section is covered by the backfill materials and those remainedfrom the demolishing of the buildings. In this research, maximizing use of the available materials and minimizing thetransportation work as an execution order have been under focus of attention. Also through performing various tests, thepossibility of recycling, stabilizing and implementing these materials at underlying layers of Sharestan Razavi Blvd hasbeen evaluated and the results are presented.
