Abstract

Waste or scrap materials cause a lot of environmental problems and lead to economic problems. To
minimize these problems, it is necessary to find safe ways to reduce the harms on environmental issues and on the
economy accompanying with accumulated large wastes. This study introduces an attempt to improve sandy soil
using a new additive in form of waste tires chips instead of conventional kinds used in the soil stabilization.
Different percentages of waste tire chips are hand mixed with dry sand as a trial to stabilize the sand with local
cheap materials. Some geotechnical properties of composite specimens of (soil + tire chips) were studied and the
main findings of testing approved the ability to stabilize sand effectively using scrap tire chips. Shear strength of
sand was increased as a result to increase both friction angle and cohesion after adding tire chips to sand. A
significant reduction in specific gravity and maximum dry density with a little reduction in optimum moisture
content was marked with increase tire chips content in sand due to the low unit weight of tire chips. Analyzing the
results gained from CBR test showed that sand stabilized with tire chips gave CBR more than about 1.6 times
compared with pure sand which means the load bearing capacity of treated sand is increased due to increase the
physical bonds between sand particles and tire chips.
