Annually over a million scrap tires are generated in Saskatchewan which in the past have been disposed of in landfills and streams. At the same time, Saskatchewan has also experienced a drastic increase in truck traffic on roadway infrastructure that is ageing. This has resulted in the need for the construction of new roads and the rehabilitation of existing ones. In addition, significant changes in climatic conditions have also been recorded including high road substructure moisture problems and an increased number of freeze thaw cycles, both of which can cause cracks and ruts on road surfaces. Previous research work adopted the use of shredded tire material as a drainage layer to mitigate frost and moisture problems. Test sections built using this technology performed well in drainage and frost insulation but performed poorly in providing structural support. This research examines the possibility of improving the structural performance of shredded tire road systems through laboratory and field evaluation.
