oa Interim : Interdisciplinary Journal - Sustainable approach to upgrade low volume roads in Petrusville



Research undertaken in Petrusville and Philipstown was to illustrate how nonconventional materials performed as a sub-base. Roads investigated in this research paper were classified as light or low volume roads where the daily traffic equalled to 100 vehicles per day. Main objectives was to achieve a reduction in the overall life cycle cost, vehicle operating cost and the depletion of nonrenewable resources for the roads. The outcome the road authorities and the different stakeholders wanted to achieve was that non-conventional materials can replace good quality road construction materials if the approach is cost effective and sustainable in the long term.
