dc.description.abstract Paper presented at the 32nd Annual Southern African Transport Conference 8-11 July 2013 "Transport and Sustainable Infrastructure", CSIR International Convention Centre, Pretoria, South Africa. en_US
dc.description.abstract The design and implementation of a pavement rehabilitation project in a Central Business District (CBD) of a city poses numerous challenges. These challenges include the high design traffic, depth of pavement rehabilitation, presence of many services, traffic accommodation, pedestrian accommodation, construction period, construction materials, final level of construction, environmental and social impact and sustainability. The paper presents a case study of an innovative pavement design and construction process for the rehabilitation of Harvey Road and Hanger Street in Bloemfontein, South Africa. The paper addresses the practical rehabilitation option, which met the challenges faced on the project, as well as the construction materials mix design details, construction methods, time frames during construction as well as a cost comparison between conventional deep rehabilitation pavements and the innovative rehabilitation pavement. The design incorporates a bitumen emulsion stabilised crushed stone base, which includes reclaimed asphalt, paved with a paver on top of a mechanical stabilising grid. en_US
