Advancing pavement management techniques in South Africa’s largest city, Johannesburg

Typical areas requiring innovative techniques in the managing of a City’s roads and pavement management systems include: the accuracy and completeness of the road map; the correct location of roads in the field when street names are missing; integrating the optimum maintenance and rehabilitation analysis and determination of roads such as motorways and arterials which deteriorate mainly as a result of traffic loading and collectors and suburban roads which deteriorate mainly as a result of surface ageing; upgrading and maintenance programming of unpaved roads which can deteriorate overnight as a result of rainfall. This paper describes these areas in more detail and the techniques and innovations used to overcome these providing an improved platform for the way ahead. Techniques used include aerial photography, latest GIS conflation techniques, Global Positioning Systems, electronic field data collection, integration of windshield visual assessments and instrument measurements such as roughness and deflection testing, as well as appropriate data collection and analysis techniques for unpaved roads.
