In 1983, a section of the M2 motorway in Johannesburg was showing signs of severe distress and the Johannesburg City Council commissioned the National Institute for Transport and Road Research to evaluate the pavement structure and recommend remedial measures.
Alternative methods of rehabilitation were considered and reasons are given for the chosen method. This basically consisted of removing the existing structure at night using a milling contractor and resurfacing departmentally during the day. The work was well planned and given wide publicity.
The method used for controlling traffic and details of the rehabilitation work together with unique problems encountered and final costs are discussed in the paper.
