STATISTICAL QUALITY ASSURANCE IN HIGHWAY ENGINEERING IN SOUTH AFRICA

This paper examines the first large-scale application of process and acceptance control plans to a major road construction project in South Africa. The acceptance control scheme used and its background are out-lined, and certain controversial features of the scheme are discussed. The variability of typical South African construction materials and processes is indicated. Some economic consequences of the use of the plan are also reported. Because the average quality of the work was well above the minimum standard required, a fully conclusive assessment of the financial advantages or disadvantages of the scheme is not possible. Because of this, a comparison was made between the acceptance decisions of the specific scheme discussed, and those of the engineering judgment approach. It is concluded that the use of the statistical method leads to more consistent interpretation of results, and the contained use of this scheme on highway projects is recommended. /Author/
