TESTS USED IN PROJECT LEVEL FLEXIBLE PAVEMENT REHABILITATION STUDIES

This paper gives guidelines for the use of tests and their interpretation in the various phases of flexible pavement rehabilitation design as currently adopted in South Africa. The procedure advocated involves a systematic approach to the investigation, evaluation and analysis of the existing pavement. In the recommended procedure use is made of past pavement behaviour and pavement condition, thereby making possible an early assessment of additional information needed. Much emphasis is placed on the optimum utilisation of available resources in designing the best applicable remedy to an existing problem. The need for an effective system for evaluating roads when establishing rehabilitation priorities is recognized. This paper gives a comprehensive list of criteria for parameters measured on a routine basis on South African roads. The procedure suggested allows the condition of pavements to be expressed in comparable terms. Information on the development and use of some new and specialized tests which are used in pavement rehabilitation is given in an appendix. (Author/TRRL)
