APPLICATION OF THE MECHANISTIC ANALYSIS PROCEDURE TO PAVEMENT REHABILITATION: TWO CASE STUDIES. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN
Mechanistic analysis and design procedures have become an important part of highway pavement design and, certainly in South Africa, have led to significant improvement and advances over earlier designs. This is due, in large part, to the better understanding of material behaviour in pavement structures gained from many years of accelerated testing using the Heavy Vehicle Simulator. With the development of the road infrastructure, present emphasis is turning towards rehabilitation of existing major roads and, consequently, to the application of mechanistic analysis in rehabilitation design. The major aim is, of course, implementation of the most appropriate rehabilitation action. This requires, firstly, a meaningful assessment of the existing structural condition of the road and, secondly, the realistic appraisal of possible alternative rehabilitation measures. This paper gives details of two recent rehabilitation investigations, and illustrates the application of the South African mechanistic design methods in assessing both the existing structural condition and the subsequent rehabilitation measures of the pavements. The two case studies demonstrate the use of conventional methods of initial pavement assessment and the use of an accelerated trafficking test programme. The rehabilitation recommendations were adopted for each road and it is concluded that the procedures used enable a rapid assessment of the most appropriate rehabilitation strategy with a high degree of confidence.
