A COORDINATED DESIGN PROCEDURE FOR FATIGUE, RUTTING AND LOW TEMPERATURE CRACKING IN ASPHALT PAVEMENTS

Asphalt concrete pavements generally exhibit three major types of structural distress: permanent deformation, fatigue cracking and low temperature cracking. An economical pavement design will minimize the degree of distress. In order to arrive at such a design, a method is needed for predicting the amount of each type of distress for any given set of conditions and range of design alternatives. This paper presents a coordinated method for predicting the amount of permanent deformation, fatigue and low temperature cracking at various stages in the life of a pavement. It can form part of an overall design method and can be used to screen out those alternatives likely to have "accelerated" deterioration. The method is approximate. It represents a simplification of more in-depth laboratory and analytical investigations, which were themselves subjected to extensive sensitivity analyses. The result is a relatively simple set of equations, which have been computerized and which work from a common set of data inputs. The computer program used to make the predictions is efficent and can consider a large number of design alternatives at relatively low cost. Verification of the distress predictions from this model have been made using data from various highways and test roads. (TRRL)
