THE USE OF DISTRESS PREDICTION SUBSYSTEMS FOR THE DESIGN OF PAVEMENT STRUCTURES

This report presents the results of an investigation designed to develop procedures for predicting distress in asphalt pavements using mechanistic parameters of stress, strain, and deformation. The specific forms of distress considered were fatigue cracking, permanent deformation, and low-temperature cracking. Two computer programs were developed, one for fatigue cracking and permanent deformation (PDMAP) and one for low-temperature cracking (COLD). The programs should provide capability in simulating the occurrence of pavement distress and can be used in pavement management systems, diagnostic investigations, formulation of design criteria, and preparation of material and construction specifications. Field verificaton of such programs is limited, since most of the available field data were used to develop the damage prediction models. The programs are considered implementable and have been successfully executed on state highway department computer equipment. One of the conclusions of the investigation is that field verification is necessary in order to calibrate the basic predictions to local conditions. /Author/
