RESPONSE AND DISTRESS MODELS FOR PAVEMENT STUDIES

Results of a detailed study to select mathematical and other models for the prediction of significant distress for flexible, composite, and rigid pavements are presented. Rigid pavements were subdivided for study into nonreinforced jointed concrete pavements (JCP), jointed reinforced concrete pavements (JRCP), and continuously reinforced concrete pavements (CRCP). The models selected are to be used in establishing optimal material properties for zero-maintenance pavements. The published results of field surveys and other experience were used to identify, for each type of pavement, distresses that cause considerable maintenance or loss of serviceability. Material properties that influence the occurrence of significant distresses were then identified, and theoretical or empirical models were selected to predict these distresses by using material properties and other engineering parameters. The distresses found to be most significant for these studies were (a) fatigue cracking for all types of pavement, (b) rutting and reduced skid resistance for flexible and composite pavements, (c) reflection cracking for composite pavements, (d) low-temperature cracking for flexible pavements, (e) spalling for all rigid pavements, (f) faulting for JCP and JRCP, (g) low-temperature and shrinkage cracking for JRCP and CRCP, and (h) punchouts and steel rupture for CRCP. The models considered, the context in which they are to be used, their attributes and limitations, and those finally selected for the study of specific distress for specific pavement types are briefly described.
