This study involved the (a) selection of models suitable for predicting important distresses that previously have been observed on continuously reinforced concrete pavement (CRCP) and (b) determination of a set of material properties that will provide satisfactory performance for 20 years without maintenance and satisfactory performance for the next 10-20 years with normal maintenance. To accomplish this goal, the most important distresses occurring in CRCPs and the material properties that affect those distresses were indentified. Mathematical models to predict those distress by using the identified material properties were selected. A range of values for each material property was selected and resulting distresses were predicted. The distresses studied included fatigue cracking, punchouts, crack spalling, steel rupture, and low-temperature and shrinkage cracking. The mathematical models selected for the analysis were ELSYM5 for modeling fatigue cracking and CRCP-2 for modeling low-temperature and shrinkage cracking. Punchouts, crack spalling, and steel rupture were incorporated into the analysis of low-temperature and shrinkage cracking. Input values were selected for each model, and ranges of the material properties affecting distress were identified and used in the analyses. The results for each study are discussed, and practical criteria are cited to evaluate the level of material properties required to provide zero- maintenance performance. A set of material properties is identified, and the trade-offs on material properties are discussed.
