Design and Construction of PCC Pavements, Volume III: Improved PCC Performance Models
Primary Topic: Rigid Pavement
Description: This study was conducted to evaluate and analyze portland cement concrete (PCC) pavements in order to develop recommendations for the design and construction of long-lived concrete pavements. It involved a detailed evaluation and analysis of the PCC pavement data in the Long-Term Pavement Performance (LTPP) database using a variety of methods to determine the design features and practices that have beneficial effects on long-term performance. Emphasis was placed on identifying those specific design features that can be included during design to improve the performance of PCC pavements under various combinations of environmental and traffic loading conditions, and for different subgrade support conditions. The study focused on the development of practical recommendations that can be implemented by highway agencies to increase pavement life.
This volume describes and provides information on improved pavement distress and roughness prediction models that were developed as part of the study. A key focus was to develop distress and roughness prediction models that incorporate mechanistic principles but are still practical for use by State highway agencies.
This report is the third in a series of three volumes on the study. The other volumes are as follows: FHWA-RD-98-052, Vol I Summary of Design Features and Construction Practices That Influence Performance of Pavements and FHWA-RD-98-127, Vol II Design Features and Practices that Influence Performance of Pavements.
