| 摘要： | A study has been conducted to evaluate and analyze portland cement concrete (PCC3 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 statistical techniques to determine the design features and construction practices diat have a beneficial effect on long-term performance. The study focused on the development of practical recommendations that can be easily implemented by highway agencies to increase pavement life. This volume describes and provides information on design features and construction practices that improve pavement performance. A key focus was to develop canonical discriminant functions that can be used to discriminate between groups of pavements in the sense of being able to tell them apart. The pavements were grouped according to their performance classification, namely, above expectation, as expected, and below expectation. The canonical functions consist of linear combinations of the variables that describe and quantify ^ pavement design features, site conditions, and construction practices. This report is die second in a series of three volumes on die study. The other volumes are as follows: FHWA No. VolNo. Short Title FHWA-RD-98-052 1 Summary of Design Features and Construction Practices That Influence Performance of Pavements FHWA-RD-98-113 HI Improved PCC Performance Models |
