| 摘要： | There are over 48,300 km of continuously reinforced concrete (CRC) pavements in the United States. Many of these pavements are more than 20 years old and have provided excellent performance over the years. Much of the CRC pavement technology has developed through experience. This and the recent use of new design features (i.e., tied concrete shoulder, permeable cement treated base, and epoxy-coated steel) identified a need to conduct a study to evaluate performance of existing CRC pavement sections. A national pooled-fund study administered by FHWA and aimed at updating the state of the art of the design, construction, maintenance, and rehabilitation of CRC pavements was recently completed. As part of the study, a comprehensive field investigation of 23 in-service CRC pavements was conducted to study the effects of various design and construction features on performance of CRC pavements. The investigation included crack mapping and distress survey, profile and roughness measurement, falling weight deflectometer testing, and materials sampling and testing for 305 m long in-service test sections. The key findings of the field investigation program as they relate to CRC pavement design and construction are presented. |
