| 摘要： | This report addresses important factors associated with the design of steel reinforcement in terms of layer configuration, bond characteristic, climatic effect, and others relative to an assessment of the suitability of the CRCP 8 program to represent and predict steel stresses in CRC pavement systems. It was necessary to instrument an actual section of CRC pavement for concrete and steel strains as they fluctuated under climatic and seasonal changes. The steel rebars were instrumented in a manner that would limit disturbance of the bond between the steel and the concrete, yet allow for precise measurements of the steel strain at various distances from the crack face. Other field sections containing Grade 70 steel were also included in this study. Crack spacing and crack width data were collected and reported. |
