| 摘要： | The high-speed measurement of accurate pavement surface deflections under a moving wheel at a network-level still remains a challenge in pavement engineering. This goal cannot be accomplished with stationary deflection-measuring devices. Engineers recognize the usefulness of pavement deflection data to evaluate and monitor pavement response and existing pavement structural conditions. Network-level studies of pavement structure are being performed but have major limitations such as lack of accurate measurements, no true deflection is measured at any point, complexity, and safety concerns. The purpose of this project is to develop a laser measuring system for network-level studies that continuously moves along the pavement at speed above 10 mph. |
