| 摘要： | This report presents the findings of a research study conducted to evaluate and demonstrate real-time smoothness measuring technologies for concrete paving. Real-time smoothness refers to measuring and evaluating the concrete pavement surface profile during construction, somewhere along the paving train while the concrete surface is still wet (plastic). These measurements are then used to check for objectionable profile characteristics, things that are known to happen in projects that can affect pavement smoothness. With this information, paving operations can be adjusted on the fly. Ideally, deviations are detected in real time and corrections are made such that the final hardened concrete surface can avoid being ground to achieve the smoothness requirements. The work under this study was executed in three distinct but connected phases. Each phase served to evaluate promising and emerging technologies with the potential to measure real-time smoothness. Draft model specifications and guidelines were developed to facilitate evaluation and implementation of these technologies by state highway agencies. Phase 1 focused on identifying all potential technologies by contacting leading transportation agencies, paving contractors, paving equipment manufacturers, and representatives of concrete pavement associations. Numerous real-time smoothness-measuring technologies were reviewed, and three of these were recommended for further evaluation; however, only two were available to participate in this study. Three additional technologies were identified, but not recommended for subsequent evaluation because they lacked technical maturity or a proven history on concrete paving applications during the time frame for this study. Phase 2 consisted of a thorough field evaluation to evaluate objectively the most viable realtime smoothness measuring technologies identified during Phase 1, the GOMACO Smoothness Indicator (GSI) and Ames Engineering Real Time Profiler (RTP).
