| 摘要： | This report defines critical accuracy requirements for a reference profiling device. The work was performed under a Federal Highway Administration (FHWA) pooled fund study TPF- 5(063) 'Improving the Quality of Pavement Profiler Performance.' The requirements include the waveband of interest, the required accuracy, the sampling and footprint requirements, the method of profile comparison. A tentative testing program is defined for benchmarking the accuracy and repeatability of profiles from candidate reference devices, and their longitudinal distance measurement accuracy. A method is also recommended for comparison of profiles from production profilers to the output of reference profiling devices. |
