| 摘要： | Pavement roughness is an important characteristic monitored by many road agencies. It is used as an indicator of road performance and also for feasibility studies. In developing countries, the most common method of recording road roughness is the use of response-type roughness meters. These are instruments that measure the displacement of the vehicle chassis relative to its axle. Because vehicles respond differently to roughness, it is necessary to calibrate them against a standard roughness measure. Calibrating roughness meters against the international roughness index, profiling test sections, undertaking a calibration experiment, and analyzing the calibration data are addressed. |
