| 摘要： | This report compares pavement profile data collected by 4 profilometers used by the Strategic Highway Research Program's Long Term Pavement Performance Program. Three of these were identical; the sensors of the fourth were closer together. The purpose of the comaparison is to determine if the profilometers can collect repeatable data with respect to each other as well as individually at a given site, and whether they are collecting accurate data (determined by comparing the International Roughness Index computed from profilometer data with that computed from Dipstick data). |
