| 摘要： | Due to safety concerns associated with friction testing on both high and low-speed facilities, testing at variable speeds has been previously investigated by the Florida DOT. The American Society for Testing and materials (ASTM) has endorsed this concept with the publication of a standard method for the calculation of the International Friction Index (IFI) as described in ASME E 1960. Previous research conducted by the Florida DOT and the principal investigator has demonstrated that a 64 kHz non-contact, laser measurement system can provide a repeatable and accurate measure of pavement macro-texture in terms of Mean Profile Depth (MPD) with ASTM E 1960. The report summarizes the results of an effort to 'harmonize' such texture and skid-resistance measurements in Florida. |
