Abstract:

This report provides two analyses for obtaining a quantitative means of rating the condition of railroad-highway at-grade crossings based on their measured roughness. Phase One of this report examined 11 crossings in the Lexington area by use of a laser inertial profiler from the Kentucky Transportation Cabinet (KYTC) and a Face Rolling Dipstick. Phase Two was a continuation of Phase One was 26 crossings examined using inertial profilers from both the KYTC and the National Center of Asphalt technology. Objective ratings based on rideability were obtained and wheelpath profiles were measured for each crossing. Several roughness indexes were computed from the measured profiles. A correlation between these indexes and subjective rideability ratings were examined in each study. Analysis of the data showed a tendency of objective ratings to decrease as roughness increases. this study found that highway inertial profilers are not an appropriate tool for determining roughness over short distances such as railroad crossings due to their application for testing of longer distances. It is anticipated that this report will be referenced for future research on this topic.
