Kentucky Transportation Center Research Report
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 based inertial profiler from the Kentucky Transportation Cabinet (KYTC) and a Face Rolling Dipstick. Phase Two was a continuation of Phase One with 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 …
