The Little book of Profiling : Basic Information about Measuring and Interpreting Road Profiles

High-speed road profiling is a technology that began in the 1960's when Elson Spangler and William Kelly developed the inertial profilometer at the General Motors Research Laboratory. Some users still call high-speed profilers by their early name: GMR Profilometers.In the past decade, profiling instruments have become the everyday tools for measuring road roughness. The majority of States now own road profilers. A substantial body of knowledge exists for the field of profiler design and technology. There are also many proven methods for analyzing and interpreting data similar to the measures obtained from profilers. However, there has not been a single source of information about what you can do with a profiler. Users have instructions provided by the manufacturers to operate the equipment, but little else to go on.
