Abstract:COLORMAP is a signal processing system for ground-penetrating radar (GPR) data. It is intended to convert the raw GPR signals into information useful for pavement engineers. This system has been in use by TxDOT since 1996. This report provides an updated user's manual for COLORMAP together with a discussion of the new on-line help menus. These menus are based on a series of case studies conducted in Texas. They illustrate the influence of subsurface defects, unusual materials, and construction quality control problems on GPR signals.
