This report reviews the practices for roughness measurement and the unique features of urban and low-speed roadways, and it evaluates the use of existing inertial profilers for such measurements. The report also proposes revisions to AASHTO standard specifications and practices addressing inertial profiler certification and operations. The information contained in the report will be of immediate interest to state materials and pavement engineers and others involved in the different aspects of pavement condition monitoring and evaluation.
