Over two hundred pavement sections in Kentucky have been periodically measured for pavement roughness over a period of several years. This pavement service-life historical data can be used to assess quality of construction, pavement service-life, present and anticipated pavement condition. Road users perception of ride quality can be related to these measurements. Response-type road roughness measuring systems have been used to collect roughness measurements and correlation studies have been performed to relate measurements from current systems. Several factors influence pavement roughness. An early factor is construction workmanship. Other factors are traffic loading, environment, geology, and age.
