RESEARCH PAYS OFF: KANSAS SMOOTHS WAY TO COST-EFFECTIVE ROAD PROFILES

The Kansas Department of Transportation (KDOT) was interested in extending the accuracy and efficiency of its 26 existing manual profilographs without incurring the prohibitive costs of replacing all units with expensive automated systems. A joint research effort by KDOT and Kansas State University resulted in the development of an automated method of capturing and analyzing the data collected with manual profilographs. Use of the semi-automated system has provided objective analysis of data and eliminated variations due to operators, as well as resulted in significant reduction in time required to analyze the roughness data. A total of $45,000 in labor costs has been saved in 3 years. Smoother pavements are expected to require less maintenance, with an estimated maintenance cost savings of $10,000 the first year and an increase in savings for the life of the pavements. Motorists also benefit through reduced wear on vehicle components, reduction in driver fatigue, and improved road safety. Further details are provided in this article.
