A Qualitative and Quantitative Assessment of Pavement Sections That Have Remained in Poor Condition For 5+ Years

Summary:

Within MnDOT’s pavement management system, the condition of some pavement segments had been rated poor for longer than five years. Ride quality index ratings are calculated in part using data acquired through pavement roughness measures. Researchers investigated these pavement segments throughout MnDOT’s eight regional districts and discovered that most of them were not in poor condition at all. Instead, anomalies in the segments, such as bridge and railroad crossing approaches, manhole covers or other urban characteristics, conveyed the impression of a rough ride but were not indicative of true pavement condition. Additional data to effectively assess and express these pavement segments’ true condition will be added to MnDOT’s system.
