Survival Analysis of Concrete Overlays on Low-Volume Roads in Iowa

Abstract: Concrete overlays are an important component of Iowa’s rural road network. More than 2,000 centerline miles of concrete overlays have been paved in Iowa over the last few decades, including many overlays on low-volume roads serving 400 vehicles per day or less. In this study, a survival analysis was performed using automated pavement condition data collected on Iowa’s concrete overlays to obtain a probabilistic assessment of concrete overlay service life, paying particular attention to the performance of overl… Show more

“…Overlay analysis means that through ArcGIS software, elements of different spaces are overlaid and attributes are assigned in the same coordinate system using identification, spatial connection, intersection, and other tools, and the generated new layer of spatial data contains the spatial attributes of all layers (65)(66)(67). This study mainly uses ArcGIS software to overlay the spatial distribution data of epidemic preparedness facilities, population, and road network in Wuhan, and to compare and analyze their spatial distribution characteristics.…”
