• Abstract:
  This research aims to discover the post-construction performance impact of DB delivery methods on pavement projects. The study uses road smoothness in terms of the International Roughness Index (IRI) as the performance metric of choice to gauge ride quality. The authors analyze data from 21 projects in two state DOTs using a Linear Mixed Effects Model (LME). The results from this study indicate DB projects show improved performance, compared to traditional DBB projects.
