• Abstract:
  Phase 1 of this project was conducted to better understand the cause of pavement failure under
  
  actual traffic loading and environmental conditions. A 1,000-ft. long experimental pavement
  
  section was constructed on I-35 in McClain County and was instrumented for field data
  
  collection. The test section was designed to fail in a relatively short period of time under heavy
  
  interstate traffic. After approximately four years (from 2008 to 2012) of exposure to continuous
  
  interstate traffic and environment, the test section experienced significant rutting but no fatigue
  
  cracking. Therefore, the funding agency decided to monitor the test section for two additional
  
  years (from 2012 to 2014) as part of Phase 2 of the project. Additionally, a need for predicting
  
  distresses (i.e., rut, based on the site-specific data) using the Mechanistic Empirical Pavement
  
  Design Guide (MEPDG) software was expressed. In Phase 2 of this project, the quarterly field
  
  testing (FWD, rut measurements, roughness measurements, and crack mapping) was
  
  performed on a quarterly basis. Also, the weekly downloading of traffic data and data processing
  
  were performed to allow updating of the rut prediction models developed in Phase 1 of this
  
  study. Site-specific (Level 1) input parameters for traffic, climate and materials were developed
  
  in this study. Furthermore, the rut prediction models in the MEPDG software were calibrated
  
  using the developed input parameters and measured rut depths from the test section.
  
  Laboratory tests (Hamburg rut, four point beam fatigue, volumetric properties, etc.) were
  
  performed on the extracted samples from the test section. Moreover, the contribution of different
  
  pavement layers to total rutting was assessed by a forensic investigation involving cutting full-depth trenches at three selected locations of the test section
