• 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
