Materials Characterization and Analysis of the Marquette Interchange HMA Perpetual Pavement
This project focused on the characterization of materials used to construct the Hot Mix Asphalt (HMA) perpetual pavement within the Marquette Interchange and on the analysis of collected pavement response data to investigate the interactions between materials, environment, and traffic loadings. While these pavements are designed for a service life in excess of 50 years, to date there is insufficient field data to confirm this performance expectation. To help bridge this knowledge gap, this study included a mechanistic-empirical appraisal of HMA perpetual pavement to provide predictions of key performance indicators over a fifty year service period. Laboratory testing was conducted following appropriate AASHTO testing protocols to provide valuable data to characterize the HMA, unbound aggregate and unbound soil pavement layers. This data was used to develop Level 1 HMA inputs to the current version 1,003 of the Mechanistic-Empirical Pavement Design Guide (MEPDG) and to better characterize the unbound aggregates and soils during Level 3 analysis. Weigh-In-Motion (WIM) data obtained as part of WHRP Project 0092-06-01 was analyzed to develop site-specific inputs characterizing the heavy axle loading spectra this pavement facility.
