摘要

In 1993, a special pavement demonstration project was constructed in Detroit on NB I-75 to evaluate the design features of some highly acclaimed European rigid pavements. The Michigan Department of Transportation (MDOT) and the Federal Highway Administration (FHWA) agreed to this project after an extensive inquiry of European pavements, including a 1992 technical tour of pavements in Germany and Austria to gain insight into their specific design features and construction practices for duplication with the Detroit project. MDOT has monitored the projects performance for the past twenty years since construction. The results from the I-75 European project continue to generate nationwide interest amongst pavement enthusiasts. This report is a compilation of the condition data of the Euro-pavement since its construction. Because MDOT considered this demonstration project a valuable research opportunity, a rigid pavement control section was included on NB I-75 adjacent to the one-mile long Euro-pavement. The control section represented MDOT's standard rigid pavement design used during that era. This report also documents preservation contract work performed on both pavement sections in 2008 to repair pavement distress to extend their respective service lives. The report also describes investigative work into the cause of the distress that initiated the 2008 preservation project, as well as investigation of further distress observed in the Euro-pavement section since 2008. Today, both pavements have relatively similar ride quality values (RQI/IRI). The Euro-pavement section, however, is showing signs of surface delamination which appears to be originating at the transverse joints and propagating outward toward mid-slab, as well as intermittent longitudinal cracking in the right wheel path. A distinct performance trend has not yet developed for either pavement section to estimate a definitive service life expectancy. In the interim, MDOT has benefited from the project by using its limited results to enhance its present rigid pavement design in efforts to extend its service life.
