Mechanistic-Empirical Evaluation of the Mn/Road Mainline Flexible PavementSections. Cooperative Evaluation of Mn/Road Test Results to Illinois Conditions

摘要

The purpose of this study was to use Mn/ROAD mainline flexible pavement data toverify, refine, and modify the Illinois Department of Transportation (IDOT) Mechanistic-Empirical (M-E) based flexible pavement design procedures and concepts. Illinois has used M-E design procedures for the design of full-depth asphalt concrete (FDAC) and conventional flexible pavements (CFP) sections since the late 1980's. The Mn/ROAD project has 40 test cells that are 500-feet long. The cells represent a wide range of pavements types, with varying combinations of surface, base, subbase, drainage and compaction. paving materials characterization was addressed through laboratory and field testing programs. Laboratory testing was performed at the University of Illinois, MnDOT and the University of Minnesota. Field characterization of the paving materials was performed through FWD and DCP testing.
