About the research



The Pooled Fund study “Effects of Implements of Husbandry (Farm Equipment) on Pavement Performance” is a project that started in 2007 and sponsored by the Minnesota Department of Transportation, Iowa Department of Transportation, Illinois Department of Transportation, Minnesota Local Road Research Board, and partners in the agricultural industry. The objective of this study was to investigate the effects of farm equipment on the structural responses (stresses and strains) of flexible and rigid pavements. Furthermore, the project aimed to quantify the pavement damage caused by heavy farm equipment compared to the damage caused by a typical 5 axle, 80 kip semi-truck. This research was conducted experimentally, using test sections at the Minnesota Road Research facility (MnROAD), and analytically, using models developed for structural analysis.
