Effect of track maintenance on mechanical properties of a dirt racetrack: A preliminary study


College of Mechanical Engineering, University of Maine, Orono, Maine 04473


When Thoroughbred racehorses experience catastrophic injuries, the track surface is often discussed as a factor. The present study investigated the mechanical properties of the surface and found that significant changes in a track occur during routine maintenance. Questions regarding the relative importance of track variability and hardness require further investigation.
