During a pilot study at a Thoroughbred racetrack, information was collected to include weather conditions and track surface properties (moisture content, composition, strength, and coefficient of friction between surface and hoof). Measured weather variables did not correlate to any pattern of horse injuries of breakdowns. Surface moisture content was variable, whereas the moisture content of the compacted cushion was constant. Track surfaces around the starting chutes were more compacted than were other areas of the track. Next to the rail, track surface was softer than the surface toward the middle of the track. The coefficient of friction between a hoof and the surface was not affected by location or surface moisture content.
在一项针对纯种赛马场的试点研究中，收集了包括天气状况和赛道表面特性（含水量、成分、强度以及表面与马蹄之间的摩擦系数）在内的信息。测量的天气变量与任何马匹受伤或摔倒的模式均无关联。表面含水量是可变的，而压实垫层的含水量是恒定的。起跑滑道周围的赛道表面比赛道其他区域压实程度更高。靠近围栏处的赛道表面比赛道中间区域的表面更软。马蹄与表面之间的摩擦系数不受位置或表面含水量的影响。
