Abstract/Contents:"Baseball is played primarily on the infield skin, which comprises ~0.1 ha of compacted bare soil. Without stabilization by roots, loads applied to the infield skin by athletes and baseballs are borne solely by the soil skeleton. Infield soils are commonly manufactured by blending washed sand with a clay soil. For any mixture there exists a unique range of water content over which the soil is suitable for play. The lower extent of this range corresponds to the water content at which the soil transitions from ductile to brittle behavior. Below this water content, the soil tends to fracture into chips, possibly inducing an unpredictable ball response. The upper water content boundary corresponds to the minimum shearing resistance required to provide safe footing.Two laboratory methods were developed to assess the performance of infield soils. The first method employs a pneumatic apparatus to simulate shoe-to-surface interactions. This cleat-mark method identifies the water content at which surface disturbance is minimized. The second method employs the unconfined compression apparatus to measure the shear strength of cylindrical soil specimens having a range of water contents. A series of sand-clay mixtures were tested using the new methods. Ductility and shear strength were found to be a function of both clay mineralogy and sand content. Smectite clays yielded the stiffest mixtures, followed by those containing kaolinite and illite. Maximum shear strength while in the ductile state occurred at intermediate sand content (55-70%). High-plasticity clays such as smectite may expand the range of water content over which an infield mix is playable. However, field managers must weigh this benefit against the extreme hardness of these mixes when dry and the potential for shrinkage-induced cracking. This research will help develop a more mechanistic approach for designing and evaluating infield soils."
