Abstract/Contents:"Athletic field root zones are built with high sand content materials primarily to maintain drainage and macroporosity with compaction. However, these materials can create problems due to their lack of strength. The objective of this study was to develop a better understanding of how particle size distribution and water content at compaction affect the strength and the hydraulic conductivity of high sand content root zones. One sand and one sandy loam textured soil were mixed in with various proportions to produce seven mixtures. The sand/soil mixtures were subjected to four tests: the standard Proctor compaction test, modified Califoria bearing ratio, saturated hydraulic conductivity, and pore size distribution. The sand/soil mixtures were compacted at (5%, 9%, 13% kg kg-1) for mixes containing 2%, 5%, 7%, 8% silt + clay and at five water contents (5%, 7%, 9%, 11%, 13% kg kg-1) for mixes containing 10% and 12% silt + clay, compacted at 5% water content, more than 100% increase in strength was observed over sand alone while maintaining hydraulic conductivity values of 19.0 and 8.5 cm h-1, respectively."
