ABSTRACT
Physical and water properties of silt loam from the area of planned football field were tested and compared with analogous properties of several composites made in laboratory conditions from the collected material with a dominant sand share. The research was conducted in a view of silt loam and its composites usefulness for constructing a carrying layer of football fields. Water permeability of silt loam and composites, as well as retention abilities were tested. The created composites met the water permeability requirements specified by DIN 18035 standard for constructing carrying layer of football fields. On the other hand, silt loam without sand admixture did not meet the requirements, but revealed a high retention capacity and water availability to plants. Among the composites the best retention capacity characterised the mixtures with the biggest content of silt loam, but the best water availability was registered in composites with medium content of silt loam from the football field area. The obtained results may be useful for more precise determination of the standards for grain size distribution of the composites used for constructing the carrying layer of a football field.
