| Abstract/Contents: | "An innovative testing apparatus was developed to approximate the rapid load applied by an athlete's shoe or horse's hoof to a turfgrass surface. Unlike earlier test methods, the apparatus applies a multi-dimensional, variable inclined, eccentric load to a footing. Replicated investigations of various root zone mixes and profile constructions were conducted and the deformability, mode of failure (divoting), and multi-directional bearing capacity compared for each. The investigation was extended to include testing of root zones with an established Lolium perenne-Poa pratensis turf cover. The findings showed that root zone materials and profile constructions that have very similar bearing capacities when subject to vertical, centrally applied loading, i.e. the conventional test procedure, may exhibit very different performances under variable inclined, eccentric loading. The latter more nearly simulates the multi-directional loads imposed by an athletes' shoe or a horse's hoof. Inclusion of the three-dimensional, interlocking Netlon mesh elements increased the bearing capacity of all root zone mixes and favourably altered the mode of failure, without adversely increasing the surface stiffness. This increased strength without loss resilience is of major significance to equestrian and player safety. The test methods and simulation apparatus provide a means of quantitatively assessing root zone stability and improving root zone profile design to optimise the stability as well as agronomic performance for a wide range of turfgrass applications." |
