Vehicles can leave tracks or ruts in turfgrass especially if the traffic is frequent or the soil is moist. However, mats, grids, meshes, or pavers which distribute the weight of a vehicle over a larger "footprint" may protect the turfgrass crown from injury and soil from compaction/rutting while providing for storm-water infiltration and less runoff than hardscapes. Seven turfgrass traffic injury abatement systems: GrassPave2, The Grid System, Permaturf, Ecogrid, Drivable Grass, Sof' Path, and Ground Protection Mesh were evaluated using 4’ x 4’ plots on a 2" base that was 75% sand, 20% Axis, and 5% organic matter which were seeded with Riviera bermudagrass and maintained at 0.5”. Traffic was inflicted 1 time/week by making 4 passes with a Caterpillar 216B skid steer loader. Visual turfgrass quality, injury, and visibility of the traffic injury abatement system estimates based on a 1-9 scale were taken weekly. Chlorophyll content was measured weekly with a FieldScout CM1000 from 10 locations in each plot inside and outside the rut. All treatments on the 2” sand base performed better than the native soil control.
