Abstract
An artificial turf field comprises a mat with artificial grass stitched to the mat and rubber granules combined with powdered latex or other suitable powdered binding agent activated by water. Mats with the artificial grass affixed are laid on an athletic field. Rubber granules mixed with a bonding agent and the coated rubber granules are poured over the mats and raked until a depth of ½ to ¾ inches is achieved. Water is then misted onto the surface activating the bonding agent. The first layer is allowed to set. The first level of infil material will be bound particle to particle, to the grass and to the mat by the agent, thus ensuring a stablized shock absorbency pad. Additionally, the stabilized layer eliminates substantial migration of loose infil material. Next, uncoated rubber granules are applied to the field and raked in until only the top of the grass shows providing a finished appearance, the feel of a playing surface that is uniform, and a surface that is prevented from becoming thicker and harder in various places due to migration. The artificial grass fibers are brushed to fibrillate the ends of the artificial grass fibers.
