Abstract
An infill layer for use in an artificial turf system is provided. The artificial turf system may include a pile fabric having a turf backing and a plurality of turf fibers extending upwardly from the turf backing. The infill layer may include particulate material disposed upon an upper surface of the turf backing and between the turf fibers. The infill layer may advantageously comprise ceramic support material in one or more courses. The ceramic support material may also be combined with other hard particles and/or with resilient particles in the infill layer. Alternatively, recycled support material or support material having a substantially consistent size and shape may be used instead of ceramic support material.

An artificial turf system comprising:
- a pile fabric having a turf backing and a plurality of turf fibers extending upwardly from the turf backing;
- an infill layer of particulate material disposed between the turf fibers upon an upper surface of the turf backing, the infill layer comprising:
- a base course of ceramic support material disposed on an upper surface of the turf backing;
- a middle course of sand, rocks or other hard particles disposed on the base course;
- and
- a top course of resilient particles disposed on the middle course.
