Claim 0:
1. A synthetic turf system substantially at least partially free of crumb rubber infill and shock pads, comprising:
a water-porous backing layer;
a synthetic turf having a plurality of synthetic turf strands, wherein the synthetic turf is infilled with a plurality of sand particles and a plurality of cooling particles and spread at least partially uniform throughout the synthetic turf, and wherein the sand particles are at least partially coated with a super absorbent polymer, and wherein the synthetic turf is infilled with less than 1% of rubber particles or crumb rubber; and
a poured-in-place (PIP) rubber subsurface secured to the backing layer;
wherein the PIP rubber subsurface is not dispersed and provides buoyancy;
wherein the PIP rubber subsurface is poured with a mixture of rubber buffing and urethane aromatic polyurethane binder compacted and configured to deliver ASTM F1292 standards for impact attenuation for the synthetic turf placed on a playing surface;
wherein the binder constitutes 5 wt. % to 30 wt. % of the final subsurface;
wherein 5-35% of the volume of the compacted PIP rubber subsurface consists of air-filled cavities;
wherein the PIP rubber subsurface buffing comprises elongated strands having a length to width aspect ratio of at least and having a thickness between about 0.5 mm and about 2.0 mm and a length between about 3.0 mm and about 20.0 mm;
wherein the synthetic turf is attached to the PIP rubber subsurface using a rolled edge or a tucked edge.
