To fill the voids of the elastomeric layers and provide a smooth, flat playing surface, one or more fill layers of dry fill material, such as silica sand, may be formed over the elastomeric layers. A color-fill system may be applied over the top fill layer, and one or more layers of a color mix may be applied over the color-fill system.

  • Publication number: 20030165357
    Abstract: A method for producing a thermoplastic filler for eliminating surface damage to concrete or asphalt surface is described, wherein the method comprises the steps of mixing stone chips, sand, a powdered material and a bituminous binding agent to a homogenous mixture which is in constant motion at a temperature of between about 180° C.-240° C., with a coolant being added subsequently to the mixture in a rapid manner thereby converting the mixture into a non-cohesive granulate of small pellets due to the high surface tension of the various constituents, and wherein the granulate can be heated to convert it to a free-flowing or spreadable filler having strong adhesive properties.

  • Patent number: 6435765
    Abstract: An athletic track having a post-tensioned concrete slab supporting a resilient surface. The athletic track has opposed, parallel rectangular side areas and opposed semi-circular end areas connecting the side areas. The concrete slab is cast in place without requiring expansion joints between segments. Cables are cast into the slab for providing a tension load in the concrete slab. A first set of cables is tilted away from the perpendicular in a first direction while a second set of cables is parallel to the edges of the rectangular areas such that members of the second set of cables cross members of the first set of cables. A third set of circumferential cables is provided in the semi-circular end areas. A fourth set of cables intersecting the circumferential cables is non-radially disposed. The slab has a relatively flat lower surface. Pour strips situated along a line of symmetry are provided between adjacent quadrants of the end areas.

  • Patent number: 6361245
    Abstract: A method of constructing a temporary vehicle parking lot (10) on a land area (12) comprises the steps of: providing a composite drainage material (20) through which water drains; and covering the land area (12) with the composite drainage material (20) so that the land area is underneath the composite drainage material. The composite drainage material (20) comprises a polymeric open mesh core (22) between first and second layers (24 and 26) of a non-woven geo-textile fabric. One (24) of the first and second layers contacts the land area (12). The other (26) of the first and second layers faces away from the land area (12) and provides a surface (50) on which vehicles may be parked. The composite drainage material (20) directs water which contacts the other layer (26) through the first and second layers (24 and 26), through the polymeric core (22) between the layers, and into the land area (12) covered by the composite drainage material (20).
