Publication number: 20030165357Abstract: 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.Type: ApplicationFiled: September 3, 2002Publication date: September 4, 2003Inventors: Rainer Hart, Darco Kunsic

Patent number: 6435765Abstract: 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.Type: GrantFiled: July 10, 2000Date of Patent: August 20, 2002Inventors: Brad L. Crane, Robin Melton
