Athletic track with post-tensioned concrete slab

机译:带有后张混凝土板的田径跑道

摘要

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.
