Abstract

Systems and methods for providing a running track having a reinforced base using post-tensioning are provided herein. In one exemplary configuration, the track comprises a reinforced concrete slab base that is poured over and around post-tensioning cables suspended therein. The post-tensioning cables include transverse cables that extend transversely across the base, and lengthwise cable structures extending lengthwise through the base. Each lengthwise cable structure includes a series of individual segments that are joined end-to-end to form respective continuous loops and are individually tensioned. The lengthwise cable structures thus exert compressive forces on the base that are continuous and uninterrupted about the circumferential length of the track. Moreover, the lengthwise cable segments are joined/tensioned from within voids initially formed within the concrete base and, after tensioning, these voids are filled with concrete to provide a concrete base having a uniform top surface that can also be covered in a running surface.
