An athletic track multi-layer paving section and associated concrete footing edge condition comprise a rubberized track surfacing layer over athletic track asphalt paving, supported by a crushed surfacing top course over a subgrade compacted to ninety-five percent dry density. A vertical boundary element is embedded in a cast-in-place concrete footing with a specific diameter and depth, surrounded by crushed surfacing and subgrade materials. Dimensions indicate layer thicknesses of three inches for the asphalt paving and six inches for the crushed surfacing course, with footing dimensions specified per plans.
