The six-lane, 400 meter track was installed in 1998 and refurbished in 2001, 2005 and 2011. As the surface wears, much like the sole of a shoe, granules and latex are added. Dunleavy said that as additional layers were added the permeability of the surface diminished. As a result, instead of evaporating, water remained trapped between running surface and the asphalt base. With warm temperatures, the water turns to vapor and, unable to escape, causes the surface of the track to bubble.
