<p>The system has multiple concrete track segments creating a closed track made up of multiple lanes, where the track segments are characterized by a U-shaped cross profile. Each track segment includes a floor section (10) comprising continuous and interconnected channels (13a, 13b), and two vertical wall sections (20, 30), where the floor section and the two wall sections are connected together. A supporting surface includes longitudinal slots (14a-14c), which mate with a set of corresponding slots for connecting the job segments together.</p> |
