CASE STUDY 3:
describes embankment construction to provide grade separation for an access road and improved land usage at the Front Range Tire Recycling Facility in Sedalia, Colorado. Construction of the road involved an initial excavation into the slope (i.e. a “cut” excavation), to provide a relatively flat surface to support the tire bales. Next, the tire bales were stacked in a “brick-like” fashion using a forklift. Once the stacked bales reached the desired height for the roadway, the bales were compacted using a front-end loader. In addition to soil, tire shreds were spread over the surface of the tire bale layers in an effort to level the roadway. Finally, soil was placed in uniform layers above the final layer of tire bales and compacted.
