Colorado Public Works Journal, Spring-Summer 2019

2019 Excellence in Concrete Pavement Awards Allium Street is a limited access vehicle service road on the east side of the airfield, and is critical for airfield maintenance, firefighting, and construction vehicles. The existing asphalt was badly deteriorated, and the area adjacent to Taxiway EC was out of FAA compliance. This project replaced the failed pavement and corrected the transverse grade issues. Roadway materials had to meet CDOT requirements, and safety, environmental and all other aspects of the project fell under FAA regulations. Recycled aggregate was used for the aggregate base course and for the #67 coarse aggregate in the concrete mix. This was produced at DIA’s north recycling yard, eliminating the import of new materials and the associated trucking. The closure of Taxiway EC was restricted to a maximum of 34 days, and construction was complete, and the taxiway reopened in 21 days. The project finished on time, with no accidents.
