6 /The Road Ahead WWW.CO-ASPHALT.COM Project Completed in Record 10 Day Round the Clock Construction Durango – La Plata County Airport Runway Rehabilitation During a 10-day complete shutdown of the Durango - La Plata County Airport (DRO) in Durango, Colorado, Four Corners Materials teamed with sister CRH companies, United Companies and APC Southern, to complete a $12.7 Million re-surfacing project of the runway and adjacent taxi connectors. From midnight on the 6th of September to midnight of September 16th , approximately 150 people comprised of CRH Oldcastle SW Group employees, electrical, striping, survey, milling, and trucking sub-contractors, worked 24 hours a day to complete a 3” mill and re-surface of a 150- foot wide by 9200-foot- long runway and 7 taxi connectors, including crack filling, electrical work and temporary striping. Durango-La Plata County Airport typically sees a steady flow of airplanes coming and going during daytime operations, including private planes and commercial jets. But as of late, all the activity has stayed on the ground, where a small army of road crews worked around the clock to repave the 1.75-mile runway. On Thursday September 7, an asphalt milling machine moved slowly along the length of the runway, which is 150-feet wide, removing old asphalt while about 40 trucks hauled it away.
