A county gave site tours on one of the largest concrete pavement preservation (CPP) projects to ever have been undertaken at an October 3 open house in Highlands Ranch, Colorado.
The PCA Rocky Mountain Region, Colorado/Wyoming Chapter of the American Concrete Pavement Association and the International Grinding & Grooving Association (IGGA) co-hosted the event.

The Highlands Ranch metropolitan area – under the administration of the Douglas County Department of Public Works Engineering in Colorado – had stretches of roadway with aging pavement ranging from 25 to 30 years old that were nearing the end of their design life.
