Thank you to the Highlands Ranch Metropolitan District, Douglas County, and Multiple Concrete Enterprises for helping us put together an informative and hands on open house showcasing concrete pavement preservation and an up close view of the diamond grinding process! Thanks also to the Douglas County Sheriff’s Department for keeping us safe during our site visit.
In 2016 Douglas County, Colorado will finish repairing and grinding 120 lane miles of concrete pavement in Highlands Ranch. These 7.5-inch thick 25 to 30-year old concrete pavement roads were designed to last 20 years on the existing expansive clay subgrade, and they have far exceeded the design traffic they were expected to carry. Smoothness is being restored on these durable old concrete pavement roads to improve ride and extend their life even further.
Larry Scofield with the International Grooving and Grinding Association (IGGA) discussed concrete pavement preservation, the basics of diamond grinding equipment and processes, and presented what we know about concrete pavement blow ups.
