March 2018 | EquipmentWorld.com 52 it kept getting hit by trucks. From highways to airports, owners are weighing the higher initial cost of CRCP against long-term advantages, including fewer repairs and maintenance and more rehabilitation options. Lukefahr says the resiliency of CRCP can be critical, not just in flooded areas, but also for roads with heavy truck traf- fic. And in areas with wildfires, it will fare much better than asphalt, she says. "Those TxDOT CRCP sections in downtown Houston have performed better under those extreme weather events than most people would have otherwise predicted," says Lukefahr, a former concrete and concrete pavement engineer with the Texas Department of Transportation. Texas DOT officials confirm that re- pairs weren't needed for CRCP. "We are not aware of any issues with the CRC pavement occurring after waters receded following Hurricane Harvey," says Danny Perez, public information officer for Texas DOT. "It is the joint area where many distresses occur in concrete pavement," Perez explains. "This could certainly be one of the reasons why CRCP outper- forms jointed concrete pavement." There's no comparative data between flooded CRCP sections of Texas DOT pavements and other jointed and flexible road technology | continued Mike Plei, an expert on continuously reinforced concrete pavements, pic- tured on a CRCP jobsite in Cook County, Georgia, in 2010.

Engineers and project managers from Florida DOT and Alabama DOT checked out the construction dur- ing an open house held by Commercial Metals, also on the project. Florida built its first CRCP project two years later at a rest area parking lot off Interstate 75. Source: Commercial Metals Co.
