paving, according to the agency. One reason: all of metro Houston's main lanes are CRCP. The Texas Concrete Pavement Association is working with the Texas A&M Transportation Institute to docu- ment CRCP performance and cost data. One goal of the research is to encourage engineers to factor pavement resiliency into their decisions. "This resiliency topic can be tailored to whatever the most immediate threat is in your geographic area," Luk- fahr says. Owners may start recognizing resiliency to extreme weather as a decision factor, perhaps leading to more CRCP in evacuation routes, she adds. Several states incorporating CRCP Even though CRCP tests in 1949 and 1971 were suc- cessful, California stuck with jointed plain concrete pavement (JPCP). But CRCP's minimal repair and reha- bilitation advantages have led California to return to it in the past decade, and other states are following suit. The Federal Highway Administration is working with several states to advance CRCP use, says Sam Tyson, FHWA concrete pavement engineer. "A significant new project on NM 136 will carry high volumes of heavily loaded truck traffic from an inter- national border-crossing from Mexico to a rail facil- ity north of the border in New Mexico," Tyson says. The year-long project began last October, with CRCP construction slated for Spring 2018.

The continuously reinforced concrete pavement on the TxDOT freeway system remained intact in the downtown Houston area. Source: TxDOT
