Concrete Pavement Progress www.acpa.org 6 C O V E R A $137 MILLION REHABILITATION of I-85 between Henderson, N.C., and the Virginia state line has greatly improved the ride for this heavily trafficked, 21.6-mile highway section. The recently placed unbonded concrete pavement overlay has an expected design life of 30-plus years and is designed to meet the needs associated with higher traffic counts, includ- ing an increasingly high volume of truck traffic. Originally paved in 1960, the 55-year-old roadway under- went a rehabilitation project in 2007 that focused on spall repair, slab replacement with asphalt, polymer patching of cracks and an overlay that kept traffic moving, albeit on a less than ideal pavement. “The original pavement exceeded its expected life, but we were seeing slab failures, and we also needed to bring the entire corridor up to current design standards and create a pavement that can handle increasing truck traffic,” says A C C E L E R A T E D O V E R L A Y P R O J E C T M E E T S
