Concerns about the deteriorating asphalt and how it would affect the performance of the bond breakmaterial led to a change order to completely remove the asphalt. Once uncovered, it was ap- parent that the original concrete was in surpris- ingly good condition, says Bragg. “We repaired 475 square yards of the existing concrete, which is 4% of the original concrete.” Hercules Way was part of another project that King Asphalt was handling for the county. “This was our first RCC project, but we partnered with Andale Construction to produce the RCC and handle the finish work,” says Loyd Amos, recyclingmarket development manager for King Asphalt. “We have a high density paver and often handle projects that include paver-laid cement modified recycled base at depths that range from 6 to 12 inches, so our crew was accustomed to the increased lift thickness when it came to pav- ing the RCC.” Andale Construction was brought onto the proj- ect to provide themix design, oversee production of the RCC and lay the geotextile fabric because the company has extensive experience with RCC projects, explainsMattMunsick, vice president of Andale Construction. “We workedwith Carolina HERCULES WAY, SC “Hercules Way’s original concrete pavement was overlaid with 1 ½ inches of asphalt that had completely oxidized.
