Metro Nashville Public Works hired RoadWorx, Inc. to fix Couchville Pike, a heavily-traveled 1.6-mile stretch of road that contained 15% failure.
Using full depth reclamation, we reclaimed the existing pavement and base to a depth of 8 inches using 38 pounds of Portland cement per square yard. The reclaimed base was designed to achieve 400 psi unconfined compressive strength in seven days. The job started on Monday and was finished on Friday. “Considering the client’s time constraints, FDR was the only logical option on Couchville Pike,” said RoadWorx Inc. President Barry Wilder. “This road is under a lot of pressure from not only high volume of traffic but over-sized loads too. Bringing in base stone and removing existing pavement would have only prolonged the job and been more expensive.”
