Florida Department of Transportation — SR 37 Full Depth Reclamation

SR 37 is a rural road in the first district of the Florida Department of Transportation (FDOT), known for carrying heavy truck traffic volumes. When cracking began to form along the road, FDOT knew that they had to find a solution that would address the issue with minimal impact on the environment. The solution: a $6.6 million full-depth reclamation, also known as a FDR. The FDR process consists of mixing and pulverizing the existing asphalt surface, mixing it with the underlying base or sub-base materials, and then adding in stabilizing agents. It provides a way to reclaim and recycle the existing roadway materials, transforming them into a new base and removing the cracking. Not only did this project serve as a cost-effective way to solve the issue, it was completed in just 34 days – allowing traffic to resume quickly with minimal impact to drivers.
