Full Depth Reclamation (FDR) is a pavement rehabilitation process that involves grinding, pulverizing, and mixing the existing pavement material with part of the underlying base gravel to create a uniform base material. The material is then graded and compacted to form the final base layer. In some cases, a stabilizing agent such as calcium chloride or asphalt emulsion are added in a second pass to create a more bound and stronger base. The FDR process provides an opportunity to correct road profile issues and break the crack pattern, while using existing materials to create a stronger uniform base layer.
In-place recycled asphalt pavement mixed with a portion of the underlying materials to form a homogenous base layer. In some cases, a stabilizing agent such as calcium chloride or asphalt emulsion is added to produce a more bound or durable base material.
Full Depth Reclamation is typically used on roads that have moderate to severe pavement distress and underlying base issues.
In order to assure the existing pavement and base materials are suitable for the FDR process, it is recommended that sampling and testing of the road is performed in advance of the project. This is especially important when stabilization will be used as it allows for a job mix formula and recommended application rate to be determined.
