Full Depth Reclamation - A recycling method in which all of the asphalt pavement section and a predetermined amount of underlying material are treated to produce a stabilized base course. Heater Planing - A process in which a device heats the pavement surface and a stationary or
Full-depth recycling (FDR) has the potential to provide agencies with tremendous cost and environmental advantages by facilitating the reuse of existing asphalt materials in pavement base layer reconstruction. Specifically, FDR is the process whereby a failed asphalt pavement is
Full depth reclamation (FDR) is the process of pulverizing and blending all layers of an asphalt pavement in-situ, as well as part or all of the underlying base materials to provide a homogenous material upon which to place a surface course. "FDR has been growing in popularity over the past eight to 10 years," said Product Application Specialist Anthony Low at , Peoria, Illinois.
The Benefits of a Full-Depth Pavement Reclamation. There are all sorts of advantages to performing a full-depth reclamation. The primary advantages include decreased parking lot maintenance costs, structural benefits and the fact that this …
Partial-depth patches involve the removal of the damaged pavement, typically by sawing it out, to the appropriate depth; this method does not expose the base. The contractor then installs new asphalt paving in the void. To perform a full-depth patch, the contractor removes the damaged pavement all the way down to the base layers so that he can ...
