Target Completion Date: October 30, 2021 Pavements
Traditional maintenance activities employed by the Virginia Department of Transportation are becoming increasingly costly in that they often do not last as long as intended. Full depth reclamation (FDR) along with application of thinner surface treatments such as chip seals, cape seals, micro-surfacings, and 1-inch asphalt concrete courses, cover more area for less money and can be placed more rapidly. FDR can be used to fix the underlying issues in an existing pavement and, combined with thin surfacing, provide significant savings.
An example of this advanced practice is proposed for a 3-mile long project (2 lanes) on Route 602 in Surry County. The work is proposed to include FDR with a triple chip seal, modified prime and double seal surface treatment, and 1” asphalt concrete overlay. This project will document the construction and performance of this section. A return on investment analysis will also be performed.
