Project Details

Project Description: 

The Virginia Department of Transportation (VDOT) is currently undergoing construction of the Hot Lanes project, and as part of the realignment between Interstates 495N and 66W, an existing mechanically stabilized earth (MSE) retaining wall bridge ramp was demolished in July 2012. The MSE wall, built with galvanized steel bar mat reinforcement connected to a concrete panel facing, was constructed in 1976. The age of the wall makes this a good candidate for assessment and drawing conclusions to similar walls in similar environments.

Goals 

The main objective of this forensic examination is to investigate the condition of steel bar mat reinforcements as a function of wall location and backfill quality for a mechanically stabilized earth (MSE) wall bridge ramp.
