摘要：	Thirty-year-old rock reinforcements at the Barron Mountain rock cut along I-93 near Woodstock, NH are the subject of condition assessment and estimation of remaining service-life. The New Hampshire Department of Transportation (NHDOT) and McMahon & Mann Consulting Engineers, P.C. (MMCE) performed the condition assessment in two phases. Phase I of the condition assessment was completed in the fall of 2003 and included an evaluation of site conditions, review of installation details, estimation of remaining service life and condition assessment using nondestructive testing. MMCE submitted an interim report to NHDOT in February 2004 describing results from Phase I and recommendations for Phase II. The second phase of the project (Phase II) consists of invasive testing of selected reinforcements to verify results from Phase I. Phase II was conducted in the fall of 2004 as a pooled fund study (TPF-5(096)) with participation from the New Hampshire (lead agency), New York and Connecticut Departments of Transportation and the Federal Highway Administration. This report presents (1) a summary of results from Phase I followed by (2) a detailed description of the approach used to conduct Phase II; (3) results from Phase II; (4) comparison of observations and results from NDT conducted in Phase I and invasive testing in Phase II; (5) Conclusions; and (6) Recommendations.
