Developing Guidelines for Integrating Safety and Cost-Effectiveness into Resurfacing, Restoration, and Rehabilitation (3R) Projects
The aging U.S. highway system, coupled with fiscal constraints, is placing increased pressures on
highway agencies to maintain the highway system in a cost-effective manner and is, thus,
creating greater needs for 3R projects.
The TRB National Cooperative Highway Research Program's
NCHRP Web-Only Document 244: Developing Guidelines for Integrating Safety and Cost-Effectiveness into Resurfacing,
Restoration, and Rehabilitation (3R) Projects presents the results of research to develop improved design guidelines
for 3R projects. The guidelines were developed to
replace the older guidance presented in
TRB Special Report 214: Designing Safer Roads: Practices for Resurfacing, Restoration, and Rehabilitation.
Supplementary to the Document is
NCHRP Research Report 876: Guidelines for Integrating Safety and Cost-Effectiveness into Resurfacing, Restoration, and Rehabilitation (3R) Projects. Two spreadsheet tools for benefit–cost analysis in support of design decisions for 3R projects also accompany the report.
Spreadsheet Tool 1 is a tool for analysis of a single design alternative or combination of alternatives.
Spreadsheet Tool 2 is a tool for comparison of several design alternatives or combinations of alternatives.
