TRB's National Cooperative Highway Research Program (NCHRP) Research Report 866: Return on Investment in Transportation Asset Management Systems and Practices explores how transportation agencies manage their transportation assets, and provides guidance for evaluating the return on investment for adopting or expanding transportation asset management systems in an agency. As the term is most generally used, transportation asset management (TAM) entails the activities a transportation agency undertakes to ...

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores NCHRP Synthesis 510 : Resource Allocation of Available Funding to Programs of Work. NCHRP Synthesis 510 addresses complex decisions regarding fund allocation among competing priorities.The report includes a literature review, survey, and case studies to determine the state of the practice for resource allocation among state departments of transportation.

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores TRB's Highway Capacity Manual and NCHRP Report 825 : Planning and Preliminary Engineering Applications Guide to the Highway Capacity Manual. The sixth edition of the HCM incorporates the latest research on analyzing the capacity of highways and streets, ensuring that the manual will continue to be a go-to resource for transportation agencies nationwide. Its companion, NCHRP Report 825, addresses applications ...

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores NCHRP Report 826 : Estimating Highway Preconstruction Services Costs, which explores ways to implement a framework for data-driven cost-estimating models for transportation projects. This framework helps agencies to estimate how much it will cost to plan, program, permit, and design a project during the early phases of project development.

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores NCHRP Report 831 : Civil Integrated Management (CIM) for Departments of Transportation, which provides an overview of benefits to agencies that use digital data tools, such as GPS and lidar, and applications, such as 3-D modeling of complex construction strategies and asset management.

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores NCHRP Report 840 , which provides a toolbox and guidance that helps transportation agencies compare and select stormwater best management practices. Agencies can customize the tool to their environmental priorities and local conditions. The Toolbox also provides scientific support for a watershed-based approach that agencies can use as they work with regulators to make stormwater management decisions.

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores how NCHRP Report 819 : Self-Consolidating Concrete for Cast-in-Place Bridge Components developed guidelines for using self-consolidating concrete (SCC) in cast-in-place bridge components and proposed changes to the American Association of State Highway and Transportation Officials' (AASHTO's) specifications to encourage appropriate use of the material by state transportation departments. Many states only perm...

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores new technologies and practices to inspect culvert and storm drains. The manual assists transportation agencies with incorporating culverts into modern asset management systems—a move that allows agencies to improve the way they prioritize rehabilitation activities and more clearly demonstrate the need for repair funding. The manual provides guidance to help agencies reduce costs and improve safety by addressi...

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results summarizes nondestructive evaluation (NDE) methods for assessing the condition of in-service post-tensioning and stay cable systems. Post-tensioned (PT) girder bridges and stay cable bridges pose a challenge to bridge inspectors because steel tendons used as the primary structural support in these bridges are typically embedded in massive concrete (internal tendons) or opaque ducts (external tendons or stay cables) an...

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores guidelines to prevent failures in small-movement expansion joints (SMEJs) on bridges. SMEJs enable a bridge to accommodate movements caused by temperature changes and rotation, while also directing water and deicing chemicals off the deck and away from the bridge. This summary explores research aimed at developing SMEJ maintenance, repair, and replacement guidelines to mitigate bridge corrosion or embankment ...
