An NCHRP research project that studied the condition and maintenance methodology of culverts in order to produce a handbook, which provides guidance on efficient planning and rehabilitation techniques.

An NCHRP research project conducted from 2014 to 2016 to analyze current risk management practices in State DOTs, and to produce a guidebook of risk management strategies, processes, and tools.

This NCHRP research project, conducted between 2007 and 2009, explores a process by which state DOTs can make decisions regarding fleet management. The research highlights the outsourcing and privatization of maintenance, and culminated in the creation of NCHRP Report 692, produced under project 13-03A. To view the report, click here.

The goals of this project are to produce a report of 2004-2008 Virginia Work-Zone Crash Facts as a stand-alone document and to develop a more robust set of work-zone safety performance measures for Virginia. The researchers will consider both program-level and project-level measures. All roads that VDOT administers will be included for the program-level measures. However, for the project-level measures, the scope is limited to interstate highways because of data availability.

This report is the final report in a series of five examining the complementary effect risk management has on asset management. This report focuses on physical, seismic, climactic, and threats of other types can be managed. The focus of this report, as opposed to the previous four, if the focus on just the negative effects of uncertainty, as opposed to looking at both the positive and negative effects. Such risks are normally external and difficult to know precisely when they will occur, although their occurrence is inevitable over the long term, like an earthquake or a major blizzard.

The final report in the Asset Management Financial Report Series covers asset valuation and depreciation for TAM. Asset value is commonly used in the UK and Australia to capture and convey meaning from asset condition and age. It demonstrates the benefit an asset brings to society, while depreciation acknowledges the costs. Through this report, asset value is explained and its potential uses are displayed; examples are provided from states with exemplary practices and other potential uses are offered.

This report examines how a number of state DOTs have used Geographic Information Systems (GIS) applications to fulfill MAP-21 requirements as part of their TPM programs and efforts, and was developed in response to the requests of participants at an FHWA-sponsored peer exchange on the same topic, held June 30-July 2, 2015 in Spokane, WA. Researchers from the Federal Highway Administration and the Volpe Center studied how state DOTs in South Carolina, Ohio, Vermont, and Maryland used GIS tools in their organizations, and presented a number of findings across departments. The report supports geographic information system (GIS) practitioners and decision-makers by identifying examples of noteworthy practices, considering the advantages and disadvantages of different approaches in using GIS solutions for TPM and related efforts, and determining how to best use GIS to communicate the impacts of performance-based operations and planning at the State DOT level.

From FHWA's May 2012 Edition of Focus, this article outlines the purpose of the Transportation Asset Management Expert Task Group (TAM ETG), and additionally provides information on the ETG's current and future initiatives.

This report provides an overview and the updated results of the Oversize / Overweight Permits Process Improvement Project. The project results have been continuously updated and includes a new, state-of-the-art permitting system that provides self-issued permits for some customers.

This Guidance is aimed at local highway authorities and provides advice on how asset management principles may be used to support a more efficient approach to maintaining highway infrastructure assets. It includes 14 recommendations which should be considered in their entirety as the minimum requirements to achieve an appropriate level of benefit from asset management. The Guidance was drafted by a team from Atkins on behalf of the Highways Maintenance Efficiency Programme (HMEP) and is endorsed by the UK Roads Liaison Group.

The research developed a database system for pavement maintenance records within a highway agency.

This project explores the importance of preventive maintenance at airports, and produced a guidebook which presents preventive maintenance methodologies and implementation strategies.
