The AASHTO TAM Portal is a transportation asset management knowledge portal: a searchable database of links to a wide range of resources related to transportation asset management. The interactive portal is designed to provide transportation asset management practitioners with the ability to search and access relevant documents and/or web links to information from multiple sources. The report documents the results of the activities carried out under the continuation of NCHRP Project 08-36(125).

This Report, from NCHRP 08-36/Task 118, is on Performance Measures for State Infrastructure Preservation. It provides a roadmap with some guidance on the highest priorities for agencies to successfully apply performance-based preservation programming. The roadmap is broken into three tiers. Every transportation agency has a different level of maturity in data collection and analysis, asset management, performance management, target setting, and other activities which support performance-based preservation programming. The tiers are intended to provide guidance to those agencies with limited maturity, those with moderate maturity, and those with significant maturity in performance-based preservation programming.

The objectives of this research for NCHRP 02-25 are the following:
1. To produce a roadmap of effective human capital strategies for state DOTs, identifying critical areas necessary in the future to attract, retain, and develop a sustainable, qualified transportation design, construction, and maintenance workforce;
2. To identify trends, policies, and processes critical for developing and maintaining an adaptive organizational framework that will attract, retain, and develop a qualified workforce beyond 2030; and
3. To prepare an evidence-based guide that transportation industry organizations may use when developing and establishing an effective human capital program for a qualified workforce into 2030 and beyond.
The scope will be limited to the transportation workforce in design, construction, and maintenance.
