Outline of Discussion:

1. Briefing on the Existing Roadmap

a. Motivations for Development

b. Development Process

c. Results

2. Discussion of Research & Tracking

3. Discussion of Roadmap Update Needs


Transportation System Preservation Research, Development, and

Implementation Roadmap


Motivations for the Roadmap

Preservation research identified as a need during program appraisals

Individual projects have been sought in the past

No coordinated approach to address preservation research needs

Other Roadmaps: HMA, PCC, now PMS

Bottom Lines:

Lots of Research Activities in Preservation!

Most are Initiated to fulfill specific client needs.

The Roadmap is a Planned Set of Research Ideas to Fulfill the Overall Agency and Industry Needs, and Advance Preservation as a Whole.

Discussion Questions:1. What research do we need to track?2. Who will do the tracking, and HOW?






c. Results

2. Discussion of Research & Tracking

3. Discussion of Roadmap Update Needs


Do We Need to Update the Preservation Roadmap?

Has there been a change in focus within the preservation community that is different than the climate in which the Roadmap was developed? Energy Use / GHG Emissions / Sustainability?

Budget Constraints Driving Preservation Decisions More?

Increasing Focus on Performance Measures?

Sufficient Progress in Tackling Problem Statements to Warrant a Review and Update Process?

HMA Roadmap is revisited by FHWA and NAPA every couple of years:

Goal: “Keep the Preservation Roadmap a Living Document” ???


Preservation and Asset Managementwon’t bring short-term glory,

but they will bring long-term satisfaction!
