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? AASHTO Subcommittee on Maintenance - PTWG July 18, 2011
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 AASHTO Subcommittee on Maintenance - PTWG July 18, 2011
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” ? ? ? AASHTO Subcommittee on Maintenance - PTWG July 18, 2011
Preservation and Asset Management won’t bring short-term glory, but they will bring long-term satisfaction! AASHTO Subcommittee on Maintenance - PTWG July 18, 2011
