Research and Issues in Maintenance and Preservation of Infrastructure Presented to Pooled Fund April 19, 2012 Lisa Loyo Manager, Information Services Transportation Research Board
What are we discussing? • • Infrastructure (pavement and bridges) preservation and maintenance • How do we decide when to preserve or maintain a road or a bridge or build something new? • Not the same as historic preservation • Similar questions and decisions as for equipment management – when do you replace versus repair? • Other definitions or comments ?
Perspective • Consider the entire state – projects often are distributed by region rather than based on ROI • Look at infrastructure as an entire network, and not individual projects • Comments?
If you have received a reference question on this topic, how did you respond?
People and Organizations • Colleagues at other DOTs • Use RIP (rip.trb.org) to locate organizations and people doing similar work • Staff who maintain fleet equipment
