2009 ACEC/ODOT CONFERENCE ODOT’S 1R PROGRAM Liz Hunt, P.E. ODOT Pavement Services Engineer

Issue  With rising material and construction costs and declining funding it is essential that ODOT’s Highway construction and maintenance programs ensure that all available dollars are directed to activities and projects which optimize the Highway System condition as a whole.

1R Technical Bulletin

1R Program Components  Annual bucket for preservation projects requiring only a single lift of paving.  Anticipated savings from developing projects under 1R standards (currently set at $7M/year) would be used to address substandard priority safety features.

1R Projects  Address pavement feature only  Adversely impacted safety features need to be addressed like raising a guardrail to accommodate an overlay.  Safety features addressed through separate program based on priority needs.

1R Standard Approval Process  Region  Pavement Services Unit  FHWA

Pavement Details

Eligible Projects  Single paving lift  Non-structural inlay or overlay (2 to 3”)  Leveling course allowed

Required 1R Items  Replacement of striping and delineation  Gravel shoulders matched to paved surface elevation  Replacement of signal loops if impacted  Replacement of rumble strips  Adjust existing features as needed  Vertical clearance policy followed  Traffic mobility standards followed

Benefits of a 1R Program  Provides opportunity to plan and deliver projects strategically.  Allows more timely development of single lift preservation projects.  Simplifies project delivery – only impacted features are addressed.
