  1. City of Auburn Hills Road Asset Management Program February 21, 2014 SEMCOG University

  2. BACKGROUND • Auburn Hills Road Network • Approx. 180 lane miles of roadway • 128 lane miles of asphalt or sealcoat • 50 lane mile of concrete • 2 lane miles of gravel • Began road maintenance program in 1996 • Annually prepare a rolling 5-year road maintenance plan • Combination of asphalt & concrete rehabilitation • Heavy rehab/recon when necessary – leverage funding • Annual investment of $750k to $3.5M • Complete some maintenance “in-house” • PASER road ratings done every 3 years • Continually evaluate & update plan to adjust as needed

  3. DETERIORATION CURVE

  4. $2.65/syd/year over life of pavement – 36 years • Average condition rating = 7

  5. $3.30/syd/year over life of pavement – 36 years • Average condition rating = 6

  6. Road Asset Management Plan • Review and/or Collect PASER data (3 year cycle) • Update RoadSoft Database • Review performance of recent maintenance work • Coordinate with other AMP’s (water, sewer, etc.) • Confirm road selection priorities & adjust as needed • Select maintenance techniques for target roads • Determine costs for selected maintenance fixes • Refine plan based on budget considerations • Prepare yearly plan worksheets, maps, etc. • Finalize report and recommendations

  7. Road Asset Management Plan

  8. CHIP SEAL

  9. CHIP SEAL CONSIDERATIONS • Seals pavement surface • Improves surface friction • Loose aggregate chips & dust after application • “Rough” surface may not be desirable in certain locations • Aesthetics – color is same as aggregate chips • 2nd course can be applied for added structure – “double chip” • Approx. cost - $2.50/syd

  10. SLURRY SEAL

  11. SLURRY SEAL CONSIDERATIONS • Seals pavement surface • Fills small cracks • Improves surface friction • “Rough” surface may not be desirable in certain locations • Aesthetics – mottled appearance after weathering • Traffic control and set time • Heavy traffic (especially turning) can scuff surface • Approx. cost - $3.00/syd

  12. CAPESEAL

  13. CAPESEAL CONSIDERATIONS • Combination of chip & slurry • Provides additional structure, not as much as HMA overlay • Final surface is “rougher” than traditional HMA, may not be desirable in certain locations • Aesthetics – mottled appearance after weathering • Traffic control and set time • Can apply “double chip” to increase structure & fill areas • Performs well to seal cracks and provide “new” road surface • Approx. cost - $5.50/syd

  14. MICROSURFACING

  15. MICROSURFACING CONSIDERATIONS • Seals pavement surface • Improves surface friction • Fills small cracks • No aesthetic issues – looks like HMA • Not good for hand work – best on mainline • Quick set time reduces traffic control • Need to do a large quantity to be cost effective • Approx. cost - $4.00-$7.00/syd

  16. THIN HMA OVERLAY

  17. THIN OVERLAY CONSIDERATIONS • ¾” to 1 ½” HMA overlay • Provides additional structure • Existing pavement can be milled or left as is • Provides smooth new pavement surface • Reflective cracking is an issue • Surface preparation (crack seal/repairs) critical • Approx. cost - $6.00-$7.00/syd

  18. CONCRETE PATCHING/JOINT REPAIR

  19. CONC PATCHING CONSIDERATIONS • Address deteriorated joints • Address cracked, broken, vaulted slabs • Improves ride quality • Underlying base issues can & need to be addressed • 30” joint repairs – transverse & longitudinal • Can do full depth or partial depth repairs • Smaller repair areas cost more/syd than larger areas • Significant traffic control for removal, placement, & cure • Approx. cost - $60.00/syd of repair area

  20. CRACK/SEAT & OVERLAY

  21. CRACK/SEAT/OVERLAY CONSIDERATIONS • Existing concrete is fractured in preparation for HMA overlay • Provides new pavement surface • Can do base repairs to address underlying issues • Joint/crack prep needed before overlay • Should be used when concrete is deteriorated beyond where patching is cost-effective • Reflective cracking can be an issue • Can do “edge milling” – otherwise raises pavement grade • Can maintain traffic throughout construction • Approx. cost - $35.00/syd for 3” overlay

  22. CONCRETE OVERLAY

  23. CONCRETE OVERLAY CONSIDERATIONS • New 4” to 6” concrete surface placed over existing pavement • Provides new pavement surface • Can do base repairs to address underlying issues • Joint/crack prep done before overlay • HMA or geosynthetic “bond breaker” • Roadway grade is raised, impacts to driveways, side streets, sidewalks, drainage structures, etc. • Significant traffic control needed • Approx. cost - $50.00/syd for 4.5” overlay

  24. “In-House” Maintenance • Utilize DPW crews for maintenance activities • Overband Crack Seal • HMA Patching • Saves costs on design, bidding, contract administration • Complete prep work the year ahead of contractor planned work • Saves costs on subcontracting • Improved responsiveness to address complaints • Training

  25. Contracted Road Programs • Annual Asphalt Maintenance Project • Annual Concrete Maintenance Project • Road Reconstruction Projects • Funded projects let through MDOT • Maintenance projects are done “Log” style

  26. Asset Management Education • Public Education • Information Meetings • Educate/Inform Elected Officials • Public Notices Prior to Construction • Updates During Construction • Feedback on Performance After Completion

  27. Asset Management Education

  28. Asset Management Education

  29. Asset Management Education

  30. Lessons Learned • Match the right maintenance treatment to the right roadway. There is no “Silver Bullet” • Determine if there are underlying base issues before using surface treatments. Don’t put lipstick on a pig. • Don’t be afraid to try new things. It’s good to have a lot of tools in the toolbox. • “In-house” maintenance can be combined with contract work to reduce costs. • Education with elected officials & the public is essential to a successful asset management program.

  31. Lessons Learned • Know where the elected officials live. That way you can understand the complaints & help with PR. • Consider the uses of the roadway and aesthetic desires of the area when selecting maintenance treatments. • Leverage funding opportunities whenever possible, but continue to invest in the road network. • Coordinate roadway asset management plan with other utilities as much as possible. • Continually monitor the roadways, including those that were just maintained to track performance.
