  5. 5. “Times are changing. It’s no longer constructing roads, it’s about preserving and maintaining the roads. It’s about doing pavement treatments at the right time so we effectively extend the service life and improve the quality of service for the traveling public.” Jim Sorenson Sr. Construction and Preservation Engineer
  6. 6. Typical County – Physical Assets  Government Buildings  Parks  Equipment Fleet  County Garages  Culverts and Bridges  Highways
  7. 7. Value of Assets Cost to construct Cost to replace Loss of Use Inconvenience to Public
  8. 8. Preservation of Assets Assets deteriorate over time Deterioration rate can be reduced with preventive maintenance techniques Pay me now or pay me later
  9. 9. Asset Management Pavement Management Plan  Let deteriorate and replace Worst first  Preservation approach Preventive Maintenance
  10. 10. Typical County’s Highways as Assets Say Typical County - 400 lane miles of pavement Deteriorate over time  Oxidize, crack, pothole Cost to rehabilitate  $400 million (@ $1M/lane mile) Cost to construct  $600 million (@ $1.5M/lane mile)

  29. 29. Paving CycleGoal Paving Cycle = Average Treatment LifeCompute number of years to treat all roads Divide total miles by miles treated Example: 6000 total miles 600 miles surface treated (omit crack sealing) 6000 miles / 600 miles = 10 years

  32. 32. Benefits of Pavement PreservationLower annualized costBetter overall network conditionReduced vehicle damage and construction delayTraveling public better served
  33. 33. Remaining Service Life Assume  Every mile of agency’s highway network is rated by number of years remaining until the end of its life – terminal condition  Not necessarily a failed road  But, a pavement condition set by management

  44. 44. SURFACE TREATMENTS ADVANTAGES • Very economical • Preventive maintenance treatment that adds 5 to 8 years life to a Pavement • Seals and renews old pavement Surface • Prevents water and air intrusion into pavement • Improves skid resistance
  45. 45. FIBERMAT® ADVANTAGES  To bridge alligator cracking and delay reflective cracking  To improve skid resistance  To protect and waterproof sub- base  To improve tensile strength  To add a flexible interlayer to absorb movements  Retards reoccurrence of wheel rutting when used in conjunction with other asphalt layers
  46. 46. MICRO SURFACING & SLURRY SEAL ADVANTAGES  Cuts labor costs  No change in curb reveal  Improves pavement durability, extends life  Superior Adhesion to existing pavement  Fills ruts and cracks  More flexible at low temperatures, stable at high temperatures  Sets to a hard, black finish  Provides excellent traction and skid resistance  Conforms to all government regulations
  47. 47. PAVER PLACED SURFACE TREATMENT Ultra-thin Hot Mix Overlay ADVANTAGES  Fast application  Ultrathin wearing course  Conserves high quality aggregates  Low surface noise  Reduces “misting” on wet pavements  Macro-texture yields high skid resistance  Corrects road profile  Tacks and seals surface prior to overlay  No curing time required  Suitable for all traffic volumes  Minimal traffic disruption during placement  Suitable overlay for asphalt and concrete pavements  Requires only short single lane traffic closure  Service life up to 10 years  Economical
  48. 48. COLD IN PLACE RECYCLING ADVANTAGES  Conserve Aggregate, Asphalt & Energy  Reduce surfacing costs  Reduce reflective cracking  Restore cross slope and crown  Cost effective  Minor inconvenience to traffic  Service life up to 15 years  No hauling materials except for additive under normal conditions  Average two to three lane miles per day  10 year evaluation, endorsed by the Connecticut DOT as cost effective  Ontario Ministry of Transportation - more environmentally friendly then traditional paving methodsNominated for the 2007 Summit Award for Leadership in Green Procurement
  49. 49. Summary FHWA Endorses Pavement Preservation Highways as Assets Pavement Preservation vs Worst First  Keeping Good Roads Good  Right Treatment, Right Road, Right Time NYSDOT Pavement Preservation Paving Cycle Remaining Service Life
  50. 50. Learning Assessment Questions The FHWA endorses the Worst First pavement maintenance strategy. An agency should have a Management Plan for each class of assets that they are responsible for. The NYSDOT Pavement Scoring System is a 1 to 10 point scoring system. Pavement Preservation Treatments a. Seal cracks to keep water out b. Rejuvenate a weathered surface c. Prolong the life of a pavement d. All of the above The window of opportunity for applying Pavement Preservation treatments is wide.• Over the past several years, the Pavement Condition Ratings for NYSDOT roads has been related to the funding level for Pavement Preservation.• The Remaining Service Life concept is easy to understand, but difficult to operationalize.• Surface Treatments (Chip Seals) cannot improve pavement friction characteristics.• The surface texture of Paver Placed Surface Treatment is indistinguishable from dens graded hot mix asphalt.• Cold in Place Recycling of asphalt concrete pavements is environmentally friendly.
