"Dealing with the New Normal" - Making the Most of Reduced Resurfacing Budgets

  1. 1. “Dealing with the New Normal” Making the Most of Reduced Resurfacing Budgets Panel Members Don Jacobovitz – Putnam County Public Works DirectorGeorge Recktenwald – Volusia County Public Works Director Ken Holton – City of Tampa Public Works Director Warren Bryant – City of Lakeland Public Works Manager David Morgan – Orange County Paving Coordinator Bob Siffert (Moderator) – Asphalt Paving Systems
  2. 2. Does This Look Diversified? Current County Pavement Management Hot Mix Overlay Mill & Overlay Micro-Surfacing CIR/FDR Chip Seal Rejuevenator Crack Seal
  3. 3. This is Diversification… Pavement Management Urban/Rural County Hot Mix Overlay 5% 10% 20% Mill & Overlay10% Micro-Surfacing CIR/FDR 20% Chip Seal 15% Rejuevenator 20% Crack Seal
  4. 4. Effective Pavement Management“Right Road, Right Treatment, Right Time” 100 Rejuvenation Crack Seal 80 Chip Seal Micro-Surfacing 60PCI Cape Seal 40 Asphalt Overlay Cold In-Place Recycling 20 Full Depth Reclamation 0 Years
  5. 5. Value of Diversification
  6. 6. Crack Sealing
  7. 7. Crack Seal Process Description 1. Clean debris & organics out of cracks 2. Extrude sealant material into cracks 3. Dust with cement dust to accelerate set time
  8. 8. Crack Seal Benefits1. Retard Reflective Cracking2. Prevent Moisture Intrusion to Base
  9. 9. Crack Seal Discussion…
  10. 10. Micro-Surfacing
  11. 11. Micro-Surfacing Process Description1. Granite aggregate & asphalt emulsion are combined onsite. 2. The slurry is applied to the existing asphalt in one or two lifts.
  12. 12. Micro Surfacing Benefits 50% – 70% less $ than conventional asphalt overlay or mill & overlay.Maintains existingroadways at a higherlevel of service.
  13. 13. Micro Surfacing Discussion…
  14. 14. Chip Seal / Surface Treatment
  15. 15. Chip Seal TypesSingle Chip SealDouble Chip SealCape Seal
  16. 16. Chip Seal Process Description1. Apply a thick layer of asphalt emulsion 2. Apply a layer of granite aggregate
  17. 17. Chip Seal Benefits Chip Sealing is the most cost effective resurfacing technique available.When topped with fogseal, Chip Seal takeson the appearanceopen grade asphalt.
  18. 18. Chip Seal Discussion…
  19. 19. Cold In-Place Recycling
  20. 20. Cold In-Place Recycling Process Description1. Inject asphalt emulsion stabilizing agent while milling the existing asphalt.2. Conveyor recycled material into a modified asphalt paver.3. Lay the recycled material down at the appropriate cross-slope and elevation.4. Pave over the recycled base course with conventional asphalt.
  21. 21. Cold In-Place Recycling BenefitsMuch less $ than remove/replace. Removes entire cracking network.Minimizes disruption to public. Adds significant structural integrity.Reuses existing materials. Saves taxpayer dollars.
  22. 22. Cold In-Place Recycling Discussion…
  23. 23. Full Depth Reclamation
  24. 24. Full Depth Reclamation Process Description 1. Reclaim the asphalt and the existing base material and add appropriate stabilizing agent. 2. Grade & shape stabilized base material to the proper grades and elevations. 3. Compact the reclaimed base material to achieve density. 4. Prime and pave the finished base with asphalt.
  25. 25. Full Depth Reclamation BenefitsHalf the cost of remove & replace. Removes entire cracking network.Simplifies road widening projects. Adds significant structural integrity.Reuses existing materials. Saves taxpayer dollars.
  26. 26. Full Depth Reclamation Discussion…
  27. 27. Paying the Right Price… VSPiggybacking Competitive Bidding
  28. 28. Procurement Methods…A. Piggybacking i. Get Multiple Piggyback Quotes – PROMOTE COMPETITION ii. Make Sure All Items Being Piggybacked Were Competitively Bid • Review the Original Bid Tabulation That Includes ALL Bidders iii. Review Original Specifications iv. Evaluate Your Agencies Piggyback Policy v. Make Sure the Piggyback Contract is Recent and LargerA. Competitively Bidding i. Use Good Specifications ii. Hold the Contractor to the Specifications iii. Encourage Contractor Involvement at Pre-Bid to Reduce the Possibility of a Protest
