- 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. Crack Seal Benefits 1. Retard Reflective Cracking 2. Prevent Moisture Intrusion to Base
- 10. Micro-Surfacing
- 11. Micro-Surfacing Process Description 1. Granite aggregate & asphalt emulsion are combined onsite. 2. The slurry is applied to the existing asphalt in one or two lifts.
- 12. Micro Surfacing Benefits 50% – 70% less $ than conventional asphalt overlay or mill & overlay. Maintains existing roadways at a higher level of service.
- 14. Chip Seal / Surface Treatment
- 15. Chip Seal Types Single Chip Seal Double Chip Seal Cape Seal
- 16. Chip Seal Process Description 1. Apply a thick layer of asphalt emulsion 2. Apply a layer of granite aggregate
- 17. Chip Seal Benefits Chip Sealing is the most cost effective resurfacing technique available. When topped with fog seal, Chip Seal takes on the appearance open grade asphalt.
- 20. Cold In-Place Recycling Process Description 1. 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. Cold In-Place Recycling Benefits Much less $ than remove/replace. Removes entire cracking network. Minimizes disruption to public. Adds significant structural integrity. Reuses existing materials. Saves taxpayer dollars.
- 22. Cold In-Place Recycling Discussion…
- 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. Full Depth Reclamation Benefits Half the cost of remove & replace. Removes entire cracking network. Simplifies road widening projects. Adds significant structural integrity. Reuses existing materials. Saves taxpayer dollars.

- 27. Paying the Right Price… VS Piggybacking Competitive Bidding
- 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 Larger A. Competitively Bidding i. Use Good Specifications ii. Hold the Contractor to the Specifications iii.
