  • 1. ChemCo Systems
  • 2. SFO SAS Bay Bridge Epoxy Asphalt Paving ChemCo Systems
  • 3. Test Pave SFO SAS Bay Bridge Epoxy Asphalt Paving A Test Pave was completed to demonstrate the ability to achieve desired physical properties of epoxy asphalt concrete to the California Dept. of Transportation before applying the material on the bridge deck. ChemCo Systems
  • 4. Paving the Bay Bridge: Epoxy Tack Oil Bond Coat Machine SFO SAS Bay Bridge Epoxy Asphalt Paving Machine meters correct amount of each component of the epoxy tack oil and pumps it to the applicator at a set flow rate. The machine has enough storage to tack 1.5 lanes before re-filling. ChemCo Systems
  • 5. Paving the Bay Bridge: Epoxy Tack Oil Bond Coat SFO SAS Bay Bridge Epoxy Asphalt Paving ChemCo Systems’ Tack Oil is applied before each layer of epoxy asphalt concrete to bond the epoxy AC to the deck. ChemCo Systems
  • 6. Paving the Bay Bridge: Production at the Asphalt Plant SFO SAS Bay Bridge Epoxy Asphalt Paving 1. Batch is dumped into front loader 2. Batch Temperature checked for QC purposes 3. four consecutive 3 ton batches loaded into a truck and transported to the bridge deck. ChemCo Systems
  • 7. Paving the Bay Bridge: Epoxy Asphalt Concrete SFO SAS Bay Bridge Epoxy Asphalt Paving Equipment: - Paver - Transport Shuttle Buggy - Transport Truck - Rubber and steel tire rollers Note: Transport Shuttle Buggy lifts Epoxy AC from the truck into the paver in order avoid driving in the fresh Tack Oil. ChemCo Systems
  • 8. Paving the Bay Bridge: Epoxy Asphalt Concrete SFO SAS Bay Bridge Epoxy Asphalt Paving Finished Lift being placed down on the East-Bound Deck ChemCo Systems
  • 9. Paving the Bay Bridge: Epoxy Asphalt Concrete Saw Cut SFO SAS Bay Bridge Epoxy Asphalt Paving Each lane of epoxy asphalt concrete is cut at an angle to remove the edge which may not be thoroughly compacted and to provide a clean surface for the adjacent lane to bond to. ChemCo Systems
  • 10. SFO SAS Bay Bridge Epoxy Asphalt Paving Paving the Bay Bridge: Epoxy Asphalt Concrete Quality Assurance on the Bridge Deck Nuclear Gauge Testing was performed to ensure that proper compaction was achieved on the final driving surface ChemCo Systems
  • 11. SFO SAS Bay Bridge Epoxy Asphalt Paving Paving the Bay Bridge: Epoxy Asphalt Concrete First Layer of epoxy AC on bridge deck (left) before the final lift is placed on the deck. ChemCo Systems
