– Conserving our resources
– Reducing energy cost
– Reducing Greenhouse Emission
– Being more environmentally friendly
– And building a better, long-lasting pavement
And at the same time

– Fear of making a mistake– Meeting voids & asphalt content with
Superpave Mix Design– Meeting skid requirements– Hardness of asphalt with high RAP -
need to use softer virgin asphalt cement…fatigue cracking
– Special mixes like SMA– Limit RAP to 15% when polymers
are used
Barriers to increasing the use of more Recycle

– Light oils are either put in asphalt or left in asphalt during refining
– These light oils boil at above 285oF
– By mixing at below 285oF, the boiling point is never reached…eliminating smoke (vapor) and corresponding smell
No Smoke – No Smell…Why?

– To achieve compaction (density)…run 275oF and foam virgin liquid
– By using a standard liquid 64-22, you produce a much softer product than with virgin mix due to:
• Lower temperature results in less oxidation
• Light oil remains in liquid
• Steam produced from drying the RAP creates an inert atmosphere
High Percentage Recycle Mix with Standard Grade of Asphalt

Assume - $400.00 Liquid – 64-22- $450.00 Liquid when using Recycle- 5.5% Liquid- Processing Recycle Cost – $3.00 / ton- Haul Cost – $3.00 / ton- Aggregate Cost – $10.00 / ton- Plant Processing Cost – $6.00 / ton- Overhead and Profit – $4.00 / ton
1. If State D.O.T. purchases – All Virgin Mix
Tons of Virgin Mix = 120,627 tons
2. If State D.O.T. purchases 50% RAP Mix – 2" Inlay – Contactor gets RAP
Tons of RAP Mix = 166,113 tons
State D.O.T has $5,000,000.00 to spend on mix…no haul, no laydown, milling paid separately
