1 Warm Mix Technology SEAUPG Nashville,Tn. Larry L Michael Asphalt Consultant Warm Mix Technology Reduce Mixing and Compaction Temperature Reduce Fumes Reduce Fuel Costs Improve Workability Improve Density Extend Paving Window Improve Quality CONCERNS: Costs Process Binder Storage Tanks PG Binder Grade Long Term Performance DOT Acceptance There s No Smoke Available WMA Technologies Processes include: WAM Foam Shell/Kolo Veidekke Zeolite Eurovia/Hubbard Construction Sasobit Sasol Int./Moore and Munger Evotherm - MeadWestvaco New processes Sasobit Fischer-Tropsch waxes Different than naturally occurring asphalt waxes in structure and physical properties Higher melting point Lower penetration Higher viscosity Higher molecular weight Sasobit Frankfurt International Airport Renovation of Runway North, Sectors & 2 Frankfurt Airport Old concrete runway had to be removed and replaced under traffic Work only possible in night shifts between 0:30 pm and 6:00 am 7 ½ hours from demolition of concrete to plane landing on new asphalt Any delay in construction would mean major upset in European air
2 Frankfurt Airport Asphalt mixture laid at low temperature Better compactability Increased resistance to deformation at high temperatures Frankfurt Airport Bear heaviest aircraft in 2-3 hours Reduced cooling, key to 300-step project QUESTION First runway in 200 Second runway in 2003 Contract was in both cases a renovation of binder course and wearing course The wearing course was to have lowest possible permeability Contract called for an SMA 0/Hamburg with % less voids than usual Hamburg lies in a very wet climate, frequent freeze/thaw cycles and heavy use of deicing fluids are demanding a premium asphalt construction Will Sasobit have a negative effect on mix quality? NCAT Evaluation Improved compact ability to 90 0 F Did not affect resilient modulus Did not increase rutting potential (APA) Cure time to open to traffic is not an issue Moisture damage with lower temperature may be an issue Anti-aging Properties Field Trials. 45% RAP 9mm Base 2.
