Asphalt Systems, Inc. Salt Lake City , Utah
30 years preserving asphalt Innovative preservation materials Focus on asphalt preventive maintenance for: Federal, state, and local governments Private industry Residential
3
What Is GSB-88? Complex asphalt emulsion Applied as a fog seal
Surface oxidation retardant Rebinding agent Sealant Surface rejuvenator Cosmetically enhancing Can be used as a construction seal
4
Why GSB-88? Asphalt comes from the “bottom of the barrel” of the refining process As refining techniques get better the quality of asphalt decreases Poorer asphalt binder Higher asphalt prices GSB-88 uses natural occurring asphalt that has never been refined High quality resins and polar compounds
5
Applying GSB-88 Standard asphalt distributor
Rate: .10 to .15 gallon per sq/yd Standard: .12 gallon per sq/yd Even and accurate application Sand distribution Rate: .3 lb to 2 lbs per sq/yd Standard: .3 lb to .75 lb per sq/yd

8
Preserving the Binder The leading cause of asphalt deterioration is surface oxidation GSB-88 is significantly more resistant to surface oxidation than refined AC GSB-88’s unrefined resins rebind macro and micro maintaining surface integrity Reapplication of GSB-88 can virtually eliminate surface oxidation
9
GSB-88 Pavement Selection
Best candidates Newer pavements Shoulders & rumble strips Residential roads Excessive weathering Premature raveling Low volume roads Parking & rest areas Airports Poor candidates Older pavements Where skids are marginal High traffic roads Where structural failure already exists Where surface oxidation is a minor factor in degradation
