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
