The original emulsion-based restorative and protective sealer brought to market in 1988
FAA and military pavement experts project that as much as 90% of airfield asphalt pavement deterioration can be attributed to surface oxidation. Early application and timely reapplications (about every five years) of GSB Products can mitigate surface oxidation as a contributing factor in airfield asphalt deterioration.

Extend pavement service life by restoring and protecting the pavement surface
A 27-YR-OLD PAVEMENT AT EXTREME ELEVATION
Only GSB-88® has been used, and the 4th (most recent) application was 2020. PCI ratings from the State Aero website show the condition of this pavement (constructed in 1995) over time and the impact FAA P-608 applications had on PCI:
2012 PCI 77
2015 FAA P-608 application
2015 PCI 87
2018 PCI 84
2020 FAA P-608 application

Problem
HMA pavements (P-401 mixes) are designed to last 20 years, and this runway pavement was failing after 3 years.
Solution
Contractor applied a double application of GSB-78®to add high-performance residual asphalt to the HMA surface binder to hold the HMA aggregate in place and mitigate raveling and FOD.
Problem
HMA pavements (P-401 mixes) are designed to last 20 years, and this runway pavement was failing after 3 years.
Solution
Contractor applied a double application of GSB-78®to add high-performance residual asphalt to the HMA surface binder to hold the HMA aggregate in place and mitigate raveling and FOD.
Two years after application, these photos show that the HMA aggregate is still locked down and FOD is mitigated.
The close-up photo on the left shows the GSB-78® and the aggregate applied with it (white) still working on the surface.
The photo on the right shows the amount of high-performance residual asphalt (compared to "Problem" photos) that is in the voids to seal and lock the HMA aggregate in place.
AVOID AIRPORT CLOSURES
GSB-78® / FAA P-608-r
RESTORATIVE AND PROTECTIVE Seal Coat THAT CAN BE APPLIED AT NIGHT
GSB-78® is a solvent-based, gilsonite-modified, asphalt pavement preservation treatment. Unlike a water-based asphalt emulsion, GSB-78® cures via a chemical process which does not require sunshine or other climatic influences.

ASI allows busy airports to maintain revenue-producing productivity and military airfields to maintain a high state of readiness.
Grand Junction (GJT) airport
Grand Junction (GJT) airport
Main runway was treated at night,
so no lost travel days.
And the treatment performed well for 5 years.
In 2016, Grand Junction airport did not want to close their main runway for several days and lose ops.
So, Armstrong Engineering, with collaboration from ASI, designed a nighttime project with 6-hours working windows for the contractor. This was one of the first pavement preservation seal coat projects in the US executed at night.
A segment of the pavement was treated at 11:00pm (i.e., the treatment was applied, cured, passed friction testing requirements, temporary striping applied). And that same segment of pavement was back open for traffic by 5:00am the next morning.
GJT was so happy with the treatment, it retreated with FAA P-608-R (GSB-78®) again in fall of 2021.
