Case Studies
CASE STUDY 1
HOLDING TOGETHER A 55 YR OLD ROAD
This section of road constructed in 1967 was abandoned when a nearby railroad crossing was closed following the construction of I-70. A company took ownership of the pavement in 2009. The road was sealed in the spring of 2011 with GSB-78®, then sealed again with GSB-78® in 2016. In 2022, at 55 years of age, the road continues to be held together by GSB-78® and crack seal (a testament to GSB-78® and the quality AC binders used 55 years ago).

CASE STUDY 2
SEALING & PROTECTING A 13-YR-OLD PARKING LOT
This coffee shop drive-thru parking lot pavement is 13-yer-old (constructed in 2009). It was sealed with GSB-78® in year 2 (2011) and in year 7 (2016). In year 13 (2022), the GSB-78® treatment continues to seal and protect the pavement.
2022 TREATED TWICE (2011 & 2016)

CASE STUDY 3
FIXING A PROBLEM PAVEMENT IN ALASKA
After a contractor’s sub-par equipment and experience led to a low density, segregated HMA pavement (which would never survive the harsh winters and studded snow tires), ASI offered Unalakleet, Alaska a solution (i.e., a double application of GSB-78®) to “fix and protect the surface” from the harsh weather and studded snow tires.
THE PROBLEM ⇢
A low density, segregated HMA road pavement.

CASE STUDY 4
MILITARY AIRFIELDS, Mitigating Asphalt-Based FOD
Airfield Type & Location:
A military airfield in the Southwest region of the USA servicing multiple aircraft, including high performance fighters.
CUSTOMER QUOTE:
"A heavy application of GSB-88® was able to return runway to full service and later site visits confirmed that the application remained effective up to the day it was replaced with an overlay 20 months later. Based on observed pavement condition with the facilities’ pavement engineer at 18 months, two months prior to overlay, the GSB-88® application appeared to be able to continue to maintain the readiness of the runway for some time into the future.” — Military Pavement Subject Matter Expert (SME)

Pre-Application Binder Failure
PROBLEM: Premature binder failure (FOD) on critical runway. Standard asphalt emulsions failed to resolve the problem.
18 months after GSB-88® Application
SOLUTION: A heavy application of GSB-88®, along with patching in the most severe areas.
Airfield Type & Location:
A commercial airport in the Southeast region of the USA.
CUSTOMER QUOTE:
"Areas of the ramps and taxiways were routinely taken out of service for FOD removal, sweeping, and clean-up. The airport couldn’t gain control of the FOD problem once the binder started failing. Then we had the entire airport treated with a P-608 preservation treatment. The FOD issue was immediately mitigated. The serviceability of the airport increased dramatically simply from the P-608 treatment, which resulted in no loose aggregate."
— Airport Manager
Pre-Application
PROBLEM: Asphalt-based FOD caused from the failing asphalt binder of an aged slurry seal surface treatment.
Post Application
SOLUTION: The entire airport was treated with a P-608 preservation treatment employing GSB-88®.
CASE STUDY 5
RURAL ROADS IN SNOWY NORTH
CUSTOMER PROBLEM:
- Micro and slurry delaminated and does not want chip seal.
- Treatment must work in “wide open spaces” and on roads that get dirty and heavy truck traffic.
- Winter Low: - 20° F
- Summer High: 90° F
- Snow Plowing
- Tire Chains/Studs
- Crushed Aggregate
