Preservation Education

For 45+ years, Gee Asphalt Systems, Inc. has been conducting long-term research on the most effective asphalt preservation methods while our clients have reaped the benefits. Additionally, extensive FHWA, FAA, NAVFAC, MDOT, and AZDOT research all show that strategic asphalt preservation can greatly extend the life of asphalt pavements to sustain streets, roadways and highways, airports, and commercial pavements.

Whether you need training for a large group or smaller one-on-one learning experiences, we offer technical presentations at your location and project tours tailored to your pavement management needs. You can rely on our field experts to give you an unbiased — just the facts — whole picture on issues specific to your industry or cross-references to our studies as a base for your own research on Asphalt Preservation.

While there are several popular ways to help prolong the life of pavements, not all methods are equal in effectiveness, cost and environmental impact. One method, Coal Tar Sealant has quickly become of significant concern. Increasing studies have shown coal tar coatings to be prone to shrinkage, cracking and accelerated pavement degradation. Plus, USGS data confirmed that coal tar releases up to 1000 times greater toxins into the watershed than those released by asphalt pavement or asphalt based coatings. Read more here.
