Why should the City of Council Bluffs choose to implement a long term pavement preservation strategy which includes a highly effective process called GSB-88®? Of course the decision should be based on performance and a lower the cost to the public. Reducing replacement intervals and improving the quality over a longer period of time and lowering cost should be the goal.
Some other very large and important agencies have chosen GSB-88®. The reason the FAA and DoD choose GSB-88® is based on a recent pavement preservation study conducted by the United States Navy Engineering Command. This study compared 10 commonly used coatings including Reclamite, fog seals, slurry coating, micro-slurry, GSB-88® and even overlays over a 5 year period and at over 200 locations. 5 years later 2000+ cores were taken, oils extracted, properties measured and a clear winner rose to the top, GSB-88®. GSB-88® preserved the oils inside pavements better, and longer. The Navy engineers conservatively predicted the doubling of pavement life when properly utilizing GSB-88®.
Even more compelling, when costs of all were compared GSB-88® returned with the lowest life-cycle cost and highest benefit to pavements treated! In fact, GSB-88® performed 2x better than the second best process. No small feat; several times better than chips seals, fog seals and slurry coatings.
For these reasons we recommend that the City adopt GSB-88® as the City of Des Moines, City of Davenport, City of Bettendorf, NDOR, the FAA, DoD and many others have as the preferred method for preserving good city streets, to keep them in good condition, and lengthen the life of our streets.
