This letter is in response to the GSB-88 ® seal coat we tested here at this property. As you are fully aware the test section was an area that was overlaid late in the season during the previous year. As a result it showed extreme raveling with excessive loose aggregate and a very porous surface. The subsequent test application of GSB-88 ® has corrected this problem and has no doubt prolonged the life of this surface. It is evident the surface would have to have been replaced if not for the
GSB-88 ® application. I feel your preventive maintenance system of sealing and preserving asphalt pavement is one our industry is ready for. Thank you for your assistance in providing a solution to our problem.
