Over the last several years Colorado asphalt pavements have experienced early deterioration and premature pavement failures. The study evaluated the product, Gilsonite. Gilsonite is a naturally occurring solid hydrocarbon and is currently being marketed as a asphalt modifier. Gilsonite is a modifier which is intended to increase the stability of the pavement and help resist rutting often found on today's pavements. Following the 3-year evaluation, the data indicates the addition of Gilsonite, although it does appear to reduce or retard rutting, tends to harden the pavement creating a pavement structure which is more susceptible to premature cracking. The cracks appeared at a much faster rate and the cracks tended to deteriorate quicker and to a greater extent in the Gilsonite section.
