Depressed transverse cracks are a common and costly pavement distress occurring on many roads. Transverse cracks typically develop when low temperature-induced tensile stress exceeds the tensile strength of the pavement and run perpendicular to the pavement lane. When this type of distress occurs, motorists experience an uncomfortable ride. Nicollet County Highway Department in New Ulm, Minnesota, had been treating depressed, transverse, and longitudinal cracks by first applying a tack coat, followed by the installation of a hot mix asphalt repair that proved to be costly and labor intensive, in addition to requiring multiple trucks, a roller, a fairly large crew, and daylong traffic interruptions.
To provide a long-term repair to the depressed transverse cracks, Mastic One® was installed along a roadway heavily trafficked by cars, trucks, and large farming vehicles. A unique, hot-applied polymer modified asphalt-based material with engineered aggregate, Mastic One® is a highly adhesive, flexible, durable, and waterproof mastic with a service life exceeding five years and is specifically designed for wide transverse cracks and distressed surface areas in both asphalt and concrete pavements making it the preferred repair material.
