Abstract

Since the majority of the pavement network in the United States is already constructed1, most of the attention has turned toward maintaining and reconstructing existing roads. Through routine maintenance of the wearing surface, the life of a pavement is greatly extended and long-term costs greatly reduced. Pavement maintenance treatments range from quick and inexpensive crack-sealing to more intensive surface milling followed by a costly asphalt overlay. One treatment recently put to mainstream use in Utah is microsurfacing. Microsurfacing is often described as the most durable and stable of the available slurry seals. Like other slurries it protects against water ingress, retards oxidation of asphalt, adds skid resistance, improves pavement aesthetics, and delays crack propagation. Microsurfacing, in particular, resists shear deformation and thus can fill pavement ruts and be applied in high-traffic urban environments.
