Abstract
Since 1992 Golder Associates has been working with the municipality of Anchorage, Alaska, to evaluate the causes of pavement distress throughout the municipality. Design and construction changes have been recommended and implemented. The performance of pavements both before repair and after redesign has been monitored and evaluated. Surficial heave rates have been measured, ground temperature variations have been documented, crack patterns have been mapped, and soil profiles have been noted at various sites around the municipality. In locations where drainage and insulation recommendations have been implemented, improved pavement performance has been observed. This research presents case histories outlining the conditions initially observed in the distressed pavements. It also traces the performance of the pavements after their being rebuilt according to recommendations.
