Wearing course rutting that causes progressive loss of material from the surface is a typical pavement distress occurring in the Central Region of Alaska and other northern states such as Washington and Oregon. In Alaska, concrete with commonly-used additives is already in production and appears to be more durable and cost effective, especially for pavements that are more resistant to studded tire wear. This study is to further identify the optimum concrete mix design, and produce and implement cost-effective, highly abrasion-resistant, and durable concrete for cold region highway applications.
