Abstract

Counties and cities in Southeast Michigan have used concrete pavements for nearly 100 years to provide long-lasting, durable streets and roads. Issues of concrete durability have arisen with some of the pavements built after 1990. In order to evaluate the causes of spalling and other deterioration methods, the National Concrete Pavement Technology Center (CP Tech Center) was asked to study the concrete from a number of the pavements, evaluate the causes of the distress, and offer recommendations for improvements. Of particular concern are the roles of coarse aggregate type (limestone or blast furnace slag), alkali-silica reactivity (ASR), and the air entrainment system in the hardened concrete on the joint deterioration distresses that are being observed.
