This report develops a framework for organizing risk-based decisions about design, maintenance, and operation for the Colorado Department of Transportation (CDOT) applying to various types of facilities. It also provides illustrative examples for the use of the proposed framework. CDOT has an opportunity to be a national leader in assessing risks, vulnerabilities, consequences and outcomes through the implementation of a risk-based framework for facility design, operations and maintenance.
Internally cured concrete has been rapidly emerging over the last decade as an effective way to improve the performance of concrete. Internal curing (IC) holds promise for producing concrete with an increased resistance to early-age cracking and enhanced durability. It is a simple and effective way to cure concrete.
This study is the evaluation of two thin bonded epoxy overlays. These two products were compared on the basis of physical properties, including mean texture depth, surface friction, bond strength, ability to stop chloride intrusion, and anti-icing properties, as well as traffic safety and cost. Both overlays worked as intended when they were initially applied on the bridge decks. Mean texture depth and friction testing have shown that they both provide a durable wearing surface with good traction.
