Abstract:

The objective of this report is to determine the most effective method for bridge deck overlay construction and repair by assessing current practices; examining new products and technologies; and reviewing NCHRP (National Cooperative Highway Research Program) guidelines, state standard specifications, ASCE (American Society of Civil Engineers) infrastructure ratings, and original bridge core chloride penetration data. Based on the review, this report offers the following conclusions. Latex modified concrete (LMC) overlays perform well, provide a long service life, and are the most commonly used method of bridge deck rehabilitation. Ohio considers microsilica concrete (MSC) overlays as state of the art due to their lower permeability. Superplasticized dense concrete (SDC), fly-ash modified concrete (FAMC), and polymer modified concrete (PMC) are other acceptable choices for bridge deck overlays. Silane or epoxy sealers may be used as a low-cost preventative approach to slow the deterioration of concrete bridge decks. Waterproofing membranes have produced mixed results but have the potential to be an effective system if installed correctly. Rosphalt® can be an expensive material but offers benefits such as minimizing traffic disruption due to shorter installation periods and increased durability. The two most important conclusions drawn from this research are the importance of a comprehensive approach when selecting a bridge deck rehabilitation method, and the importance of properly following instructions when installing overlays or waterproofing membrane systems.
