ACI 345R-11 PDF Download

The text describes the purpose and importance of concrete highway bridge decks. It states that the deck serves both structural and functional purposes by safely transferring forces and providing a smooth and safe riding surface for vehicles. The construction and condition of the deck directly impact the performance and serviceability of the bridge.

The text also highlights common defects that can occur in bridge decks, such as roughness, cracking, spalling, scaling, and poor skid resistance. It emphasizes the significance of paying attention to design, materials, construction practices, and environmental factors to prevent these defects. The goal is to achieve smooth and durable decks that require minimal maintenance throughout the lifespan of the structure.

The text acknowledges that many decks remain in good condition for years, but when deficiencies occur, they usually fall into specific categories. The guide aims to address these issues by discussing the contribution of different aspects of deck construction to defects and providing guidelines based on theory and experience to reduce the likelihood of occurrence to acceptable levels.
