Field Implementation and Monitoring of an Ultra-High Performance Concrete Bridge Deck Overlay

项目名称：	Field Implementation and Monitoring of an Ultra-High Performance Concrete Bridge Deck Overlay
摘要：	Overlays are placed on existing concrete bridge decks to increase cover for the deck reinforcing steel, improve rideability, and improve skid resistance. Previous research has demonstrated that ultra-high performance concrete (UHPC) has the potential to increase service lives of bridge deck overlays, and subsequently, the underlying concrete deck, because it has exceptional durability properties and contains silica fume that facilitates bond to substrate concretes. This research project will document, monitor, and assess the field implementation of a UHPC overlay produced with local materials on a bridge in Socorro, NM. This will be the first non-proprietary UHPC overlay constructed in the U.S. The research project consists of a comprehensive literature review to identify best practices for UHPC technologies and overlay construction methods. Short and long-term monitoring plans will then be developed for assessing the performance of the constructed UHPC overlay. Data collected during construction will include weather data, construction sequence, and other observations that might influence the quality of the completed project. After construction, the short and long-term monitoring plans that include mechanical, physical, and nondestructive testing, will be initiated, and the assessment of the initial measurements will be reported in the final research report.
