Self-Consolidating Concrete for Cast-in-Place Bridge Components
Self-Consolidating Concrete for Cast-in-Place Bridge ComponentsTRB recorded a series of videos in February 2017 that featured research from National Cooperative Highway Research Program (NCHRP) Report 819: Self-Consolidating Concrete for Cast-in-Place Bridge Components. The report presents recommended guidelines for the use of self-consolidating concrete (SCC) in cast-in-place highway bridge components. These guidelines address the selection of constituent materials, proportioning of concrete mixtures, testing methods, fresh and hardened concrete properties, production and quality control issues, and other aspects of SCC. The videos discuss the research scope and approach, small-scale lab-mixed concrete specimens, full-scale ready-mixed concrete specimens, and proposed changes to the AASHTO Load and Resistance Factor Design (LRFD) Bridge Design and Construction Specifications. The videos are available on-demand at no cost. The slides are available. |
Selecting and Specifying Concrete Surface Preparation for Sealers, Coatings, Polymer Overlays, and Concrete Repair
Selecting and Specifying Concrete Surface Preparation for Sealers, Coatings, Polymer Overlays, and Concrete RepairThis guide provides owners, designers, specifiers, contractors, and manufacturers with the tools needed to select and specify the methods for preparing concrete surfaces prior to the application of a protective system or repair material. Surface preparation is the process by which a sound, clean, and suitably roughened surface is produced on a concrete substrate. Surface preparation includes the removal of laitance, dirt, oil, films, paint, coatings, sound and unsound concrete, and other |
Construction Procedures and Specifications for Bonded Repair and Retrofit of Concrete Structures using FRP Composites
Construction Procedures and Specifications for Bonded Repair and Retrofit of Concrete Structures using FRP CompositesConstruction Procedures and Specifications for Bonded Repair and Retrofit of Concrete Structures using FRP Composites is designed to assist State Department of Transportation (DOT) construction and maintenance operation staff develop knowledge of project requirements of FRP repairs, substrate surface preparation methods, and procedures and steps for installation of FRP systems. Topics covered in this course include:
The success of repairs and retrofit of concrete structures using FRP Composite is dependent on State Department of Transportation (DOT) construction personnel taking an active role in ensuring construction procedures and specifications are adhered to. Hence, knowledge of proper construction procedures and specifications for FRP projects is necessary to control quality of work. |
FHWA Post-Tensioning Installation and Grouting Manual
FHWA Post-Tensioning Installation and Grouting ManualFHWA recently completed updating the Post-Tensioning Installation and Grouting Manual. This manual has been a valuable and frequently referenced resource for the bridge community and the updated manual has incorporated many recent changes in the post-tensioning state-of-practice, including new post-tensioning components, new testing procedures, and detailing criteria for longer service life- protection levels. |
