Description

This course presents a methodology to rehabilitate post-tensioned reinforced concrete box girder bridge decks using a thin Ultra-High-Performance Concrete (UHPC) overlay. While the emphasis is on post-tensioned box girders, the methodology can be extended to other bridge types, such as slab on girder bridges.

Topics Include

• Review of previous work to rehabilitate concrete bridge decks using UHPC, including both slab on girder and box girder bridges
• Explanation of UHPC material characterization studies and selection of a material for the overlay
• Use of numerical modeling results to check girder stresses and deflection along with suggested modeling techniques
• Discussions of experimental results from a half-scale specimen to demonstrate the performance of the overlay under laboratory conditions
• Best practices to install the overlay
• Construction specifications

What You Will Learn

By the end of this course, students will have a general understanding of:

• Benefits and drawbacks to UHPC overlays, including lessons learned
• Importance of deck preparation to ensure overlay durability
• Numerical modeling results to check girder stresses and deflection along with suggested modeling techniques
• Differences between commercially available and non-proprietary UHPC mixes
• Importance of evaluating bridge response during the overlay process

Who Should Attend

Anyone involved in the maintenance and rehabilitation of post-tensioned reinforced concrete box girder bridge decks, including owners, designers, structural engineers, contractors, and construction QA/QC staff.

Cancellation Policy

To cancel your registration and receive a refund less a $75 processing fee, you must notify TechTransfer at least five (5) working days before the course is scheduled to begin. Notifications must be made in writing and sent by email to registrar@techtransfer.berkeley.edu. We reserve the right to charge the full course fee if proper notification is not sent to TechTransfer. We don't offer refunds for classes with registration fees of $75 or less.

In lieu of canceling your registration, you have three additional options: you may (1) transfer your registration to another class, (2) receive a tuition credit for the total amount, useable toward a future class, or (3) send a substitute in your place. Please contact us at least 5 full working days before the class is scheduled to begin so we may process your request.

If you’ve registered for a self-paced class, you cannot receive a refund once you start the class.

We recommend you discuss any possible problems or online security issues with your IT person before you register for any online classes. If you are worried about connectivity issues, please contact the online training coordinator the week before the class to schedule a time to test your system. If you do not test your system and you have technical issues during a live online class, we will not provide a refund.
