Understanding material properties is critical in the selection, specification, and design phases of structural rehab projects.
Join Forester University for this live, educational webinar as speaker Johnny Love, National Product Manager at ConShield Technologies, provides an overview of common rehab solutions for culvert repair and the process of evaluating solution options based on situational parameters.
We will take an in-depth look at the following two case studies of structural culvert rehab projects utilizing fine aggregate composite concrete (FACC) applications, including their design, implementation, and post-installation stress strain gauge test results:
Florida State Route 16
A large diameter load-bearing rehab project involving a 156” bolted multi-plate steel pipe that was rehabilitated with FACC in March 2010.
With only 10”-12” of cover between the crown and the busy road above, the structural integrity of the rehabilitation was imperative. Six years after installation, stress testing was conducted to assess the structural integrity, strength, and ductility of the rehabilitated structure. Sensor manufacturer Resensys LLC of College Park, MD utilized a sensor system consisting of four high rate strain SenSpot sensors and one SeniMax data logger and remote communication gateway. Live load testing—with a semi-tractor pulling a flat-bed trailer weighing a total of 83,620 pounds—was used to confirm structural integrity and to ensure the bridge’s capability to withstand its rated load. FDOT’s Bob Kosoy states that the rehabilitated pipe is holding up very well and they are pleased with the results.
Australian rail lines
Involved several culverts of varying diameters running under company-owned rail lines in Australia.
Following rehabilitation, Rockfield Technologies Australia was contracted to complete field inspection and stress strain testing for finite element analysis (FEA).
By participating in this webinar, attendees will:
- Obtain best practice guidelines for assessing pipe and surrounding soil conditions as well as traffic load and other environmental considerations critical to successful rehabilitation
- Learn how to assess and evaluate site-specific criteria for calculating proper thickness of centrifugally cast concrete pipe for fully structural and watertight rehabilitation
- Understand the critical properties for structural performance of a centrifugally cast fine aggregate composite concrete (FACC)
- Feel comfortable writing specifications and assessing input from third-party engineers and licensed contractors
- Identify how to use post-rehab stress strain gauge testing to assess structural integrity of rehabilitated structures
