Technical Exchange Page

This page has been designed for the posting and exchange of technical documents specifically related to Bridge Preservation.  Entries will be listed in the order that they are posted and filed in their appropriate categories on the TSP2 Web-Site.  Postings can be made by State Agencies, FHWA, and other approved organizations.

This site will be used to post new technologies and practices that are presented at Partnership Meetings and during Monthly Regional Partnership calls.

PennDOT’s Bridge Preservation Programs & Best Practices

Scott Snyder, PennDOT’s Bridge Maintenance Quality Assurance Manager has prepared a 26-slide presentation outlining his agency’s bridge preservation best practices. The slides contain photographs illustrating various conditions, treatments, and techniques.

Rapid Concrete Bridge Deck Overlays [2018-10-09]

Michael M. Sprinkel, P.E., Associate Director of the Virginia Transportation Research Council has produced a 29-slide Power Point presentation on concrete bridge overlays. The presentation describes Virginia’s experience with the use of three types of overlay:

  1. LMC (Latex Modified Concrete)
  2. LMC-VE (Latex Modified Concrete with very early hardening cement)
  3. SF (7% Silica Fume concrete)

When overlays were placed on bridges where lane closures would cause major traffic congestion, LMC-VE overlays were found to be the most cost effective.

Bridge Preservation Guide

State departments of transportation (DOTs), local agencies, and other bridge owners face significant challenges in addressing the needs of their aging infrastructure. Due to limited funds and increased competition for funds among highway assets, bridge owners are challenged to cost effectively preserve and maintain their bridges to support overall highway mobility. However, having a “worst-first” approach to bridge management by focusing only on replacing poor bridges while ignoring the maintenance needs of good and fair bridges is inefficient and cost-prohibitive in the long term.
A successful bridge program seeks a balanced approach to preservation and rehabilitation/replacement. Bridge owners are striving to be more strategic by adopting and implementing systematic processes for bridge preservation as an integral component of their overall asset management.

VDOT’s Laser Coating Removal Research [2018-11-13]

The Virginia Department of Transportation is conducting research investigating the efficacy of using high-wattage lasers for removing coatings from existing bridges. High-wattage, hand-held lasers are now commercially available at costs that have increased their potential value for use in removing coatings on bridges. The objective of this project is to determine the feasibility of using high-wattage lasers to remove coatings from VDOT bridges.
