  • Hopwood, Theodore (PI)

Grants and Contracts Details


Conduct a literature review. Survey selected SHAs and KYTC Districts to obtain infol1nation/opinions about expansion joint/header installation, perfol1nance and special maintenance requirements/practices. 2. Obtain cost, perfol1nance data, specifications, installation instmctions and maintenance requirements on specific joint designs fi'om manufacturers/material suppliers. 3. Develop guidance on joint selection enumerating prefeITedjoints for both new construction and maintenance. Identify joint perf0ll11anCe tests that may be used to evaluate new joints after they are placed. 4. Review the best performing deck joints/details (based upon Objective I) and identify potential areas for joint perfol1nance enhancements. Interface with joint/material manufacturers to implement enhanced joint materials/designs. 5. Assist in the development ofKYTC experimental projects incorporating bridge expansion joints that offer improved performance. Monitor the placement of experimental joints during construction.
