Elastomeric Concrete for Bridge Deck Expansion Dam Headers

Pennsylvania Department of Transportation (PennDOT) currently approves Elastomeric Concrete products for use on Pennsylvania roadways based primarily upon the performance of the products during field evaluations. Field evaluation however takes time, and relies heavily on the characteristics of the evaluation site. A major objective of this project was to develop a set of specifications that will enable PennDOT to evaluate Elastomeric Concrete materials in the laboratory rather than in the field. This document describes the efforts put forth by the project team to develop the specifications. It includes a comprehensive literature review, review of existing practices and development of a testing program. The work presents a framework by which Elastomeric Concrete can be tested, evaluated and specified. The resulting specifications will be considered for implementation by PennDOT on a later date.
