Field Evaluation of Methods to Minimize Transverse Glulam Deck Deflection Phase III

The purpose of this study is to determine localized structural performance of the previously constructed demonstration bridge in Delaware County, Iowa to determine the cause of asphalt overlay cracking, assess the appropriateness of the existing asphalt overlay mix, and formulate a new asphalt mix design that performs better on transverse glulam decks.
