• Abstract:
  There is increasing pressure from owners, contractors, and the public to open bridge decks sooner to full ; traffic loads. As a result, a set of criteria or guidelines is needed to determine when concrete bridge decks can ; safely be opened. Today, current practice allows many bridge decks and concrete pavements to be opened to traffic ; once a desired compressive strength is achieved from a representative field-cast test cylinder. Though generally ; untrue, many believe that this strength value serves as a measure of the durability of the placed concrete. In a ; collaborative research effort between Texas Department of Transportation and researchers at Texas Tech ; University, studies were undertaken to collect research data that could potentially lead to the development of new ; guidelines as to when bridge decks can be open to (a) construction traffic and (b) full traffic without sacrificing ; concrete durability. This report presents detailed findings of two research thrusts: compressive strength and ; maturity curves commonly used on bridge deck concrete mixes and comparative assessment of the effectiveness of ; three curing methods that led to the development of a framework for a Strength-Durability Index (SDI).
