The objective and scope of this research was to investigate the effects of construction loads and vibrations on typical newly poured reinforced concrete bridge decks. A compendium was developed that takes into consideration all the factors influencing the effects of construction loads and vibrations on the performance reinforced concrete bridge decks, in particular, the structural cracking of the concrete. The parameters considered for the evaluation stages were age of concrete, stage and sequence of pours, curing procedures, heat of hydration, strength gain, thermal changes, type of construction, adjacent traffic, adjacent pile driving, and construction equipment. The identification process consisted of a comprehensive literature review and questionnaire survey. Due to the complexity of the subject, limited and often conflicting information were identified. An experimental program was conducted to determine the modulus of elasticity of concrete as well as the maximum curvatures that fresh concrete can withstand. A computer program was developed to identify the best possible pouring sequence for continuous span bridges.
