22 CHAPTER 3 Interpretation, Appraisal, and Application This chapter provides an interpretation of the findings in Adopting quality control measures for producing SCC leads terms of highway engineering practice. Recommendations for to enhanced durability and longer life expectancy of bridge revisions to the AASHTO LRFD Specifications are presented structures. Eliminating the need for vibration in precast bridge in Attachment A. Suggested methods for testing SCC are elements also provides a potential for enhancing the manufac- described in Attachment C. Guidelines for quality control turer's environmental, health, and safety conditions. testing, acceptance specifications, and proportioning of SCC The standard test methods and others (e.g., slump flow and for precast, prestressed concrete bridge elements are provided T-50, J-Ring flow, column segregation, and VSI) can be used in Attachment C. These guidelines can be of particular interest to assess workability characteristics of SCC. Based on this to bridge engineers and specifiers, concrete producers, testing project's findings, filling capacity and surface settlement test laboratories, and manufacturers; will facilitate successful use of methods are recommended for use in evaluating the filling SCC; and will contribute to its acceptance. capacity and static stability of SCC.
