This study examines the seismic evaluation of concrete bents of highway bridges designed and implemented according to the s regulations. Compared with the older codes, s codes have more complex details for connections which are evaluated by experimental .

    This paper presents the results of an experimental study to determine the effective prestress force in two full scale prestressed concrete bridge beams that were removed from a bridge structure after a period of 28 years in service. An average prestress loss of 78 percent was determined for the two specimens. 5. Project Evaluation A comprehensive project evaluation is important to understand the constraints of pavement design including drainage, pavement finish surface grade, and existing subgrade conditions. Generally, existing drainage and subgrade conditions will dictate the type and thickness of .

    Concrete temperatures are affected by the mix-water temperature, aggregate temperatures, cement type and admixture type. Optimum concrete temperatures will aid with setting, early strength development, proper curing and ultimately aid in achieving a higher quality concrete. Hot concrete . This digest summarizes much of the current research in the U.S. relating to concrete paving. It covers projects that were either underway or were completed as of Subject areas include performance evaluation, design, construction, specifications.

Workability characteristics of the fresh concrete are analyzed and hardened concrete properties tested in this research are compressive strength, chloride ion permeability, and creep and drying shrinkage properties. FINISH a concrete mix. Concrete that is stiff or dry may be difficult to Handle, Place, Compact, and Finish and, if not constructed properly, will not be as strong or durable when finally hardened.

A slump test can be used to measure the workability of concrete. See CHAPTER 3 Concrete Testing. The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete design, construction, and materials, who share a commitment to pursuing the best use of concrete.
