This project has consisted of developing draft specifications & mixture designs for SCC used in the construction of drilled shafts for the B. Some of the tests conducted including compressive strength & permeability testing of cores extracted from experimental casings made from SCC and conventional concrete (separately); CSL testing on all permanent shafts; gamma-gamma testing on select shafts; internal temperature testing from thermal sensors embedded in shafts during placement.
The project was let in multiple phases, with construction in each phase being observed & documented by researchers, in addition to conducting numerous tests to evaluate the quality of the concrete.
TRB is uniquely suited for this purpose for many reasons: TRB maintains an extensive com- mittee structure from which authorities on any highway transportation subject may be drawn; TRB possesses avenues of communications and cooperation with federal, state, and local governmental agencies, univer- sities, and industry; TRBâs relationship to the Academies is an insurance of objectivity; and TRB maintains a full-time staff of specialists in high- way transportation matters to bring the findings of research directly to those in a position to use them.
The program is developed on the basis of research needs identified by chief administrators and other staff of the highway and transporta- tion departments and by committees of AASHTO.
The Boardâs varied committees, task forces, and panels annually engage about 7,000 engineers, scientists, and other transportation researchers and practitioners from the public and private sectors and academia, all of whom contribute their expertise in the public interest.
