Portland-cement concrete rheology and workability : final report / by Wong, G. Sam.(CARDINAL)312566; Turner-Fairbank Highway Research Center.(CARDINAL)286897;
Includes bibliographical references (pages 97-109).Final report;"Methods for determining the workability of freshly mixed Portland-cement concrete with slumps less than 51 mm (2 in) were investigated. Four potential methods to determine the workability of concrete were proposed for evaluation and development. The methods included two moving-object methods, one free-orifice method, and a vibrating-slope method. The report outlines modifications to these existing techniques and equipment to permit the measurement of rheological properties at two or more shear rates. The vibrating-slope apparatus (VSA) was selected for further development."Sponsored by the Office of Infrastructure Research and Development, Federal Highway Administration, under contract no.

Pendulum testing of fixed-end W-beam guardrail : FOIL test numbers 96P001, 96P002, 96P003, 96P004, 96P005 and 96P006 / by Brown, Christopher M.(CARDINAL)770799; United States.Federal Highway Administration.Office of Safety and Traffic Operations Research and Development.(CARDINAL)172825; MiTech Incorporated.(CARDINAL)317082;
Includes bibliographical references (page 79).Background -- Scope -- Test matrix -- Pendulum -- Test article -- Data acquisition -- Data analysis -- Results -- Conclusion -- Appendix A: Data plots of data obtained from accelerometers and strain gages -- References.Test report;This report contains the test setup and results from six pendulum crash tests performed at the Federal Outdoor Impact Laboratory (FOIL) located at the Turner-Fairbank Highway Research Center in McLean, Virginia. The tests were conducted on steel W-beam rail elements rigidly anchored at both ends (a four-post configuration). The tests were conducted as part of an ongoing research effort to obtain baseline data on the dynamic properties of standard steel W-beam in order to develop a design envelope for a fiber reinforced plastic rail element. The nominal weight of the FOIL pendulum with a rigid nose assembly was 912 kg. The tests were conducted at nominal speeds ranging from 20 km/h to 35 km/h. Results from the tests are presented as test summaries of data, graphs of data, and photographs taken before, during, and after the tests.Performed by MiTech Incoporated for the Federal Highway Administration, Office of Safety and Traffic Operations Research and Development, under contract no.

Measurement and specification of construction quality. by Hughes, Charles S.(CARDINAL)314592; United States.Federal Highway Administration.Office of Engineering & Highway Operations Research and Development.(CARDINAL)286896; Brent Rauhut Engineering, Inc.(CARDINAL)311391; Turner-Fairbank Highway Research Center.(CARDINAL)286897;
Includes bibliographical references (pages 159-173).Introduction -- Working plan for conducting research -- Literature search -- Description of field projects -- Sampling and testing -- Data analysis -- Conclusions and recommendations -- References -- Bibliography.Final report;This study consisted of testing six projects: three hot-mix asphalt concrete (HMAC) and three portland cement concrete (PCC). The primary objectives were to: (1) determine how current quality control test results vary in construction projects and how this variability affects pavement performance, (2) assess the suitability of current methods of quantifying materials and construction quality and quality variability, and (3) develop and improve methods that minimize current shortcomings. Volume I of this report contains information about the data analysis.Performed by Brent Rauhut Engineering, Inc. and sponsored by the Federal Highway Administration, Office of Engineering Research and Development under contract no.

Long-term effects of cathodic protection on prestressed concrete bridge components / by Hartt, William H.(William Handy),1939-(CARDINAL)286956; United States.Federal Highway Administration.(CARDINAL)139839; Florida Atlantic University.Center for Marine Materials.(CARDINAL)286955;
Includes bibliographical references (pages 67-68).Introduction -- Hydrogen embrittlement -- Effect of cathodic polarization on tendon-to-concrete bond -- Evaluation of remote monitoring and control systems -- Conclusions -- References.Final report;While cathodic protection effectively reduces or stops ongoing corrosion of reinforcing steel in concrete, applicability of this technology to prestressed members has been limited because of concerns regarding possible bond loss and hydrogen embrittlement. Within this context, the present research was intended as a comprehensive, multifaceted undertaking to elevate the understanding of prestressed concrete cathodic protection to the same level as for reinforced concrete. The program involved four components: (1) constant extension rate testing (CERT) of precorroded tendon wires, (2) cathodic overprotection of precorroded, pretensioned beams with evaluation for hydrogen embrittlement susceptibility, (3) concrete block pull-out tests to determine any effect of cathodic protection on the tendon-to-concrete bond, and (4) evaluation of a commercially available remote monitoring and control hardware and software system for application to prestressed concrete cathodic protection.Performed by Florida Atlantic University, Center for Marine Materials, for FHA Office of Engineering Research and Development, under contract no.
