Multiple corrosion protection systems for reinforced concrete bridge components ( )
3 editions published in 2007 in English and held by 336 WorldCat member libraries worldwide
Eleven systems combining epoxy coated reinforcement with another corrosion protection system are evaluated using the rapid macrocell, Southern Exposure, cracked beam, and linear polarization resistance tests. The systems include bars that are pretreated with zinc chromate to improve the adhesion between the epoxy and the reinforcing steel; two epoxies with improved adhesion to the reinforcing steel; one inorganic corrosion inhibitor, calcium nitrite; two organic corrosion inhibitors; an epoxy coated bar with a primer containing microencapsulated calcium nitrite; the three epoxy coated bars with improved adhesion combined with the corrosion inhibitor calcium nitrite; and multiple coated bars with an initial 2 mil coating of 98 percent zinc and 2 percent aluminum followed by a conventional epoxy coating. The systems are compared with conventional uncoated reinforcement and conventional epoxy coated reinforcement. The results presented in this report represent the findings obtained during the first half of a 5 year study that includes longer term ASTM G 109 and field tests. In the short term tests used to date, the epoxy coatings evaluated provide superior corrosion protection to the reinforcing steel. The results also indicate that the bars will continue to perform well in the longer term, although the tests do not evaluate the effects of long term reductions in the bond between the epoxy and the reinforcing steel. The corrosion rate on the exposed regions of damaged epoxy coated reinforcement is somewhat higher than the average corrosion rate on the surface of uncoated reinforcement subjected to similar exposure conditions. The use of concrete with a reduced water cement ratio improves the corrosion performance of both conventional and epoxy coated reinforcement in uncracked concrete but has little effect in cracked concrete. Increased adhesion between the epoxy and reinforcing steel provides no significant improvement in the corrosion resistance of epoxy coated reinforcement. It appears that corrosion inhibitors in concrete and the primer coating containing microencapsulated calcium nitrite improve the corrosion resistance of the epoxy coated steel in uncracked concrete, but not in cracked concrete. The zinc coating on the multiple coated bars acts as a sacrificial barrier and provides some corrosion protection to the underlying steel in both uncracked and cracked concrete. The degree of protection, however, cannot be evaluated based on the results available to date

Design and evaluation of jointed plain concrete pavement with fiber reinforced polymer dowels ( )
2 editions published in 2009 in English and held by 199 WorldCat member libraries worldwide
"This study evaluates fiber reinforced polymer (FRP) dowel bars as load transferring devices in jointed plain concrete pavement (JPCP) under HS25 static and fatigue loads and compares their response with JPCP consisting of steel dowels. Along with laboratory and field evaluations of JPCP with FRP and steel dowels, analytical modeling of dowel response was carried out in terms of maximum bending deflection, relative deflection (RD), and bearing stress of dowels. In addition, field rehabilitation of JPCP was carried out using FRP dowels to evaluate its long-term performance"--Technical report documentation p

Magnetic-based NDE of prestressed and post-tensioned concrete members the MFL system ( Book )
5 editions published in 2000 in English and held by 198 WorldCat member libraries worldwide
This report describes all aspects of a study to develop a nondestructive evaluation (NDE) system based on the concept of magnetic flux leakage (MFL) to detect corrosion and fracture of prestressing steel in pretensioned and post-tensioned concrete bridge members. The basic methodology is based on introducing a direct-current magnetic field in close proximity of the prestressing or post-tensioning steel and monitoring the variations of the field due to loss of cross-sectional area of steel from corrosion or fracture. The mechanical and electrical components of the MFL system are described, as well as the software developed to acquire and analyze the MFL data and to control all hardware

China earthquake reconnaissance report performance of transportation structures during the May 12, 2008, M7.9 Wenchuan Earthquake ( )
3 editions published in 2011 in English and held by 196 WorldCat member libraries worldwide
"This report documents the lessons learned from damage caused in the May 12, 2008, M7.9 earthquake in Wenchuan County, China. The damage to the 14 observed bridges reminded the researchers of damage suffered during the 1971 San Fernando Earthquake in California. The bridges had few seismic details such as long seats, large shear keys, or tightly spaced transverse reinforcement. Most arch and girder bridges collapsed due to surface rupturing of the seismic faults in the Longmen-Shan thrust zone. A significant portion of roadways and bridges were pushed away or buried by landslides in the steep slopes of mountainous terrain. Damage to bridge superstructure included unseating of girders, longitudinal and transverse offset of decks, pounding at expansion joints, and shear key failure. The bearings of several girder bridges were either crushed or displaced significantly. The substructure and foundation of bridges were subjected to shear and flexural cracks, concrete spalling, stirrup rupture, excessive displacement, and loss of stability. More damage occurred in simply supported bridges than in continuous spans. Curved bridges either collapsed or suffered severe damage. Evidence of directivity effects on bridges near the earthquake epicenter was observed during the earthquake. The San Fernando earthquake significantly changed the seismic design and construction of bridges in the United States. The Wenchuan earthquake is expected to have the same significance for China's bridge engineers"--from technical documentation p
Back-calculation of layer parameters for LTPP test sections by Lev Khazanovich( )
4 editions published in 2001 in English and held by 194 WorldCat member libraries worldwide
"This report documents the results of backcalculation of layer material properties for rigid pavements included in the Long Term Pavement Performance (LTPP) program in the United States and Canada using deflection testing data. This study backcalculated the layer material properties for rigid pavements using the slab on elastic solid foundation and the slab on dense-liquid foundation procedures. The "best fit" algorithm was used after consideration of alternative methods of backcalculation. Pre-processing and post-processing utility software were developed to facilitate data handling. The backcalculation analysis was conducted for all General Pavement Studies (GPS), Special Pavement Studies (SPS), and Seasonal Monitoring Program (SMP) test sections. Data tables that include backcalculation parameters were developed for inclusion in the LTPP Information Management System (IMS). Key findings include the following: 1. The "best-fit" method was selected as the primary backcalculation method for both dense-liquid (DL) and elastic solid (ES) subgrade models. 2. Reasonable backcalculation results were obtained for the large majority of GPS, SPS, and SMP sections. Typical modulus values and ranges are provided for the PCC slab, many types of bases, and the subgrade. 3. Strong correlations were found between backcalculated parameters using DL and ES subgrade models. 4. Temperature curling during the day had a profound effect on the results of backcalculation [making it important to conduct falling weight deflectometer (FWD) basin testing early in the morning to reduce variability in backcalculated values]. 5. Poor correlation was found between backcalculated and laboratory elastic moduli of the concrete slab. 6. A bonded interface between the slab and base produced the best layer moduli for a large majority of the sections (center slab backcalculation)"--Tech. report doc. page
Informational report on lighting design for midblock crosswalks ( )
3 editions published in 2008 in English and held by 194 WorldCat member libraries worldwide
This report provides information on lighting parameters and design criteria that should be considered when installing fixed roadway lighting for midblock crosswalks. The information is based on static and dynamic experiments of driver performance with regard to the detection of pedestrians and surrogates in midblock crosswalks. Experimental condition variables included lamp type (high-pressure sodium and metal halide), vertical illuminance level, color of pedestrian clothing, position of the pedestrians and surrogates in the crosswalk, and the presence of glare. Two additional lighting systems, a Probeam luminaire and ground-installed LEDs, were also evaluated. The research found that a vertical illuminance of 20 lx in the crosswalk, measured at a height of 1.5 m (5 ft) from the road surface, provided adequate detection distances in most circumstances. Although the research was constrained to midblock placements of crosswalks, the report includes a brief discussion of considerations in lighting crosswalks colocated with intersections

Construction of field-cast ultra-high performance concrete connections ( )
2 editions published in 2012 in English and held by 191 WorldCat member libraries worldwide
Ultra-high performance concrete (UHPC) is an emerging construction material that has been demonstrated to advance the state of the art for construction of prefabricated bridge elements and systems (PBES). Specifically, UHPC allows for significant simplifications in the design of the component connections, while simultaneously affording enhanced durability and simplified construction practices. As of early 2012, 18 bridges in the United States and Canada have been constructed using field-cast UHPC connections, and this note displays two of those bridges. This TechNote provides an introduction to many of the topics that should be considered when deploying UHPC connections
