Abstract: Solutions of synthetic water-soluble polymers have been used for the construction of bored piles (drilled shafts) since the early 1990s. These engineered fluids are very different from conventional bentonite slurries but ...

Abstract: This paper investigates retrofitting precast, nonprestressed, channel beams (PCB) used in short-span bridges to improve beam shear strength and, consequently, beam ductility. Three retrofit approaches were investigated: ...

Abstract: This paper summarizes the evaluation of a thin-bonded epoxy overlay placed on an asphalt-wearing surface in an effort to increase skid resistance, decrease wear of the bridge deck, reduce the development of bonded snow and ...

Abstract: The lever rule method is often used to determine live load distribution factors (LDFs) in two-girder bridge systems because of the ranges of applicability implicit in the simplified equations of the AASHTO LRFD bridge ...

Abstract: A large number of cracks were observed in a bridge seal structure during an underwater inspection. The seal is 13.2  m long, 5.9  m wide, and 6.8  m deep and thus is considered mass concrete. The concrete mixture contains ...

Abstract: Synthetic polymer fluids are becoming a popular replacement for bentonite slurries to support excavations for deep foundation elements. However, the rheological properties of the polymer fluids used in excavation support ...

Abstract: Utilization of fly ash in concrete reduces the use of virgin materials and offers benefits of reduced landfill materials and

Abstract: A nationwide survey revealed 14 states having bridges comprised of precast, nonprestressed, concrete channel beams. Currently, the Arkansas State Highway and Transportation Department (AHTD) bridge inventory includes ...
