Geometric imperfections in in-situ concrete highway bridges
Geometric imperfections are inevitable in the construction of any highway bridge. Dimentional variations of in-situ concrete members, the flatness of nominally vertical, plane in-situ concrete walls, the flatness of in-situ concrete bridge decks and the cover to reinforcement have been measured in a few recently completed highway bridges. Current specification requirements for tolerance for the…
Concrete Pavement Backcalculation Results from Field Studies
Deflection testing and backcalculation have been conducted on all types of concrete highway and airfield pavements for many years. Backcalculation of the in situ slab elastic modulus and the effective k-value or elastic solid subgrade modulus (beneath the slab) from deflection basins was first proposed by Westergaard in 1925 and actually conducted in the 1930s. Over the past decade, backcalcula…
