Hundreds of people are killed or injured annually in the United States in accidents related to ice formation on roadways and bridge decks. In this paper, a novel embedded sensor system is proposed for the detection of black ice as well as wet, dry and frozen pavement conditions on roads, runways, and bridges. The proposed sensor works by detecting changes in electrical resistance between two sets of stainless steel poles embedded in the concrete sensor to assess surface and near-surface conditions. A preliminary decision algorithm is developed that utilizes sensor outputs indicating resistance changes and surface temperature. The sensor consists …

The design of integral abutment bridges is not explicitly addressed in the U.S. bridge design specifications. Despite the lack of a specific national design standard for such bridges, their usage has grown steadily since several states began experimenting with this type of structure in the 1980s. The primary objective of the work reported here was to understand and compare the current (2017) design criteria and parameters that are being utilized by various states for the design of jointless and integral abutment bridges. In this paper, the required information was sought by obtaining all publicly-available “bridge design manuals” that are commonly …
