Integral abutment bridges are becoming widely accepted for new construction of short to medium length highway bridges of limited skew. Although they offer an economic alternative to the use of bearings, integral abutments present their own unique challeng...
During the Northridge earthquake of January 17 in Los Angeles, California, seven highway bridges suffered partial collapses and another 170 bridges suffered damage ranging from minor cracking to the slumping of abutment fills. This report contains a detai...
Highway agencies have been plagued with problems related to bridge expansion joints. The extent of the problem is such that many highway agencies cannot meet the maintenance demand. Many agencies, however, have managed to bypass the use of deck expansion ...
Three methods were tested in full-scale highway construction for their effectiveness at reducing the bump at the end of the bridge: expanded polystyrene, flowfill, and structural backfill. Vertical settlement, lateral movement, and soil pressure behind th...
Integral abutment bridges provide bridge engineers an economical design alternative to traditional bridges with expansion joints owing to the benefits, arising from elimination of expensive joints installation and reduced maintenance cost. The superstructure for integral abutment ...

The report documents and presents the results of a forty-two month study to develop load factor design procedures for highway bridge foundations. The findings of the study are presented in a new draft AASHTO Design Code and Commentary for foundations and ...
As the state of the art in bridge design is advancing toward the performance-based design, it becomes increasingly important to monitor and evaluate the long-term structural performance of bridges, including strains in critical structural members, soil pressures on the abutment back walls and footings, accelerations on the decks and ...

Scour around the foundations (piers and abutments) of a bridge due to river flow is often referred to as 'bridge scour'. Bridge scour is a problem of national scope that has dramatic impacts on the economy and safety of the traveling public. Bridge scour ...
Discussed in this paper is the implementation of a wireless sensor system for performance monitoring of bridges. The advanced wireless sensor system, developed at Clarkson University's Laboratory for Intelligent Infrastructure and Transportation Technologies (LIITT), allows for structural monitoring of bridges. A short-span ...
Currently, pile supported integral abutments are limited to locations where the depth of overburden can provide fixed support conditions. In Maine, there are often integral abutment bridges site with a shallow depth to bedrock where piles must be drilled ...
The purpose of this study was to assess various measures to provide streambank protection along the left descending bank of the North Raccoon River to curtail erosion which is endangering the east approach roadway, abutment wingwall, and deck of the Iowa ...
