Abstract |
|
Integral bridges are bridges without expansion joints between the abutment and the superstructure. Integral bridges have instead their continuous decks and girders integrated into the abutments. They are most cost effective system in terms of construction, maintenance, and longevity. The main purpose of constructing an Integral Abutment Bridge is to prevent the corrosion of structure due to water seepage through joints. The simple and rapid construction provides smooth, uninterrupted deck that is aesthetically pleasing and safer for riding. They also provide greater load distribution at bridge ends which aid in reducing damage to the abutments, especially from overweight vehicles. Properly drained approach slabs help control roadway drainage, thus preventing erosion of the abutment backfill or freeze and thaw damage resulting from saturated backfill. |
