This report contains the causes and long-term solutions to the bumps at bridge/approach slab and/or approach slab/pavement interface. A research was conducted on both structural and geotechnical aspects of an approach slab.
A 3-D finite element analysis using ALGOR was performed to find the stresses and deflections for different slab lengths under HL-93 truck loading conditions. Internal moments and applied moments for seven different State Department of Transportation (DOTs) were determined and compared using MathCAD. Laboratory testing was also performed on soil samples for bridges with bumps and without significant bumps around the Youngstown area.
Several superstructure design methodologies have been developed for low volume road bridges by the Iowa State University Bridge Engineering Center. Ho...
Experimental results and analyses are given in this report on bridge abutment scour in compound channels. Experiments were conducted in a laboratory f...
