CAEE Seminar - Case History: Ground Improvement Test Section The Ohio River Bridges, Louisville /Southern Indiana Approaches

The Civil, Architectural and Environmental Engineering Department will be hosting a seminar featuring Hayward Baker, Inc.'s, Mike Minton, P.E. The topic of the seminar will be Case History: Ground Improvement Test Section The Ohio River Bridges, Louisville /Southern Indiana Approaches.

Abstract

The Ohio River Bridges – Downtown Crossing Project consists of construction of a new cable stayed bridge that will carry northbound traffic on I-65 across the Ohio River from Louisville, KY to Jeffersonville, IN. Associated with the new main river bridge is a major redesign and realignment of the ramps and interchange junctures where I-65, I-71 and I-64 converge along with the Kentucky approaches to the downtown Ohio River bridges. Hayward Baker (HBI) was the designer and installer of the ground improvement systems required for the project. As part of HBI’s quality control program, HBI constructed a test embankment supported by ground improvement elements. The test embankment was instrumented to measure settlement, pore pressures and earth pressures. The purpose of the instrumented test embankment was to provide a full-scale validation of the performance of the ground improvement elements as well as HBI’s design and installation methodology. This presentation will discuss the results of the geotechnical investigations; predicted behavior and observations; project criteria; test embankment section, instrumentation and results; selection of production elements; and installation of production ground improvement elements.
