This Geotechnical Special Publication contains 12 technical papers that address the role of geotechnical engineering in the design and construction of deep foundations, earth retaining structures, and pavements. Presented at the 13th Great Lakes Geotechnical and Geoenvironmental Conference (GLGGC) held in Milwaukee, Wisconsin, May 13, 2005, several of the papers focus on the Marquette Interchange Project, a multi-million dollar reconstruction of transportation in the heart of downtown Milwaukee. The conference itself was a forum for discussion of the latest advances in geotechnical engineering applications for transportation infrastructure including earth retaining structures, deep foundations, and geotechnical engineering. This book will be beneficial to geotechnical and pavement engineers and professionals.
