This Geotechnical Special Publication contains 26 peer-reviewed papers showcasing recent developments and advancements in geotechnical and pavement engineering and offering insights into future directions for geoengineering in the 21st century.

GSP 191 covers advances in roadway and pavement maintenance and management. The papers in this volume gracefully balance theoretical analyses and practical applications. The five major topics analyzed include:

• advances in laboratory characterization of pavement materials
• forensic studies
• rehabilitation strategy selection and preventative maintenance treatments
• roadway widening
• stabilization, recycling, foamed bitumen and emulsion, granular materials   

This publication will be valuable to pavement engineers, researchers, and practitioners in providing improved road pavement infrastructure. Geotechnical professors and students, design engineers, contractors, and others involved in geotechnical engineering will also benefit.
