Dr.John Harvey's Presentation on"Mechanistic Emperical"

The Caltrans Division of Research and Innovation is hosting monthly videoconferences on various topics. The presentations are designed to bring researchers and practitioners together to exchange information and transfer knowledge.

On June 28, 2007, 9:30 AM - 11:30 AM, Dr. John Harvey presented "Mechanistic Emperical"

Dr.Koohong Chung
Dr. John Harvey
Professor of Civil and Environmental Engineering at the University of California, Davis

University of California, Davis. He is Principal Investigator for the Caltrans Partnered Pavement Research Center Project operated by the University of California Pavement Research Center for research and development of a wide range of pavement technology. He is a licensed professional engineer in California. The UC Pavement Research Center operates from the Davis and Berkeley campuses

Topic Description:  Mechanistic Emperical

Current Caltrans pavement design methods are empirical (observations of pavement performance.) Caltrans is now moving towards implementation of mechanisticempirical (ME) design methods that combine pavement performance with calculations of stresses, strains and deflections in the pavement layers under the traffic loads and climate conditions. These two approaches to pavement design will be compared, and the reasons for moving to ME design will be discussed, including potential for cost savings through innovation in design and materials
