A 3-day Load Equivalency Workshop was organized by the Federal Highway Administration to facilitatie the effort to develop an improved system for determining load equivalency factors (LEF), and to develop a new approach to assess truck-pavement interaction. The participants identified the following key issues for future research: influence of road profiles on the dynamic forces imposed on the pavement; role of road simulators; inconsistencies in the results of tire research; integration of vehicle, tire and pavement dynamic models; need for a uniform definition of pavement response; and the need for distinct load equivalency models for different user classes. Each of these issues is discussed in this paper.
