Soil Mechanics and Bituminous Materials Research Laboratory. Design Considerations for Asphalt Pavements.

摘要

A study to determine the applicability of using laboratory-determined fatigue response to predict the behavior of pavement slabs is presented. Research in the permanent deformation area has been directed toward the development of equipment and procedures for testing specimens of asphalt concrete and soil in repeated loading to study their permanent deformation characteristics under representative environmental and loading conditions. Some preliminary results of tests on both types of materials are presented. A preliminary framework for incorporating permanent deformation considerations into the pavement design process is also outlined.
