The development process included a number of phases, which are described in the report. Included in this report are the following: 1) a state-of-knowledge review for fatigue response of asphalt aggregate mixes, 2) a description of a pilot test program and its results, 3) a description of an expanded test program using the equipment and methodology selected in the pilot test program, and 4) a description of a mix analysis and design system, which can be used to mitigate fatigue cracking.
In order that considerations for fatigue distress of the asphalt concrete may be incorporated into pavement design procedures, it is necessary that definitive information on the fatigue behavior of asphalt concrete mixtures be determined. Data are presented based on a review of the literature as well as our research, which illustrate the effects of a number of mixture variables on fatigue response and include an indication of the influence of: mixture stiffness, air void content, aggregate gradation, aggregate type, asphalt content, and asphalt type.
Thirteen papers presented at the conference on [title], held in Phoenix, Arizona, December, 1994, discuss the products of the strategic highway research program, the Superpave method of mix design, and test methods for fatigue cracking and permanent deformation.

This report describes the research conducted on permanent deformation of asphalt concrete mixes as part of the SHRP Asphalt Research Program. Divided into three sections the report addresses the following: the development of a series of accelerated performance tests to measure the permanent deformation response and a constitutive relationship to define it; validation of the binder properties included in the SHRP binder specification; and the use of the test methodology in an asphalt concrete mix design and analysis system.
