Evaluation of Overlay Tester Test Procedure to Identify Fatigue Cracking Prone Asphalt Mixtures

项目名称：	Evaluation of Overlay Tester Test Procedure to Identify Fatigue Cracking Prone Asphalt Mixtures
摘要：	The purpose of the study is to evaluate the Overlay Tester using field cores from the recently completed FHWA ALF Fatigue Cracking study. The study comprised of 10 different lanes, each produced to the same target volumetrics, while varying recycled asphalt contents, base asphalt binder grades, and the addition of warm mix asphalt technologies. Each lane was trafficked until fatigue cracking failure, and therefore, provides an excellent means to compare field and laboratory performance. In addition, FHWA did not include the Overlay Tester in any of their testing plans; thus, additional testing using the Overlay Tester would be first for the test facility's materials. It is anticipated that the proposed research study will result in a materials specification that can be used during mixture design and possible quality control/quality assurance testing to limit the fatigue cracking potential of asphalt mixtures. The proposed research study may also provide a general guidance document on the usage of recycled asphalt in new asphalt mixtures.
