Simple Fatigue Test for Thin Overlays

A test to effectively characterize the cracking and fatigue potential of asphalt mixes placed as thin overlays is lacking. The proposal outlines a research study to address this shortcoming. The objective of the study is to identify and recommend a practical and suitable test (or modifications to existing tests) that can be used by state departments of transportation (DOTs) better screen all asphalt mixtures during mixture design and for quality control and assurance (QCQA) purposes. As part of the research study, it is proposed that the suitability of a variety of fatigue tests be investigated to determine their ability to efficiently discriminate and rank the fracture behavior of all asphalt mixtures used in Texas and Hawaii. Candidate tests that are best suited will be identified for further evaluation, specifically to develop test procedures and specifications for an application. An experiment is proposed to assess the influence of variations in material properties on the fracture performance of asphalt mixtures to gauge the sensitivity of the candidate tests and to develop minimum criteria for specification of quality requirements for aggregates used in asphalt mixes.
