摘要: This report鈥檚 primary objective was to provide complimentary and supporting reference information for field aging of asphalt concrete in Mississippi. The primary data sets collected for this overall body of work are from full-scale constructed test sections where cores were collected over time (Volume 2), and from plant mixed asphalt containing warm mix technology that was field aged for four years or laboratory conditioned (Volume 3). Approximately 5,100 mixture specimens were tested as part of this three volume set of reports. When rounded to the nearest hundred mixture specimens, 300 were tested for Volume 1 (this report), 3,400 were tested for Volume 2, and 1,400 were tested for Volume 3. Binder testing was also performed in support of mixture testing. This report documents testing of mixtures produced with a single aggregate source to measure the interaction of binder and mixtures during aging. These mixtures showed the importance of aging within mixtures to capture environmental effects. This report also documents testing of air force base mixtures after being laboratory conditioned or after field aging in Columbus, MS. A summary table of how much field aging each laboratory conditioning protocol simulated is provided. Single aggregate source and air force base mixtures also provided information related to the suitability of indirect tensile strength and Cantabro mass loss testing for capturing intermediate temperature effects from environmental aging. All this information is intended for use within the more comprehensive volumes 2 and 3 of this report series. The information contained in this report is written so that it can be used in a standalone manner by others, or to compliment the remainder of this research effort.
