Abstract

This paper documents the performance of Louisiana Superpave mixtures through laboratory mechanistic tests, mixture volumetric properties, gradation analysis, and early field performance. Five Superpave mixtures were evaluated in this study. One of them were designed for high-volume traffic (>30 million ESALs), two were designed for intermediate-volume traffic (between 3 and 30 million ESALs), and two for low-volume traffic (< 3 million ESALs). Three performance tests: the Frequency Sweep at Constant Height Test (FSCH) Repetitive Shear at Constant Height Test (RSCH) and Simple Shear at Constant Height (SSCH) test were compared to the Asphalt Pavement Analyzer (APA) rut test. The results showed that the FSCH and RSCH were effective in characterizing mixtures susceptibility to rutting.
