• Abstract:
  To improve the performance of hot-mix asphalt concrete at high temperatures, crumb-rubber is typically used. Although hot-mix asphalt concrete consisting of crumb-rubber has been successfully placed and have performed well over the years, the laboratory design and preparation of specimens are sometimes problematic. The current mix design procedure (Tex- 232-F) is cumbersome and requires preparing a large number of laboratory specimens to carry out an appropriate mix design. The purpose of this research project is to identify the problems with and provide solutions to the current procedure. In addition, the mix design procedure using Superpave Gyratory Compactor is also included in this report.
