【 摘 要 】

Design of emulsified cold asphalt mixes using reclaimed asphalt pavement requires optimization of the emulsion and moisture content to achieve either maximum density or a minimum strength level of the mix, and in some cases both. Municipalities and local governments most often lack advanced testing equipment to design the cold mixes based on strength or stiffness results. This study was conducted with the objective of developing a simple mix design process for emulsion-based cold mixes using simple laboratory equipment such as proctor molds which are commonly used for optimization of moisture content for soil compaction.
