The use of cold-mixed, emulsified asphalt mixtures in low-volume roads has been widely accepted by highway engineers in the past few decades. A comprehensive experimental investigation has been performed in order to characterize a marginal-quality mixture prepared by mixing sand and gravel with emulsified asphalt. A mix preparation procedure has been developed that simulates the cold-mixing operation usually used in the pavement of low-volume roads either in base courses or in surface treatment. The emulsion mixture properties were evaluated by using Marshall and Hveem procedures at ambient temperature. The tensile and resilient characteristics of the mix were obtained at three different temperatures. The effects of emulsion content, curing, and vacuum saturation were investigated. The influence of adding a small amount of portland cement was also evaluated. Finally, the properties of the emulsion mixture and asphalt concrete were compared. Significant results were obtained, which provide the highway engineer with a better understanding of the integral behavior of the emulsified asphalt mixture. This may help in increasing the use of emulsified asphalt as a binding agent in the pavement of low-volume roads in a more optimal way. (Author)
