STRUCTURAL PROPERTIES OF LABORATORY MIXTURES CONTAINING FOAMED ASPHALT AND MARGINAL AGGREGATES. Academic Article

abstract

• Four sands and one siliceous river gravel from various regions of Texas an were stabilized with foamed asphalt to produce laboratory test specimens. The strength, stiffness, and stability of these specimens were measured by using common laboratory testing methods. The water susceptibility, temperature susceptibility, and fatigue performance of the asphalt paving mixtures were quantified. Equivalent thicknesses were determined for these foamed-asphalt mixtures. Based on available literature, foamed asphalt appears to be an economically attractive alternative for stabilization of pavement bases and subbases. However, laboratory results obtained in the study which used marginal aggregates, suggest that foamed-asphalt mixtures have low stabilities and poor fatigue performance in comparison with conventional hot-mix paving materials.
