Asphalt-soil stabilization

Paper 1: A laboratory study was made of the rate of drying of water and hydrocarbon volatiles from a soil-asphalt mixture and the effect on the stability and other basic properties of the compacted mixture. Paper 2: The effects were determined of selected chemical additives upon the strength and water-resistance of asphalt-cutback- stabilized soils. The effects of fatty amines and phosphorus pentoxide, in conjunction with asphalt, on soil stability were studied. The variables studied included soil type and/or plasticity additive and asphalt concentration, molding water content, curing and aging conditions, asphalt origin and hardness, cutback composition and solvent.
