Abstract: A paving composition formed of aggregate mixed with substantially unblown asphalt cement (neither emulsified nor cut-back) including a soluble organic-manganese compound either alone or in combination with organic-cobalt or organic-copper compounds for improved strength. The composition is employed for paving roads by conventional techniques.

Abstract: A method of stabilizing soil, such as sub-bases, bases and wear courses of roads and airport runways, sand dunes and other loose, particulate material, which includes mixing an epoxy resin ester of unsaturated fatty acids with soil, preferably at the optimum moisture content of the soil, in ratios of as little as one part of chemical to 200 parts of soil, with the amount depending on the use. Optionally, small but effective quantities of cement may be added to the composition in the range of about 2 to 20% of the weight of the soil. A soil coating or top dressing may be applied to the resultant structure if desired.
