Abstract: An asphaltic roadway base or sub base which includes a by-product of petroleum refining units utilizing a Residuum Oil Supercritical Extraction (ROSE) process. The base course is a designed mixture of a resin-asphaltene residuum and aggregate, wherein the resin-asphaltene residuum has a penetration less than 10 at 77.degree. F. and a softening point above 150.degree. F., the resin-asphaltene residuum is present in the range of 3% to 12%, by weight of the composition, and the aggregate is present in the range of 88% to 97%, by weight of the composition.

Abstract: A composition for use as a road base or levee fill. The composition comprises catalytic cracking catalyst particles in the size range of 1 to 200 microns and a binder the type and amount of which depend on the end use. Hydrated lime is employed as the binder in road base construction while hydrated lime, portland cement, fly ash or mixtures of fly ash and portland cement can be used in levee construction. The spent catalyst particles are present in amounts of 80% to 96% and the binder is present in amounts of 4% to 20%, both percentage ranges being determined according to the dry weight of the composition.
