Abstract
The aim of this study is to use the solid petroleum wastes in road and building construction
purposes. To achieve this aim, the oily fraction of the waste was solvent extracted using
benzene. that was further used in making two asphaltic primers composed of, asphalt cement
of penetration grade 60/70 and blown asphalt of type 115/15 separately . For the obtained
solids the California Bearing Ratio (C.B.R.) was raised to be suitable for use as sub-grade
and base layers via using solid aggregates of size (2) and (6) separately in percentages of
20% and 50% by weight
