ABSTRACT:
A shale oil modifier is made of a crude shale oil dehydrogenated sufficiently to attain a viscosity of between about 1200-1800 poise at 60.degree. C. The crude shale oil has sufficient basic nitrogen content so that the dehydrogenated crude shale oil exhibits non-Newtonian properties when mixed with asphalt cements. Preferably, the basic nitrogen content is about 2%-2.5% by weight. The shale oil modifier is made by a process which includes providing a crude shale oil and subjecting the crude shale oil to a two stage distillation followed by a vacuum distillation and collecting the residual fraction. The residual fraction is dehydrogenated with air until a select viscosity, preferably between about 1200-1800 poise at 60.degree. C. is obtained.
