Abstract
A novel asphaltic composition consisting of from about 2% to about 10% w/w of a hydrocracking residue which is the distillation residue obtained from a hydrocracking process of heavy crude oil in admixture with from about 98% to about 90% w/w of a conventional asphalt. These asphaltic compositions are especially useful when mixed with mineral aggregate to provide road mixes which lead to improved road construction or road paving.
