Process for repairing asphalt pavement

Claim 1

In a process for repairing and surfacing broken asphalt pavement which comprises heating and applying a fluid ductile asphaltic composition to a distressed pavement surface in a sufficient quantity to penetrate and fill void spaces, the improvement being said ductile asphaltic composition comprising a homogeneous blend of (1) between about 30-80 weight percent of an asphalt component selected from marginal asphalt materials having a viscosity penetration index lower than about 2.5×10 5 ; (2) between about 10-60 weight percent of a highly aromatic petroleum refinery residuum solvent component having a boiling range above about 650° F. and having a hydrogen content distribution in which the H Ar proton content is between about 30 and 50 percent, the H.sub.α proton content is at least 30 percent and the H.sub.α /H.sub.β proton ratio is above about 1.4; and (3) between about 1-20 weight percent of a polymeric component which is substantially asphalt-soluble; wherein the said asphaltic composition has a ring and ball softening point in the range between about 110°-185° F., a ductility of more than 100 centimeters at 77° F., and a penetration value in the range between about 70-300.
