Abstract
Paving-grade asphalt compositions having improved resistance to weathering are described which are obtained by incorporating into a paving-grade asphalt either (1) the product obtained by alkylating phenol with a resin oil, i.e., a hydrocarbon fraction of medium molecular weight compounds in the C.sub.9 carbon range primarily aromatic in nature, or (2) the condensation product of formaldehyde with the alkylation product of phenol and a C.sub.4 raffinate stream consisting mainly of butene-1, butene-2 and isobutylene.
