Abstract:
1. An asphalt composition, comprising: an asphalt having a T10 boiling point of at least 900° F. (482° C.); and from 0.25 wt % to 2.0 wt % of a cracking resistance additive, the cracking resistance additive comprising at least one of a polyalphaolefin, an alkylated aromatic based on an aromatic having two or more fused aromatic rings and an average alkyl chain length of at least 10 carbons, or an ester, the boiling point of the cracking resistance additive being at least 140° C., and the melting point of the cracking resistance additive being at least 5° C. less than a low temperature performance grade for the asphalt, the low temperature performance grade being a low temperature performance grade for a paving asphalt.
