Abstract
Asphalt compositions are improved by incorporating therein the reaction product of a hydrocarbyl substituted nitrogen-containing aromatic heterocyclic compound such as 2,4,6-trimethylpyridine, an aldehyde such as formaldehyde or ketone such as acetone and an amine such as a mixture of C.sub.10 -C.sub.18 aliphatic monoamides.
