PAVEMENT AGGREGATE TREATING COMPOSITION

摘要

A composition for coating and treating aggregate intended for use in paving applications is a blend of high temperature coal tar pitch combined with coal tar oils resulting from distilling high temperature coke oven tar to pitch having a softening point from between 100 to 400 DEG F cube in Air. The oil blend having a distillation curve to 300 DEG C ASTM D 158 is shown in Table (I), in separate embodiments as shown in columns I and II. This blend of coal tar pitch and oils is optionally further blended with 0.10 to 15.00 % aromatic residue from fluidized catalytic cracking or thermofor catalytic cracking and thinned to the desired viscosity.
