Abstract

558,674. Road tars. WOODALL-DUCKHAM (1920), Ltd., and ARNOLD, E. July 23, 1942, No. 10299. [Class 22] Road tars, particularly those produced in coke-ovens and horizontal retorts, are treated to reduce the brittleness at low temperatures by admixture with products obtained in the refining of crude shale tar and consisting of crude paraffin wax, still grease or a neutral mixture of acid and alkaline sludges obtained in refining shale tar distillates.
