ABSTRACT The 1977 results of stake tests with low and high tar acid content creosotes (high temperature and low temperature creosotes) placed since 1952 are given. It was found that the amount of the residue with boiling temperatures higher than 355°C is correlated with the performance of the pure creosotes, irrespective of the processes used in producing the creosotes. The addition of PCP, copper naphthanate as well as 30% Synthol waxy oil increases performance when compared with pure creosotes.
