Not illustrated. 1913 Excerpt: ...against the use of paraffine petroleum residuum as a fluxing agent for asphalt. This was not founded on the results of any careful investigation or tangible evidence. It arose at first from a desire to find some excuse for the poor wearing quality of some carelessly constructed asphalt pavements and from the fact that the earlier surfaces were readily attacked by water where subjected to its action for any length of time. It was claimed: That a part of the residuum of paraffine petroleum is soluble in water and that by the continued action of the latter on the oil in the asphalt cement, the cement is deteriorated. That on standing in a melted condition the petroleum oil rises to the top of the cement and can be "skimmed off like cream." That the bitumen of Trinidad and other asphalts are not completely soluble in paraffine residuum but are only mechanically mixed. The fallacies in two of these claims are readily shown. That the first is false is shown by the fact that distilled water which has been allowed to stand in a glass-stoppered bottle in contact with standard paraffine residuum for four years is as bright and clean as when first put there and contains nothing in solution.1 The second is equally wrong since a tank of asphalt cement maintained one week at a temperature of 300 F., without agitation, on cooling, was not to the slightest degree oily or greasy on the surface, which would be the case if any oil had separated like cream. The proposition that the bitumen of Trinidad and other asphalts is not completely soluble in standard paraffine petroleum residuum can be equally well disproved and it can be shown that asphaltic bitumens are as soluble in paraffine residuum as in the asphaltic oils of California. The results of some experiments i...
