摘要：

The dependence of the penetration and the softening point of asphalts produced from acid sludge on the concentration of sulfuric and sulfonic acids that were present in the sludge, as well as on the total acidity of the initial sample, was studied. It was found that the asphalt viscosity decreases with a decrease in the concentration of sulfur-containing acids. The dependence of the asphalt softening point and on the acidity of the feedstock sludge is a logarithmic function, and the penetration is related to this parameter by a power law.
