| The analysis of bituminous binding materials derived from acid tars for compliance with the requirements of the state standard GOST has been carried out on the following key indicators: penetration and the ring-and-ball softening point. These indicators are found to depend on the content of sulfuric acid, sulfonic acids and the total acidity of the acid tar initial sample, as well as on the cracking process temperature. |
