| 摘要 |
Asphaltic compositions comprising waste material are obtained by heating a mixture of solid organic waste, sulfur, and a liquefaction solvent to a temperature of 300 DEG F. to 1000 DEG F. to provide asphaltic pitch-like compositions which are useful as paving binders and coating compositions. The method for producing paving compositions is compatible with current petroleum refining technology and affords a low-cost method of waste disposal.
