| 摘要： | Thermal cracked residues (TCR), a by-product of thermal cracking, has been used in the 1920s and '30s as paving material although they were ultimately proved unsatisfacory for this purpose. A conversion residue generally used as a blending component in heavy fuel oils or as a refinery fuel, was discovered to successfully blend into paving grade asphalt to provide surperior resistance to moisture-induced damage, and to provide similar hardening characteristics as conventional specification asphalt. This study compared the preliminary findings of this material with conventional ashpalt. All the tests showed that CR can be used in limited quantities with current asphalt. The data indicates a signficant improvement in asphalt properties and moisture performance for a number of conditions. |
