摘要
沥青的性能是比较复杂的,使用新开发的稠度仪经大量试验以及与之相关的混合料车辙试验,从而更有效的评价沥青性能。45℃或60℃稠度试验以及与之相对应的车辙试验表明,以普通沥青的稠度和改性沥青回归后的稠度能比较好的反映沥青抵抗高温的能力。
The performance of the asphalt is more complicated, therefore it is necessary to research its appraisal index. The result of consistency test and rut test related through the new consistency in strument was analyzed, and more usefully the asphalt performance was appraised. The result shows that 45℃ or 60℃ consistency test and rut test show the consistency of unmodified asphalt and the regression viscosity of modified asphalt can appraises more usefully the asphalt high-temperature performance.
