摘要
岩沥青改性沥青具有良好的抗高温、抗车辙能力,但对温度较敏感,施工中应严格控制加热温度,做好运输过程中的保温,保证摊铺、压实温度。2005年和2006年京福高速公路山东段的应用表明,岩沥青改性沥青抗车辙效果明显,值得推广和应用。
Gilsonite modified asphalt has excellent high temperature resistance, rutting resistance, but it is sensitive to temperature. It is necessary to strictly control the heating temperature in construction and to make sure the insulation, pave and compaction temperature during transportation. The application in Shandong section of Beijing-Fuzhou expressway during 2005 and 2006 shows that the effect of rutting resistance is evident, and it is helpful for popularization and application of this kind of asphalt.
