摘要:
研究掺加水泥和消石灰对沥青胶浆性能的影响.通过测试不同替换量下掺加水泥和消石灰时沥青胶浆的高温、低温性能和施工性能,发现掺加水泥后胶浆的软化点增加,黏度降低,低温性能得到改善.但是替换量超过60%时,胶浆延度改善幅度降低,因而水泥替换量不宜超过60%;当掺加消石灰时沥青胶浆软化点和黏度显著增大,BBR试验显示低温抗裂性能劣化,但是替换量不超过20%时,对低温性能影响较小.
Abstract:

The effect of mixed cement and slaked lime on the properties of asphalt slurry was studied. By testing the high and low temperature properties and construction performance of asphalt slurry when cement and slaked lime were added under different replacement amounts, it was found that the softening point of the slurry increased, the viscosity decreased and the low temperature performance was improved after the addition of cement. However, when the replacement amount exceeds 60%, the improvement of the slurry ductility is reduced, so the cement replacement amount should not exceed 60%; When slaked lime was added, the softening point and viscosity of asphalt slurry increased significantly, and the BBR test showed that the low-temperature crack resistance deteriorated, but when the replacement amount did not exceed 20%, it had little effect on the low-temperature performance.
