中文摘要:
      为推广酸性骨料在水工沥青混凝土面板中的应用,研究了不同酸性骨料与沥青黏附性增加方案对沥青混凝土面板关键性能的影响,利用变异系数TOPSIS法综合评价酸性骨料与沥青最优增黏方案。结果表明:5种增黏方案均不同程度地提高了花岗岩骨料沥青混凝土的抗水损性能,水稳定系数、斜坡流淌值均满足规范限值;分析水损害对沥青混凝土各项性能的影响,抗压强度对水损害的敏感性最低,弯拉应变、斜坡流淌值敏感性最高。变异系数TOPSIS法综合评价结果为石灰岩沥青混凝土综合性能最优;添加抗剥落剂可使花岗岩骨料沥青混凝土的抗水损性提高18%~25%,其增加骨料与沥青之间黏附性的效果最优,但添加非胺类抗剥落剂的沥青混凝土变形较大,后续研究酸性骨料在沥青混凝土面板中的应用时,应重点关注其变形性能。
英文摘要:
      To promote the application of acid aggregates in hydraulic asphalt concrete panels, the effects of different acid aggregates and asphalt viscosity enhancement schemes on the key properties of asphalt concrete panels were studied, and the optimal acid aggregate and asphalt viscosity enhancement scheme were evaluated comprehensively using the variation coefficient TOPSIS method. The results showed that all five different viscosity enhancement schemes improved the water damage resistance of the granite asphalt concrete to different degrees, and the water stability coefficient and slope flow value all met the specification limits. According to the analysis of the effect of water damage on various properties of asphalt concrete, the compressive strength was the least sensitive to water damage, whereas the flexural strain and slope flow value were the most sensitive. Variation coefficient TOPSIS comprehensive evaluation results showed that limestone asphalt concrete had the optimal comprehensive performance; the addition of anti-spalling agent could increase the resistance of granite asphalt concrete to water damage by 18%~25% which was optimal for increasing the adhesion between the aggregate and the asphalt, but non-amine anti-spalling agent could lead to a larger deformation of the asphalt concrete. Therefore, the subsequent study of the application of acid aggregates in asphalt concrete panels should focus on its deformation performance.
