摘要
通过对净味改性沥青和非净味改性沥青的技术性能及烟密度对比分析净味改性沥青的性能及净味效果,并基于相同配合比条件下对两种沥青混合料的路用性能进行对比分析。结果表明:净味改性沥青与非净味改性沥青的技术性能基本一致,加入净味剂后的改性沥青的烟密度等级可以降低70.6%以上。2种沥青混合料的水稳定性、高温性能和低温抗裂性能基本一致。
By comparing the technical performances and smoke densities of the odorless modified asphalt with the odor modified asphalt,the performance and effect of odorless modified asphalt are analyzed.Based on the same mix proportion,the pavement performances of the two asphalt mixtures are compared and analyzed.The results show that the technical performances of the odorless modified asphalt and the odor modified asphalt are basically the same,and the smoke density rank of the modified asphalt after added with the odorless agent can be reduced by more than 70.6%.The water stability,high temperature property and low temperature cracking resistance of the two asphalt mixtures are basically the same.
