净味改性沥青混合料设计及性能研究

摘要:

通过对净味改性沥青和非净味改性沥青的技术性能、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,改性沥青加入净味剂后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。

Abstract:

Compare the performance and smoke density of odorless modified asphalt and modified asphalt, analyze the performance and smoke reduction function of odorless modified asphalt, and compares the pavement performance of the two asphalt mixtures under the same mix proportion. The results show that the performance of the odorless modified asphalt and the modified asphalt are basically the same, and the smoke density rank of the modified asphalt after adding the net of taste can be reduced by more than 70.6%.The water stability, high temperature stability and low temperature cracking resistance of the two asphalt mixtures are basically the same.
