摘要/Abstract

摘要： 为了解决沥青路面摊铺会产生的大量有毒气体这一问题,本文在70^#基质沥青中添加抑烟剂制备抑烟沥青,并对其性能进行分析。首先通过自制沥青烟气收集装置分析了掺加不同比例的Sasobit和纳米CaCO₃在单掺和复配时对沥青抑烟效果的影响,然后采用动态剪切试验、弯曲流变试验以及储存稳定性试验分析了Sasobit和纳米CaCO₃对沥青性能的影响。试验结果表明,在最佳复配比例下的Sasobit和纳米CaCO₃,能使沥青烟气抑制效果达到12%,能明显改善70^#基质沥青的高温性能,对储存稳定性无影响。

Abstract: A large amount of asphalt smoke is released from the asphalt pavement during the building process. The smoke not only causes discomfort to the workers and reduces the construction efficiency, but also causes serious environmental pollution. In order to reduce the emission of toxic gases generated during the construction of asphalt pavement, the smoke suppressant was added into 70^# base asphalt, so as to prepare smoke suppression asphalt, and the performance of smoke suppression asphalt was analysed. The effects of different dosages of Sasobit and nano-CaCO₃ added into asphalt with the method of alone mixing or compounding on the smoke suppresseion effect of asphalt were researched by self-made asphalt smoke collecting device. The effects of Sasobit and nano-CaCO₃ on the high temperature performance, low temperature performance, and storage stability performance of the asphalt were analyzed by the dynamic shear test, bending rheological test, and storage stability test. The test results show that Sasobit and nano-CaCO₃ in the optimal compound ratio can make the asphalt smoke reduce by 12% during the mixing process. The high temperature performance of 70^# matrix asphalt is significantly improved, but the low temperature performance of matrix asphalt is reduced. The combination of Sasobit and nano-CaCO₃ has no effect on the storage stability of matrix asphalt.

Key words: smoke suppression asphalt, smoke suppressant, smoke suppression effect, ratio optimization, performance analysis
