Study on industrial parameter of SBS polymer-modified asphalt

Abstract

Abstract: The paper studied SBS polymer modified asphalt.It an alysed effect of blend time and temperature on SBS polymer modified asphalt prop erties,and the results show the effective blend time for Japanese asphalt,SLi as p halt and LAL asphalt modified with SBS polymer are espectively 3 hours,3 hours a nd 4 hours,based on temperature susceptibility?high temperature stability and l ow temperature stability of asphalt.With the increase of the blend temperature, the temperature susceptibility of SBS polymer modified asphalt is decreased,the soft point and ductility at low temperature are increased,and it shows that incr easing of blend temperature is beneficial to compatibility between SBS polymer a nd asphalt.

Key words: blend time, blend temperature, modified asphalt, performance

摘要： 通过对SBS改性沥青的研究,分析了搅拌时间和温度变化对改性沥青性能的影响,结果表明 :在综合考虑感温性、高温稳定性及低温抗裂性等指标时,搅拌温度在 180℃条件下,日本沥青、胜利沥青及兰炼沥青用SBS进行改性时其合理的搅拌时间分别为 2h,3h和 4h;随着搅拌温度的升高,改性沥青的感温性降低、软化点、低温延度增加;说明适当增加搅拌温度有利于聚合物与沥青的相容

To further study its influence mechanism and to solve the problem of limited accuracy of traditional prediction methods under multi-feature data conditions, a pavement skid resistance performance assessment model based on the fusion of Bayesian optimization algorithm (BOA) and extreme gradient boosting (XGBoost) was proposed. Firstly, specimens phalt mixtures of different gradation types were prepared. Friction data and 3D texture data of the specimen surface were respectively obtained by using a pendulum friction meter and a 3D laser scanning device. Secondly, the height, the wavelength and shape parameters were extracted to describe the texture structure, and the texture feature importance analysis was carried out to clarify the factors that significantly affected the skid resistance. Then, the optimal key parameters were improved by introducing of the model BOA-XGBoost and the prediction model of skid resistance performance was established. The research results show that compared with the comparative models, the proposed model has higher accuracy, with a correlation coefficient R2 of 0.890 6, which is 25.2%, 13.0%, and 15.1% higher than those of the comparative models, respectively. The proposed model can effectively correlate texture features with pavement skid resistance performance. [J]. Journal of Chongqing Jiaotong University(Natural Science), 2025, 44(6): 35-44.
