Abstract

Abstract: Firstly, the impact of Sasobit on asphalt viscoity was studied; mix temperature of warm mix recycled asphalt mixturew as determined.High temperature performance, low temperature performance and water stability of the said mixture were studied when recycled asphalt mixture coten tw as 0% to 60%; the influence of recycled aspha ltm ix ture cotent on the properties of wa rm m ix recy cled aspha ltm ix turew as analyzed.The results dem onstrated tha t Sasobit co ld g rea tly reduce as pha lt v isco ity and lower them ix and copaction temperature of the asphalt.W a rm m ix recyc led asphalt m ixture could be em p loyed in d ifferent pavem ent structures due to its confo rma tion to current spec ifications

摘要： 研究了Sasobit掺入量对沥青黏度的影响,确定了温拌沥青混合料的拌和温度；试验研究了当废旧沥青混合料掺入量为0%~60%时,温拌再生沥青混合料的高温性能、低温性能及水稳定性,并与热拌沥青混合料的技术指标进行了比较；分析了废旧沥青混合料掺入量对温拌再生沥青混合料性能的影响。研究结果表明:Sasobit可显著降低沥青的黏度,从而降低沥青混合料的拌和与压实温度；温拌再生沥青混合料的各项技术指标均满足规范的要求, 可以用于各种路面结构中。

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.
