Abstract

Abstract: The flexure-tension resistant performance and flexural fatigue life of semi-rigid roadbase cement stablilized crushed stone medium beam is investigated experimentally in this paper. The influence on the stress?deformation and fatigue is comprehensively analyzed while soil engineering grid is laid at the bottom of semi-rigid base material .The results show that the Flexure-tension resistant performance and fatigue life is much more nicer than that of common semi-rigid base material

Key words: road engineering, soil engineering grid, semi-rigid roadbase material, flexure-tension resistant performance, Flexural fatigue life

摘要： 本文对铺设土工格栅与未铺设土工格栅的公路路面半刚性基层材料水泥稳定碎石中梁试件进行抗弯拉和弯曲疲劳试验研究，分析T：i：T格栅位于半刚性基层材料底面时对材料受力、变形及疲劳寿命的影响。结果表明，铺设土工格栅的半刚性基层材料的抗弯拉性能和疲劳寿命明显高于普通的半刚性基层材料。

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.
