Abstract

Abstract: In order to realize thereal-time detection ofcompaction degree of road surface, by analyzing the vibration compaction model, it was concluded that the compaction quality could be characterized by collecting and analyzing the variation law of the vibration wheel acceleration signal. The vibration acceleration signal was measured by the built-in signal acquisition system, and the linear relationship between the vibration acceleration and the actual compaction degree was obtained by linear fitting after signal conversion, amplification and filtering.Andby using LabView, the real-time detection system of compaction degree was established, in whichthe results were presented in the computers test software to achieve real-time detection of road surface compaction degree. The feasibility of theproposed method and the reliability of the real-time detection system are verified by engineering experiments, which provides a valuable reference for the research of compaction detection.

Key words: road engineering, real-time detection, ICP acceleration sensor, compaction degree

摘要： 为实现路面压实度的实时检测，通过分析振动压实模型，得出可通过采集并分析振动轮加速度信号变化规律来表征压实质量。利用搭建的信号采集系统测取振动加速度信号，并对其进行信号转换、放大、滤波处理后通过线性拟合得到振动加速度与实际压实度的线性关系，并利用LabView建立压实度实时检测系统，将结果呈现在计算机的测试软件中，从而实现路面压实度的实时检测。通过工程试验验证了该方法的可行性以及实时检测系统的可靠性，为压实度检测方面的研究提供有价值的参考。

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.
