This study aims to optimize the construction of asphalt pavement performance monitoring stations to enhance interactivity between monitoring data,considering the variability of traffic loads.Firstly,a pavement sensor layout scheme was designed to monitor the mechanical response and environmental information of different structural layers in the asphalt pavement system,taking into account the functional characteristics.Additionally,a monitoring method for different response indexes was proposed.Secondly,based on engineering practical experience,the paragraph summarizes the standardized process of sensor placement and clarifies the key elements of data center construction.Finally,batch processing and analysis techniques were proposed for massive monitoring data,utilizing the collected high-frequency response data.The results demonstrate that the proposed pavement sensor layout accurately monitors dynamic stochastic loading and provides a reliable database for analyzing the interaction between loading and pavement response.To effectively improve the stability of data quality,methods such as moving average filtering and linear interpolation techniques can be employed to address issues such as baseline drift and data breakpoints in high-frequency response data.The method of setting a threshold proves to be useful in eliminating noise interference signals.
