【Abstract】 To promote the intelligence of highway infrastructure and realize the intelligent sensing function of road pavement structure,the technical types and practical applications of road sensors are studied and explained, and the technical challenges of asphalt pavement sensor applications are analyzed. The results show that intelligent sensors play a vital role in the service performance monitoring of asphalt pavement. According to the different technical paths, road intelligent sensors are divided into non-contact, surface-contact and embedded types, which can realize continuous monitoring of target information such as road environment, road surface functional status and internal structure response. Limited by the harsh construction and working environment of asphalt mixture pavement, the sensor still faces technical problems such as inaccurate perception, unclear cooperative working mechanism, unclear structural damage behavior and difficult persistence of perception function in asphalt pavement performance monitoring. The research results can provide important reference value for promoting the application of sensor technology in intelligent monitoring of asphalt pavement.更多还原
