Research Review and Application Prospect of Road Paving Structure Design System with Perception Characteristics

To promote the intelligentization of road infrastructure and realize the intelligent perception function of road paving structure, the research progress and development trend of road paving structure design system integrating perception characteristics were reviewed. First, the connotation of road paving perception information was clarified, including road environment perception, vehicle load perception, road surface function perception, and structure response perception. On this basis, the design idea of hierarchical perception of road paving structure was proposed. Aiming at the current imperfect design of road paving perception, a preliminary construction of a road paving structure design system that integrates intelligent perception characteristics was proposed. Finally, the problems existing in the design and application of road pavement structure integration with intelligent perception characteristics were identified, and its development and application were prospected. It is found that the perception design of road paving structure should comprehensively consider factors such as road grade, regional environment, service demand, project cost and development trend, and carry out hierarchical design based on the idea of “safety first, hierarchical progression”, and integrate the characteristics of intelligent perception. The road paving structure design system should cover the perception system, material design, layout combination, perception performance retention, calculation theory and design specifications and requirements. In the road paving structure design and application process that integrates the characteristics of intelligent perception, there were problems of the design connotation unclear, the implementation standards of perception technology not uniform, the performance maintenance technology of the perception pavement structure imperfect, and the perception data processing and application not standard. In the future, it has broad application prospects in the construction of the long-term performance observation scientific network of highways, the formulation of scientific and reasonable road maintenance decisions, and the research and development of long-life pavement design methods suitable for our country.
