Title:

METHOD AND SYSTEM FOR PREDICTING WATER CONTENT OF ASPHALT MIXTURE, AND DEVICE AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2023/284114

Kind Code:

A1

Abstract:

The present invention relates to a method and system for predicting water content of an asphalt mixture, and a device and a storage medium. The method comprises: on the basis of a preset composite material dielectric model, constructing an asphalt mixture dielectric model and a water-containing asphalt mixture dielectric model; on the basis of the water-containing asphalt mixture dielectric model and by using a volume relationship between components in a water-containing asphalt mixture, constructing a relationship model between a water volume and a dielectric constant of each component in the asphalt mixture; on the basis of the relationship model between the water volume and the dielectric constant of each component in the water-containing asphalt mixture, constructing an asphalt mixture water content prediction model based on dielectric properties; and acquiring a measurement parameter of an asphalt mixture to be subjected to measurement, and predicting, by using the asphalt mixture water content prediction model, water content of the asphalt mixture to be subjected to measurement. By means of the present invention, a theoretical basis for realizing the measurement of water content in asphalt pavement is provided, thereby facilitating the evaluation of a water-containing state of asphalt pavement, and preventing severe water damage to the asphalt pavement.
