Title:
MARSHALL COMPACTION METHOD AND SYSTEM FOR ASPHALT MIXTURE, MANUFACTURING METHOD AND SYSTEM FOR ASPHALT MIXTURE, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/045668
Kind Code:
A1
Abstract:
A Marshall compaction method and system for an asphalt mixture, a manufacturing method and system for an asphalt mixture, a device, and a medium. The compaction method comprises: obtaining dynamic response parameters of an asphalt mixture in a Marshall compaction process, the dynamic response parameters being used for representing the internal state of the asphalt mixture corresponding to the number of compactions; determining whether the change of the dynamic response parameters is stable; and if yes, determining the corresponding number of compactions when the change of the dynamic response parameters is stable to be a target number of compactions. According to the compaction method, the dynamic response parameters of the asphalt mixture are obtained, and the target number of compactions is determined when the change of the dynamic response parameters is stable, so that the number of compactions is automatically and intelligently determined; moreover, the change of the dynamic response parameters directly reflects the internal compaction state of the asphalt mixture, so that the accuracy of determining the number of compactions is improved, and the situation that coarse aggregate is crushed due to overpressure or the porosity does not meet the requirement due to underpressure is avoided.
