AI Technical Summary
Existing technologies cannot accurately simulate the adhesion between asphalt and aggregate under dynamic water pressure, and the evaluation indicators are not quantitative and are greatly affected by human factors, making it impossible to effectively distinguish the differences between asphalts with similar adhesion.
A test method and apparatus were designed to simulate the action of dynamic water pressure by clamping aggregates in a water bath and an asphalt tank, and to calculate the mass loss rate using a weighing meter, including horizontal and vertical movements, to evaluate the adhesion between asphalt and aggregates.
It enables quantitative assessment of the adhesion between asphalt and aggregates, accurately simulates the dynamic water pressure environment of actual road surfaces, reduces the influence of human factors, and improves the accuracy and differentiation of assessments.
