Title:
METHOD AND SYSTEM FOR SELECTING CHEMICAL REAGENT IN SURFACE ENERGY TEST OF ASPHALT MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/156256
Kind Code:
A1
Abstract:
A method and system for selecting a chemical reagent in a surface energy test of an asphalt material. The method comprises the following steps: selecting several different chemical reagents, and acquiring contact angle values formed by the chemical reagents and an asphalt microscope slide (S1); according to the contact angle values formed by the chemical reagents and the asphalt microscope slide, acquiring an asphalt surface energy parameter corresponding to a chemical reagent combination (S2); acquiring a coefficient of variation of the asphalt surface energy parameter corresponding to the chemical reagent combination, and selecting a range of the chemical reagent combination according to the variation coefficient (S3); and acquiring the number of abnormal values of an asphalt surface energy component in the range of the chemical reagent combination, and determining a final chemical reagent combination according to the number of abnormal values (S4). In the described method for selecting a chemical reagent in a surface energy test of an asphalt material, a chemical reagent combination type having high test data stability can be selected.
