Document Type and Number:
WIPO Patent Application WO/2023/115827
Kind Code:
A1
Abstract:
Provided in the present invention is a method for detecting the segregation degree of an asphalt mixture. The detection method comprises the following steps: sorting aggregate particles with a particle size of ≥ 4.75 mm from a sample; soaking the aggregate particles in an organic solvent, and stirring same until the asphalt in the aggregate particles is completely dissolved; then extracting, drying and weighing same, and recording same as mass m1; screening and drying the weighed aggregate particles to obtain aggregate particles with a particle size of ＞ 2.36 mm, weighing same, and recording same as mass m2; and calculating to obtain a segregation degree L, wherein L = ((m1-m2)/m1)*100. In the present invention, the test method is provided from the perspective of the quantitative test of the segregation degree of an asphalt mixture, and a test basis is provided for controlling the segregation of the asphalt mixture, so that the working performance of the asphalt mixture is improved, and the quality of an asphalt concrete finished product is further ensured.
