The green surface is flush with the test surface. The scraping method of the asphalt should be scraped to the both ends from the middle of the test die, and the surface should be smoothed. The test piece was then placed in the extender sink for 60 minutes along with the bottom plate.

5. Place the holes at both ends of the test die on the metal posts fixed on the slide and the groove end, and remove the side mold.

6. Start the extensometer test, the instrument begins to stretch at a set constant rate, and the tensile condition of the test piece is visually observed. In the experiment, if the asphalt filaments are found floating on the water surface or sinking on the water surface, alcohol or salt should be added to the water, and the density of the water should be adjusted to be close to the sample and then retested.

7. When the time is broken, press the “Memory” button to record the ductility value of the test piece. When the three test pieces are pulled off and the memory has been memorized, the test ends normally. Under normal conditions, the specimen should be tapered when it is extended, and the actual section is close to zero when it is broken. If this result is not available, it should be noted in the report.
