Description

Technical Field

[0001] The utility model relates to the field of asphalt ductility detection, in particular to a scraping structure for asphalt ductility detection with safety protection. Background Art

[0002] The steps of asphalt ductility detection are to mix the release agent evenly and apply it to the inner surfaces of the bottom plate of the clean and dry test mold and the two side molds, and install the test mold properly on the bottom plate of the test mold. Prepare the sample, and then carefully pour the sample into the mold slowly back and forth several times from one end to the other end of the test mold, and finally it is slightly higher than the test mold. Pay attention not to mix air bubbles during the pouring process. The specimen is cooled at room temperature for 30 min - 40 min, and then placed in a constant temperature water bath at the specified test temperature ±0.1°C. After maintaining for 30 min, take it out and use a hot spatula to scrape off the asphalt higher than the test mold to make the asphalt surface flush with the test mold surface. The scraping method of the asphalt should be from the middle of the test mold to both ends, and the surface should be scraped smoothly. In the prior art, manual scraping of asphalt with a knife is usually used, and there are often phenomena of too little or too much asphalt scraping. Moreover, since the heating temperature of the hot spatula cannot be determined, too high a temperature will cause damage to the asphalt, thus affecting the subsequent asphalt ductility test results. Secondly, when manually scraping the asphalt with a knife, the experimenter is easily scalded by the high-temperature spatula.

[0003] Therefore, a scraping structure for asphalt ductility detection with safety protection is needed to solve the above problems. Content of the Utility Model
