Description

Technical Field

[0002] An asphalt extensometer is an instrument for detecting the elongation of asphalt. The existing asphalt extensometer includes a water tank of the extensometer body, in which are arranged components for fixing the asphalt mold and a linear moving component for moving the other end of the asphalt mold. When using this asphalt extensometer, the user needs to apply an isolation agent on the mold base, and then soak the mold base, the mold and the asphalt sample in the mold in water. After soaking for a period of time, the mold base, the mold and the asphalt sample in the mold need to be manually fished out of the water, and then the mold and asphalt are installed on the linear moving component. The process of putting the mold into the water and taking it out requires the user to come into contact with water, and the operation is relatively complicated. Utility Model Content
