It is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. Generally, before laying asphalt in highway construction, construction workers need to test the elongation of asphalt.

[0003] Announcement No. (CN220231318U) discloses a low-temperature asphalt elongation tester, which starts two electric push rods installed on any side of the guide rail or starts two electric push rods at the same time to pull the two movable seats outward, and drives the asphalt constrained inside it to stretch outward through the table plate and the clamp constrained on the outside of the guide column, and uses two distance measuring components set in the base to detect the data when the current asphalt breaks.
