SYD-4508D Asphalt Elongation TesterDetailed product description：

The SYD-4508D Asphalt Ductility Tester is designed according to the requirements specified in the Chinese standard GB/T4508 "Determination of Ductility of Petroleum Asphalt" and the Chinese industry standard JTJ052 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering", specifically T0605 "Asphalt Ductility Test". It is suitable for measuring the length of petroleum asphalt when it is stretched to fracture at a certain speed under specified conditions and temperature using the methods specified in GB/T4508 or JTJ052-T0605 standards, expressed in centimeters.

1、 Main technical features
1. Adopting a humanized design concept, there are no screws, guide rails, or other devices in the test slot, making sample installation extremely convenient with a maximum tensile length of 2.0 meters.
2. Innovative transmission design, smooth and synchronized stretching process, uniform speed, no shaking, and precise elongation display.
3. Configure three sets of test molds for ductility testing, which are made of copper material and have specifications and dimensions that meet the requirements of the standard.
