【Basic Knowledge Activity】In the petrochemical industry, how is the ductility index expressed as part of the \"basic knowledge\"?

This post was last edited by Adventure Wang on 2016-3-6 at 17:08. How is the elongation index expressed? Elongation is a quality parameter of asphalt. Previously known as elongation, it refers to the length to which an asphalt sample is stretched in a device at a rate of 5 cm per minute at 25°C until it breaks; this length is expressed in centimeters. The greater the elongation, the better the quality of the asphalt.

Ductility: It is determined using a ductility tester. An asphalt sample is shaped into an 8-shaped standard mold, and the elongation length at the point of fracture is measured at a specified tensile speed (5 cm/min) and specified temperature (25°C), expressed in cm. A higher ductility value indicates better plasticity.
The ductility test involves forming asphalt into an 8-shaped standard specimen; as required, it is stretched at a rate of 5 cm per minute (or 1 cm per minute at low temperatures) until it breaks, and the length at that point in centimeters represents the ductility. Ductility, as an indicator of the low-temperature crack resistance of road asphalt, is an important parameter for assessing the plasticity of asphalt; the greater the ductility, the better the plasticity of the asphalt.
It is determined using a ductility tester: the asphalt sample is placed in an 8-shaped standard mold, and the elongation length at the point of rupture under a specified tensile speed and at a specified temperature is measured in cm. The higher the ductility value, the better the plasticity.

A higher ductility value indicates better plasticity.
It is generally used to characterize asphalt; a standard 8-shaped specimen is pulled at a speed of 50 mm/min at 25 degrees or 15 degrees, and the length at the point of breakage is measured in cm
