Refrigerated Ductility Test

The Refrigerated Ductility Test Apparatus is a high-precision laboratory instrument designed to evaluate the ductility of bituminous materials under low-temperature conditions. This test determines the elongation capacity of bitumen before it breaks, ensuring that the material remains flexible and resistant to cracking in cold climates. Bitumen with insufficient ductility can lead to brittle pavements, increasing the risk of premature failures such as cracking and surface deterioration.
