Determines the ductility of a bituminous material by measuring the distancein which a sample will elongate before breaking when two ends of a briquet specimen of the test material are pulled apart at a specified speed and temperature. Elastic Recovery is determined by pulling the briquet specimen to a specified distance at a specified speed and temperature. The briquet is then cut and the distance in which it takes for the two halves to reconnect is used to determine the elastic recovery of the test sample.
GD-4508C Ductility Testing Machine is designed and made as per national standard GB/T 4508-2010 Standard Test Method for Ductility of Bitumen and T0605-2011 Asphalt Ductility Test in JTG E20-2011 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering of People’s Republic of China. The method is applied to the GB/T 4508-2010 and T0605-2011 standards.
Determination of petroleum asphalt under the predetermined conditions and in certain temperature, at a certain speed stretch to fracture length, called petroleum asphalt ductility, expressed in cm
