The instrument is designed and made as per standards GB/T4508, T0605 bitumen ductility test in the industrial standard JTJ052 and ASTM D113. It is suitable to determinate the ductility of bitumen — the length when the bitumen being stretched to crack with a certain speed under regulation condition and temperature.The unit is cm.
