GD-4508C Asphalt Ductility Tester is designed and made as per the
National Standard GB/T 4508 "Test Methods for Ductility of
Petroleum Asphalt", and T0605 "Asphalt Ductility Test" in the
Industry Standard JTJ052 Specification and Test Methods of Bitumen
and Bituminous Mixture for Highway Engineering.
It is suitable to determine the length of petroleum asphalt when it
is dragged to broken at certain speed under stipulated condition
and temperature. It is indicated by cm.
1. It integrates achievements of domestic and overseas design
concepts on ductility tester. It is advanced and delicate.
2. There is no thread rod, guide rail and other device in the test
trough, so it is convenient to install test sample.
3. Equipped with newly designed driving parts, it is stable and
synchronous without shake during dragging procedure. The dragging
speed is uniform and the ductility is accurate.
4. It can make determination for 3 pieces of sample at the same
5. It adopts digital temperature controller, high precision sensor
and magnetic circulation pump, so the bath can be adequately
circulated and the controlling temperature is precise.
6. The test sample holder can return back automatically. It will
take about 10 min to return back for 1.5 meter distance.
