Measuring Instrument for Ductility of Asphalt,ASTM D113

Purpose:

GD-4508G Ductility Measuring Instrument 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

Technical characteristics

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 ductility of 3 pieces of samples and dragging force of 2 pieces of samples at the same time.

5. It adopts computer control techniques, so it is with high temperature controlling accuracy.

6. It has function of automatic positioning for test mold. You can make determination remotely. It is convenient.

7. It uses a large LCD to show temperature, ductility, dragging force, and other parameters clearly. The interface is friendly.

8. Equipped with a micro-printer, it can print out test data (ductility of each sample, average value of ductility, the maximum dragging force, and dragging force change curve automatically.

9. Equipped with a computer communication port, it can communicate with a computer conveniently.
