Summary
This instrument 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 in the Industrial Standard of People’s Republic of China,Test Methods of Bitumen and Bituminous Mixture for Highway Engineering and ASTM D113 Standard Test Method for Ductility of Bituminous Materials. It is suitable to determine the distance to which it will elongate before breaking when two ends of a briquette specimen of the material are pulled apart at a specified speed and at a specified temperature，which is named as the asphalt ductility,and also it can measure the ductility of the coal tar pitch.The maximum measurement distance is less than 1500mm,the Unit:cm, and it can do bitumen ductility, force and bitumen elastic recovery capacity.
Main technical features
1. Full touch screen operation, convenient and fast.
2.32-bit ARM microcontroller control, automatically control the water bath’s temperature, automatically collect, deal with dragging and force data.
3. Novel design of stretch drive, uniform speed, accurate display of ductility and force.
4. Shield type cold heat balance pressurization cycle system, to ensure the temperature in the bath is uniform.
5. Data storage, easy to query.
6. Automatically calculate and display average ductility value, max.force, elongation deformation value at maximum force and etc.
