This instrument is based on the transportation industry standards of the People's Republic of China JTG E20-2011《 Test Regulations for Asphalt and Asphalt Mixture in Highway Engineering T0624-2011《 Asphalt viscosity toughness test and petrochemical industry standards SH/T0735-2003《 Designed and manufactured as required by the Asphalt Viscotrability Test Law. Applicable to T0624-2011《 Asphalt viscosity toughness test》, SH/T0735-2003《 Asphalt Viscotyleness Testing Standard stipulates the requirements to test the viscotyleness of asphalt under specific conditions to evaluate the modification effect after asphalt is added with a modifier.

1. Main technical characteristics
1、This instrument is compatible with the requirements of two test standards in the transportation industry and petrochemical industry. The tensile length can be selected from 300 mm Or 610 mm； The tensile tester runs smoothly and reliably, and has high measurement accuracy.
2、Independently developed test and testing software, which can automatically draw and print "viscosity test load" ∼Deformation curve and automatic calculation of viscotility and toughness of asphalt, for the uncommon "viscotility test load ∼Deformation curves” also allow researchers to reasonably correct the toughness tangent.
3、The test and test results calculation of this instrument can be completed by operating the laptop, which is extremely convenient to use.
4、The control panel is simple to design, and can also be easily operated and tested through the up key, down key and stop key on the panel, and the laptop automatically completes the calculation of the test results.
5、Configuration A4 Printer (optional), can automatically draw and print "viscosity test load ∼Deformation curve” and the viscotrity and toughness values ​​of asphalt.
6、The instrument has advanced design, exquisite production, exquisite appearance, simple operation, and noble temperament of high-end instruments. It is an ideal choice for related construction, supervision, scientific research units and colleges.
The biggest feature of this instrument is: using a laptop to operate and control the entire process of tests, and realize fully automatic detection of asphalt viscosity toughness.
