Multifunctional Fully-automatic Asphalt Pressure Tester

Product ID:HW-SYD-0730A

The instrument is designed and made as per the Industry Standard of People’s Republic of China JTG E20-2011 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering.  It is suitable to do determination of Marshall stability, uniaxial compression test(cylinder, prismoid), bending , splitting and freeze-thaw splitting as per above standards.

 

I, Main technical characteristics

1. The instrument test tank has the cooling constant temperature function. The temperature balance function of the compressor refrigeration and heating piple control the temperature range of the tank in ( -2070), and meet the tank temperature requirement of the instrument test method.

2. The instrument adopts advanced sensor technology and microcomputer processing technology, and it has functions of setting parameters, measurement calibration, automatic test control, automatic data acquisition and real-time clock.

3. The instrument can storage 100 groups test data and test time, and it also can look over readily.  The whole procedure can be finished automatically and automatic reset.
