1) The asphalt pressure apparatus has multiple functions which fitting following standards contained in JTG E20-2011.
A. T 0709 Bituminous Mixtures Marshall Stability Test
B. T 0715 Bituminous Mixtures Bending Test
C. T 0716 Bituminous Mixtures Splitting Test
D. T 0729 Bituminous Mixtures Freeze-thaw Splitting Test
2) The test box has the function of cooling and constant temperature. The temperature of the test box is controlled within the range of (-20~70)℃ through the compressor cooling and heating tube balance function, which can meet the temperature requirements of the test box specified by the test method.
3) The asphalt pressure apparatus 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.
4) 100 sets of test data and test time can be stored inside the instrument, which can be checked at any time. All tests are completed automatically and can be automatically return.
