PMT360 asphalt batch mix machinery manufacturer

slightly higher than the HMA
E-WMA accordance with JTGF40-2004 specification requires separate AC-13 and AC-25 gradation and HMA mix design, and the results are shown in Table 2 and 3. Should be noted that the E-WMA fit than the design method in addition to mixing,different molding temperature Bitumen patching trucks with HMA, the rest can be seen from table 2, in the same class with the same porosity, E-WMA optimum asphalt  slightly higher than the HMA, which shows the work of the E-WMA HMA does not.massive experiments indicated E-WMA stream value larger than coincidence, continue to explore the issues to be text.
Performance Test
I optimum asphalt content of HMA and E-WMA, high temperature stability,independent engine water stability, low-temperature crack resistance, fatigue performance indicators compared to the performance of the evaluation of E-WMA.
High temperature stability
Wheel crushed length 300 mm, width 300 mm, thickness 50mm plate-like specimens, and then use The heating system the rutting test machine JTJ052-2000 "of Highway Engineering asphalt and asphalt mixture testing procedures for determination of its high temperature stability test temperature 60, round pressure of 0.7 MPa.
