PHASE II REPORT - Caltrans

For the system M2 previously identified as a good mixing system, with Moderate (MV)
consistency, the mixing torque was (8 to 9 N-cm). The mix time was close to 7 minutes.
However, mix M2 never reached the maximum spread torque of (12 N-cm) before 14 minutes.
The system stiffened only after mixing ceased. The trace of mix M2 is shown in Figure 4.15.
Table 4.5 shows the summary of the ranges in torque for the three different systems with
Soupy, Stiff, and Moderate consistencies.
