3.2 Tractor

A vehicle that carries all the components and tow the mixing device when working and when transferring between construction sites.

3.3 Mixing device

A device consisting of moving parts that perform in-situ processing (such as stirring or dispersing) of stabilized earth material.

Note. The mixing device usually consists of a power-driven rotor equipped with a cutter, which rotates during the mixing operation (see Appendix A, Figure A.1 ~ (Figure A.5). Another type of mixing device uses special cutters to reciprocate during mixing operations (see Figure A.6).

3.4 Variablemixerchamber
