The stabilizers fitted with water and bitumen emulsion and dosing equipment. The miller, working weight 20 tons, engine power 300 kW, working width 2.50 m and maximum working depth 400 mm, has a combined buckle and back axle steering, all-wheel drive, hydrostatic operating, rotor drive and automatic performance control. The rotor has 210 milling chisels and rotates opposite to the working direction. The number of rotations can be set in 11 levels between 100 and 170 rotations [min.sup.-1] and/or set according to the requirements of the construction. The construction of the rotor cover with a variable rear hatch allows thorough mixing of the ground, binder and water components and even surfacing of the stabilized layer. The bitumen emulsion equipment with the bitumen pump, spraying beam and special nozzles for the spread of the bitumen emulsion has an easy to use manual dosing system for the control of the spray content. The nozzles can be dually controlled so that for overlapping and construction on the shoulders, the working width can be varied. A separate water-spraying beam with speed independent dosing system enables optimal moisture content for the base course material. A bitumen emulsion tank wagon, 10000 L, in front of the ground stabilizer and a water tank wagon, 7000 L, behind it supply the stabilizer with binder and water.
For the main compaction of the stabilized layer two 19 tons roller trains used, which guaranteed secure and thorough compaction of the bitumen emulsion-cement-ground mixture. The roller trains were equipped with the measuring system for controlling the compaction level, which carried out a measurement approximately every 40 mm.
