The DZ-98B motor grader

its modifications and complete sets (called hereinafter the motor graders) in question are intended for use in highway engineering for performing the earth-moving and grading jobs on soils of the I, II, III and IV categories. They are widely used in railway, airfield, land reclamation and hydrotechnical construction.
It is advisable to use the motor graders when performing especially high-volume power-consuming earth-works under heavy road conditions.
For example:

1) construction and overhaul of the dirt and gravel roads;
2) construction of the pit for the road foundation in the earth road bed;
3) moving of earth in the embankment;
4) levelling of the fill-up soil and grading of surface;
5) moving of the inertia materials wiith the stabilizing admixtures while mixing them in transit;
6) scarifying (ripping of soil and worn-out roadbeds);
7) grading of surface of large territories;
8) cleaning of snow-bound roads and territories.
The motor graders are available in two design modifications depending on the climatic conditions:
- conventional modification for operation in middle latitudes at the ambient air temperatures from minus 45 to plus 400 C;
- tropicalized modification for operation in the regions with tropical humid and dry climate.
