Reading task

3. Read the text carefully and do the tasks that follow:

The zone which is marked for laying the road, excavating the soil for filling the embankments, for building ancillary structures and for green plantings is called the road zone, or right–of–way. The higher the technical class of the road, the wider is the right–of–way for its construction.

Within the limits of inhabited places or agricultural lands used for especially valuable crops, the width of the road zone should be reduced to a minimum, and includes only the width strictly necessary for the road.

In separate cases, for example for building offices, for excavation of quarries for road–building materials, for planting fruit trees as protection against snowdrifts, excavation of borrow pits near the route, certain additional areas may be allocated. However, after the termination of construction works, the land which was appropriated for temporary structures, for the excavation of borrow pits and quarries, has to be leveled, and rendered suitable for further use in agriculture.

The section of a road by a vertical plane at right angels to the road centre line is called a cross–section. The road surface strip within the limits of which motor vehicles run is called a carriageway or roadway. Usually it is reinforced by means of natural or artificial stone aggregates (concrete) which form the pavements. The strips of ground adjacent to the carriageway are called the road shoulders. The shoulders render lateral support to the pavement, which is made of solid materials within the limits of the carriageway. Shoulders are used for temporary parking of vehicles, as well as for road machinery during the road overhaul or for stacking road repair materials.
