Smooth road slabs (PDG) are made of reinforced concrete. The density of concrete during production is 2200-2500 kgm3, frost resistance class is not lower than F200 (allows operation at air temperatures down to -55 ° C). The surface of the slab is smooth, without grooves and notches.
Overall dimensions depend on the manufacturer, but the following are considered standard: length 3 or 6 meters, width 1.5 m, 1.75 m, 2 m and thickness 14 or 17 cm.
The maximum load depends on the PDG brand and is 30 tons for the Н-30 PDG or 10 tons for the Н-10 PDG. Both slabs are used as permanent or temporary pavement..
