PAVING STONES USED FOR COVERING IN ACCORDANCE WITH O NORM B3180
Usage:
For shaping squares, pedestrian zones, parks, draining, edge-marking stripes, ditch coverings, garage entrances, front square shaping, roads leading to home entrances, all types of highly-loaded transport areas, double small paving stones and also used for covering of gutters and big channels.

Processing of stones used for pavement covering:
Split, the front areas must be almost with the lower area, the side areas at a are acceptable according to the follow-right-squared and if possible in parallel right angle to the front area, deviations ing grading of classes.
First Class from HI to H4:
The sizes of the different stones must be within the specified limit values. Maximum 10 % of the total number to be delivered as the so called “semi-stones” (width less than the limit size, the lower limit, equal to half the width of the stone; stones with front trapezium-shaped area can be delivered up to maximum 15% of the total number.
The lower surface can be less bigger than the upper one (up to a correlation: 3:5). The split surfaces must be even, the differences between bulges and hollows to be 7 mm max. The colour and the structure must be unified.
Categories (classes) II (H1 to H3):
The sizes of the different pavement stones must be within the limit values. A maximum of 15% of the total number can be as the so called “semi-stones” (width less than the limit value, the lower limit equal to half the width of the stone).
A maximum of 25% of the total number can be stones with trapezium-shaped upper surface. The lower surface can be less bigger than the upper one (up to a Correlation of 3 : 5). The split surfaces must be even if possible, with no differences between the heights of bulges and hollows- max. 10mm.
Differences in colour and structure are allowed. For type H5 there isn’t an established differentiation between the classes, so the sizes from Table 4 must be observed. The side surfaces can be at a lower angle of a 2cm max. The split surfaces even if possible, with differences between the heights of bulges and hollows 7 mm max.
Differences in colour and structure are allowed.
