Dimensions road plates according to GOST , labeling and tips on choosing

In fact, road plates are an alternative to such types of coatings, as asphalt or tiles.They are designed for installation on large areas that are subject to significant loads.Do not confuse them with paving slabs, some of the species which though different considerable dimensions (up to 6 x 2 m), but is clearly inferior to the road at full load, since it is not designed for the weight of heavy equipment.

The latter can withstand the weight of 10 tonnes or more (usually up to 30) and have been used not only in industrial construction (highways, access roads to the facilities, airports, etc.).There is demand for them and "privateers" who use them for arrangement of branches from roads (Proselkov), leading to the suburban area, private parking lots and a variety of sites where the load on the foundation is of great importance, as well as, for example, embankments onthe banks of reservoirs.

dimensions specified standard, are expressed in "mm".Since the range is quite significant, we present only the size limits.It should be remembered that not all manufacturers adhere to them, as each of them has the right to develop their own technical specifications for products not reaching at odds with the requirements of GOST.Therefore, when buying slabs concrete numerical values ​​should be specified at the point of sale.

• length - from 1 750 to 6 000.
• width - from 1 000 to 3 750.
• thickness - from 140 to 195.

Specificity production road plates determines the appropriateness of the use of a particular type in a specific order.Therefore, only the information about their size is not enough.What else do you need to know?

Marking

plates are divided into "tense" and "Free of tension reinforcement."Their operation is possible in a temperature range up to -40 0C (of course, subject to stacking technology).They

abbreviated PD (Plate Road) and PA (airfield).All other numbers and letters are deciphered as:

• H - hard.
• F - corrugated.
• P - coating.

figure in the first position defines the type of road slabs: 1P - for permanent facilities, 2P - for temporary placement.

first two numbers behind the letter symbols denote the linear dimensions in the "dm" (length and width).Third - maximum load (in tons).

in form and execution

first position in the notation:

• P - a rectangular pattern.

remaining positions:

• D - half (diagonal axis) product hexagonal configuration.
• P - axial transverse half of the sample.
• B - 1 combined board.
• BB - with two.
• W - hexagonal.
• T - trapezoidal.

remains to add that the road plates may or metal staples or special holes (lug) for capturing a lifting mechanism.
