Foreword
This document (prEN 1338:2010) has been prepared by Technical Committee CEN/TC 178 “Paving units
and kerbs”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1338:2003.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.

1 Scope
This European Standard specifies materials, properties, requirements and test methods for unreinforced
cement bound concrete paving blocks and complementary fittings. It is applicable to precast concrete paving
blocks and complementary fittings for pedestrian use, vehicular use and roof coverings, e.g. footpaths,
precincts, cycle tracks, car parks, roads, highways, industrial areas (including docks and harbours), aircraft
pavements, bus stations, petrol filling stations.
This standard does not deal with the tactility or visibility of blocks
Blocks with side features to provide wider joints for permeable pavements are included.
Permable blocks with large holes or voids or with an interconnected pore structure to allow water to pass
through the block to provide a porous pavement are not included.
In case of regular use of studded tyres additional requirements are sometimes needed.
This standard provides for the product marking and the evaluation of conformity of the product to this
European Standard.

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
arris
part of a block where two faces meet. It can be bevelled, rounded, chamfered, radiussed or splayed
3.2
concrete paving block
precast concrete unit used as a surfacing material that satisfies the following conditions:
 at a distance of 50 mm from any edge, any cross-section does not show a horizontal dimension less
than 50 mm;
 its overall length divided by its thickness is less than or equal to four.
NOTE These two conditions are not applicable to complementary fittings.
3.3
complementary fitting
unit, sometimes a part of a block, which is used to infill and enable an area to be completely surfaced
3.4
Permeable paving block
block complying with this standard with side features to provide wider joints for use in permeable pavements
3.5
overall length
longer side of the rectangle with the smallest area able to enclose the block excluding any spacer nibs
3.6
overall width
shorter side of the rectangle with the smallest area able to enclose the block excluding any spacer nibs
3.7
thickness
distance between the upper face and the bed face of the block
3.8
spacer nibs
small protruding profiles on a side face of a block
3.9
upper face
surface intended to be seen when in use

pass through.
4 Requirements for materials
4.1 General
Only materials with suitability established in terms of their properties and performance shall be used in the
manufacture of concrete paving blocks.
The suitability requirements of the materials used shall be given in the manufacturer’s production control
documentation.
Where, by conformity with relevant specifications, the properties and performance of materials have been
demonstrated, further testing need not be performed.
A reference scheme for materials inspection is given in annex A.
4.2 Asbestos
Asbestos, or materials containing asbestos, shall not be used.
5 Requirements for products
5.1 General
The performance requirements of concrete paving blocks are defined by classes which have associated
marking designations.
Blocks may be produced with a single concrete throughout or with different facing and backing layers.
When blocks are produced with a facing layer this shall have a minimum thickness of 4 mm over the area
declared by the manufacturer, when measured in accordance with Annex C. Isolated particles of aggregate
protruding into the facing layer shall be ignored. The facing layer shall be an integral part of the block.
A wipe shall only be carried out on a unit prior to curing, the constituents used shall be the same as in the
body of the block.
An arris described as square may be bevelled or rounded, its horizontal or vertical dimensions shall not
exceed 2,0 mm.
An arris with horizontal or vertical dimensions exceeding 2,0 mm shall be described as chamfered. Its
dimensions and tolerances shall be declared by the manufacturer.
Blocks may be produced with functional and/or decorative profiles, which shall not be included in the work
dimensions of a block.
The surface of blocks may be textured, secondary processed or treated chemically; these finishes or
treatments shall be described and decla
