Q24 INTERLOCKING BRICK/ BLOCK ROADS/ PAVINGS

113 CONVENTIONAL CONCRETE BLOCK PAVING OVERLAY:

Concrete block paving forms not only a surfacing but also a structural element to the overall
pavement construction. It is essential for the long term performance of the pavement that the total
construction be structurally designed, taking into account the site conditions, type and frequency of
vehicular loading, design life etc. For detailed guidance refer to British Standards BS 7533:Parts
1,2 and 3 ‘Concrete Block Paving – structural design of the pavement’ published by the Precast
Concrete Paving and Kerb Association, ‘The Structural Design of Heavy Duty Pavements for Ports
and other Industries’, published by the British Ports Federation and Marshalls’ technical literature.
The Marshalls’ Technical and Advisory Support Service is available from the earliest design stage
through their Regional Sales Offices. For details of the offices and the areas covered consult
Marshalls Technical literature.

x100mm

As a ‘rule of thumb guide’, 60 mm thick blocks are suitable for general duty, 80 mm thick for
applications up to and including heavy duty and 100 mm thick for extra heavy duty areas where
pavements are subject to extraordinary loadings.
The following special blocks are available to integrate into the Keyblok range. For further
information consult Marshalls’ technical literature or their Technical and Advisory Service.

Special blocks:
V-Groove Keyblok - Manufactured to order with a central V-groove or double chamfer to give the
visual appearance of a 100 x 100 mm unit when laid. Available in the full Keyblok colour range.
Pencil Edge Keyblok - Manufactured to order with slightly rounded top surface edges rather than
chamfers. This provides a smoother running surface than conventional chamfered blocks and is
suitable for areas where small wheeled trolleys are in use or in applications where minimal rolling
resistance is required. Available in the full Keyblok colour range. Guidance on the installation and
its use in heavy trafficked areas can be obtained through Marshalls' Sales Offices as above.
White Keyblok - Manufactured in 60 and 80 mm thicknesses, with special cement and aggregate
to give a uniform through-mix. White Keyblok is suitable for pavement markings in car parks, to
define parking bays or for other applications where high contrast, easily recognisable indicators
are required.
Colourtop Keyblok - Available in 60, 80 and 100 mm thicknesses and in white, black and yellow
colours. This surface coated Keyblok is designed for applications where durability and the
permanence of the colour coatings are of paramount importance. The surface finish includes a grit
dressing to enhance the durability of the coating and to give anti-slip properties. Colours comply
with BS6044: 1987 Pavement Marking Paints. Other colours are available to special order.
Colour/ finish:
Brindle / Burnt Ochre / Bracken (60mm and 80mm only) / Grey / Charcoal / Red / Buff / Marigold /
Red / White (60mm and 80mm only)

Other colours can be supplied to order. Keyblok is manufactured at factories in Scotland, the
North, Midlands, South, South West of England and Wales and consequently the colours and
texture can vary significantly due to the different aggregates and sands used. Marshalls
recommend, therefore, that blocks from different works are not mixed on the same site.

with Marshalls Keyblok Rectangular Block Paving.

Marshalls Tescina Textured Block Paving
Tescina combines the strength and load bearing capabilities of Keyblok with textural and aesthetic
properties normally only associated with high quality decorative paving. Experience has shown
that the enhanced surface texture will lead to improved pedestrian comfort and confidence,
particularly on sloping sites. Tescina's champherless profile also gives a smoother, more uniform
riding surface because block joints are much less pronounced.

Marshalls Cycleway Block Demarcation Paving:
In situations where a cycleway shares a route with a footpath, it is essential to maintain a clear line
of demarcation between the two carriageways - especially where visually impaired pedestrians are
to be considered.
Cycleway Blocks alert blind or partially-sighted pedestrians to the proximity of the cycleway by
providing an easily detectable underfoot warning. Cyclists are also able to clearly recognise the
central limit of their carriageway. Cycleway Blocks are intended for laying in-line, between footpath
and cycleway to form a "false kerb" which runs along the length of the shared route.

tanker parks or in any situation where the potential risk of contaminating spillage exists.
