In a project where both aesthetic and performance standards were most demanding, flexible clay-brick pavements have been installed. This installation, at St Peter Port, Guernsey, is possibly a world first in the context of a working port.
The clay pavers have been used to form the pavement wearing surface for an access road and berths for trailers, containers and shipping. The original 30 year-old surface of macadam-patched reinforced concrete pavement was re-profiled and overlaid with 100mm macadam and a bedding course of Category 1 sand laid, which is essential for the satisfactory performance of heavily trafficked flexible pavements.
Typically, forty 12m-containers a day are handled, using a 35 tonne-capacity front-lift truck. The pavement surface is resistant to the high compressive forces of containers stacked up to five high. The inert surface provided by the clay resists contamination by oils, acids, sea and de-icing salts. Moreover, it is claimed that 'tyre scrub' from heavy vehicles helps keep the pavement surface clean.
More than 6500m2 of 210 x 105 x 65mm-thick pavers were laid in total. There is little doubt that St Peter Port can now claim to be one of the most attractive ports in the country, with surfaces combining good looks with good performance.
