Installation
It is essential that the pavement design, materials selected and construction practise are integrated in order to achieve the desired pavement quality and function. Successful installation depends upon many factors, including compliance to a detailed quality specification and the use of appropriate materials, plant and equipment.

The successful construction of a concrete flag paved area depends on four main operations:

• Preparation
• Detailing
• Compaction of sub-layers
• Bedding of flags

Any paving required an appropriate foundation. The underlying sub-layers below the flag surface course and laying course need to be correctly designed and prepared, to accomodate the anticipated applied loads.

Flags require bedding on a laying course to provide even support and prevent excessive local stressed being transmitted to the flag by high points in the underlying sub-layers/ For pedestrian areas, a mortar laying course is often sufficient but for areas subject to vehicular overrun, small element flags bedded on sand laying course, with sand joints are necessary. It is essential to maintain the structural integrity of the surface course of the surface course to prevent leading to deterioration of the sub-layers and subgrade.

The main elements of a typical fag paving construction are shown in the cross section below.
