Though concrete and clay pavers are used most commonly for patios, walkways, plazas, and other pedestrian areas, they are equally suitable for vehicular traffic. Most of the time, designers, city planners, and developers initially consider segmental street paving for its aesthetic impact. They may see it as a way to suggest an upscale environment, evoke a sense of history, or create a festive atmosphere. But pavers offer some strictly practical advantages as well. When properly installed on an adequate base, they are strong enough to withstand virtually any traffic load. They require little or no maintenance. And they allow repairs to be made quickly, easily, and almost invisibly.
