What is the minimum aggregate base thickness required for installing concrete pavers for streets?

The minimum aggregate base thickness required for installing concrete pavers on streets is 8 inches. This thickness is essential to provide adequate support for the pavers, ensuring that they can withstand the load from vehicular traffic. An appropriate base thickness contributes to proper drainage and reduces the risk of deformation and shifting of pavers, which can occur under heavy loads or due to freeze-thaw cycles in colder climates.

Using a base thickness of 8 inches also helps in distributing the load more evenly across the paver surface, extending the overall lifespan of the installation and maintaining surface integrity. This standard is widely recognized in paving and landscaping practices to ensure a durable and functional paving system. The choices less than 8 inches would typically not provide the necessary structural integrity for roads or heavy-weight applications.
