   Paver base is a form of aggregate used in the construction of patios and walkways whose topmost layer consists of mortarless (or "dry-laid") pavers. The first layer in the construction of such a surface is called the subgrade—this is the layer of native material underneath the intended surface. It is usually compacted and stabilized.

   Road salt contains chlorides that could migrate through the porous pavement into groundwater. Snow plow blades could catch block edges of concrete pavers or other block installations, damaging surfaces and creating potholes. Sand cannot be used for snow and ice control on porous surfaces because it will plug the pores and reduce permeability. [17]

   Roman concrete was superior to other concrete recipes (for example, those consisting of only sand and lime) [1] used by other cultures. Besides volcanic ash for making regular Roman concrete, brick dust can also be used. Besides regular Roman concrete, the Romans also invented hydraulic concrete, which they made from volcanic ash and clay. [2]
