The construction of masonry paving involves using materials such as bricks, stones, and concrete masonry units. These materials are chosen for their shape, color, strength, and resistance to abrasion and weathering. Masonry units can be installed dry on a thin layer of sand and a gravel base, or they can be embedded in mortar or asphalt on a concrete slab. For areas subjected to heavy vehicular loads, a rigid base layer of reinforced or unreinforced concrete is recommended. In contrast, pedestrian pathways often use a semi-flexible base of asphalt or bituminous concrete or a flexible base of gravel or sand. The setting bed, a layer sandwiched between the paving units and the base layer, is typically 1-2 inches thick and consists of pea gravel or finely crushed stone. Its primary function is to level irregularities in the base or in the units themselves. A modern feature in paving is the permeable paving system, designed to allow rainwater to pass through the pavement and infiltrate the underlying soil. This feature is achieved using porous materials such as pervious paving blocks or by designing spaces between conventional paving units filled with sand or vegetated soil. Such systems help reduce the burden on municipal drainage systems and contribute to groundwater replenishment.
Masonry pavings are used in pedestrian walkways, building entrances, patios, and sometimes in driveways.
It is constructed using bricks, stones, and concrete masonry units of different shapes and colors, with adequate strength and resistance to abrasion and weathering.
These paving units are laid over a settling base spread over a base layer.
The settling bed consists of a one to two inch thick layer of sand, pea gravel, or finely crushed stone that helps level the paving units.
The rigid base layer of pavements subjected to heavy vehicular loads may be made of reinforced or unreinforced concrete.
Whereas pedestrian pathways use a semi-flexible base layer made of asphalt or bituminous concrete or a flexible base layer made of gravel or sand.
For permeable paving, rainwater falling on the pavement is allowed to pass through it and infiltrate into the soil underneath it, thereby minimizing the runoff into stormwater drains.
This is ensured by spacing the units with sand or planted soil between them or using porous pavers, such as pervious concrete or open paving blocks.
