    en.wikipedia.org/wiki/Pavers_(flooring)

    Concrete paver blocks laid in a circular pattern Concrete paver blocks in a rectangular pattern. A paver is a paving stone, sett, tile, [1] brick [2] or brick-like piece of concrete commonly used as exterior flooring. They are generally placed on top of a foundation which is made of layers of compacted stone and sand.

    en.wikipedia.org/wiki/Brick

    Concrete bricks are available in many colours and as an engineering brick made with sulfate-resisting Portland cement or equivalent. When made with adequate amount of cement they are suitable for harsh environments such as wet conditions and retaining walls. They are made to standards BS 6073, EN 771-3 or ASTM C55. Concrete bricks contract or ...

    An asphalt concrete surface will generally be constructed for high-volume primary highways having an average annual daily traffic load greater than 1,200 vehicles per day. [19] Advantages of asphalt roadways include relatively low noise, relatively low cost compared with other paving methods, and perceived ease of repair.

    Stronger and less porous engineering bricks (UK Class A) are usually blue due to the higher firing temperature [3] whilst class B bricks are usually red. Class A bricks have a strength of 125 N/mm 2 (18,100 lb f /sq in) and water absorption of less than 4.5%; Class B bricks have a strength greater than 75 N/mm 2 (10,900 lb f /sq in) and water ...

    en.wikipedia.org/wiki/Permeable_paving

    Permeable paving systems, specifically pervious concrete pavers, have shown significant cost benefits after a Life Cycle Assessment was performed, as the reduction in total weight of material needed for each unit is reduced by nature of the porous design. [21]

    Strengths might exceed the ASTM standard for concrete blocks (1900 psi) in some instances. In India, the observed compressive strength and flexural strength of CSEB at 28 days of aging with 9% cement stabilization has been observed to be 3.2 MPa (464 psi) and 1 MPa (145 psi) respectively.
