ASTM C1272-22 PDF Download

The ASTM C1272-22 standard is titled "Standard Specification for Heavy Vehicular Paving Brick" and it covers the requirements for bricks used as paving materials in areas with high volumes of heavy vehicular traffic, such as streets, commercial driveways, and aircraft taxiways. The bricks should be made from clay, shale, or similar natural substances and undergo a firing process that creates strong bonds between the particles. The standard includes specifications for freeze-thaw resistance, abrasion resistance, skid resistance, coring, chips or cracks, and efflorescence.

The standard clarifies that it applies at the time of purchase and does not include testing extracted bricks from pavements for compliance. It also notes that the bricks can be shaped by extruding, molding, or pressing and may have spacing lugs, chamfered edges, or both. The scope of the standard does not cover the use of other materials, forming methods, or binding means for paving units.
