Boral Pavers – ASTM Specifications


ASTM C902-09: Pedestrian and Light Traffic Paving Brick

All Boral® Clay Pavers meet or exceed the requirements under ASTM Standard C902: Pedestrian and Light Traffic Paving Brick, Class SX Type I.

  • COMPRESSIVE STRENGTH
    The standard requires an average compressive strength of at least 8,000 psi. Boral® pavers range between 13,000 and 21,000 psi depending on the body composition.

  • ABSORPTION
    The standard requires an average cold water absorption no higher than 8.0%. Boral® pavers range between 3.7% and 7.0% depending on the body composition.

  • ABRASION INDEX
    The standard requires an average abrasion index no higher than 0.11. Boral® pavers range between 0.01 and 0.05 depending on the body composition.

  • SATURATION COEFFICIENT (C/B)
    The standard requires an average water saturation coefficient no higher than 0.78. Boral® pavers range between 0.53 and 0.76 depending on the body composition.



ASTM C1272-07: Heavy Vehicular Paving Brick

Boral® 2 3/4" thick heavy vehicular pavers meet or exceed the requirements under ASTM standard C1272, Type F, Application PX. Following are the differences between C902-09 and C1272-07:

  • COMPRESSIVE STRENGTH
    The HV standard requires an average compressive strength of at least 10,000 psi. Current production Boral® HV pavers are over 13,000 psi.

  • BREAKING LOAD
    The HV standard requires an average minimum breaking load of 475 pounds. Boral® HV pavers are rated over 1,600 pounds. Breaking load signifies the maximum stress required to break the paver in half when subjected to three-point loading.

  • ABSORPTION
    The HV standard requires an average cold water absorption no higher than 6.0%. Boral® HV pavers range between 4.5% and 5.5% depending on the body composition.


In situations where 2 1/4" pavers are installed over a concrete or asphalt base, they can support heavy vehicular applications when specified as ASTM C1272, Type R, Application PX. The type "R" refers to the rigid base (concrete or asphalt) as opposed to the normal flexible, compacted aggregate base.

All of the Antique edge finish products comply with Application PA (not Application PX) for Maximum Permissible Extent of Chippage from Edges and Corners.
