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 crange between 4.5% and 5.5% depending on the body composition.

All of the 2 1/4" thick pavers, except the Parquet Tan, Peachtree Avenue, Red and Burgundy, also meet the specification requirements for heavy vehicular applications using a rigid base instead of a sand setting bed. They would be specified ASTM C1272, Type R, Application PX.

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