ASTM International Standard Specification for Pedestrian and Light Traffic Paving Brick ASTM C902-10

This specification covers brick intended for use as paving material subjected to pedestrian and light vehicular traffic. The units are designed for use in pedestrian applications and vehicular areas that are subjected to low volumes of vehicular traffic, such as residential driveways and streets and commercial driveways (passenger drop-offs). Abrasion resistance is specified by one of three types: type I - brick subjected to extensive vibration, type II - brick subjected to intermediate abrasion, and type III - brick subjected to low abrasion. The brick shall conform to the physical requirements for the class specified as prescribed. The requirements for water absorption (24-h cold) and saturation coefficient specified, shall not be required if a sample of five brick survives 15 cycles of the sulfate soundness test. The brick shall meet the requirements of either column for the applicable traffic use.
