(Specification)Standard Specification for Pedestrian and Light Traffic Paving Brick
Standard Specification for Pedestrian and Light Traffic Paving Brick
ABSTRACT
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.
SCOPE
1.1 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). The units are not intended to support heavy vehicular traffic covered by Specification C 1272 or for industrial applications covered by Specification C 410.
Heavy vehicular traffic is defined as high volumes of heavy vehicles (trucks having 3 or more axles) in Specification C 1272.
1.2 The property requirements of this specification apply at the time of purchase. The use of results from testing of brick extracted from masonry structures for determining conformance or nonconformance to the property requirements (Section 4) of this specification is beyond the scope of this specification.
1.3 Brick are manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirement of this specification (see firing, fired bond, and incipient fusion in Terminology C 43).
1.4 The brick are available in a variety of sizes, colors, and shapes. They are available in three classes according to exposure environment and three types according to type of traffic exposure.
1.5 The values stated in inch-pound units are to be regarded as the standard.
