This specification covers heavy vehicular paving bricks designed for use in streets, commercial driveways, aircraft taxiways, and other places where there is a high volume of heavy vehicular traffic. The bricks should be manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to firing. The high temperature heat treatment should develop sufficient fired bonds between the material particles to produce the required strength and durability. The bricks may also be shaped by extruding, molding, or pressing during manufacture and may have spacing lugs, chamfered edges, or both. The materials are classified into two types according to the intended installation and should all conform to the required values of freeze thaw resistance, abrasion resistance, skid resistance, coring, chips or cracks, and efflorescence.

1.1?This specification covers brick intended for use as a paving material in areas with a high volume of heavy vehicular traffic. The units are designed for use in such places as streets, commercial driveways, and aircraft taxiways. These units are not intended for applications covered by Specifications C410 or C902. 1.2?The requirements of this specification apply at the time of purchase. The use of results from testing of brick extracted from pavements for determining compliance with the requirements of this specification is beyond the intent of this standard. 1.3?Units 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 requirements of this specification (see Terminology C1232). 1.4?Brick may be shaped during manufacture by extruding, molding, or pressing. Brick may have spacing lugs, chamfered edges, or both. 1.5?Use of this standard and the requirements herein to evaluate and corroborate the performance of a paving unit made from other materials, or made with other forming methods, or other means of binding the materials is not covered by the scope of this standard. 1.6?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.7?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
