ASTM C1319-23a

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: C1319 − 23 C1319 − 23a
Standard Specification for
Concrete Grid Paving Units
This standard is issued under the fixed designation C1319; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification covers the requirements for concrete grid paving units for vehicular trafficways, parking areas, soil
stabilization, and revetments.
NOTE 1—When particular features are desired, such as weight classification, higher compressive strength, surface texture, finish, color, or other special
features, such properties should be specified separately by the purchaser. However, local sellers should be consulted as to availability of units having the
desired features.
1.2 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered as requirements of the standard.
1.3 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.
1.4 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.

3. Terminology
3.1 Terminology defined in Terminology C1232 shall apply for this specification.
4. Materials
4.1 Cementitious Materials—Materials Cementitious materials shall conform to the following applicable specifications:
4.1.1 Portland Cement—Specification C150/C150M.
4.1.2 Modified Portland Cement—Portland cement conforming to Specification C150/C150M, modified as follows:
(1) Limestone—If calcium carbonate is added to the cement, the CaCO content shall not be less than 85 %.
(2) Limitation on Insoluble Residue—1.5 %.
(3) Limitation on Air Content of Mortar—Volume percent, 22 % max.
(4) Limitation on Loss on Ignition—7 %.
4.1.3 Blended Hydraulic Cements—Specification C595/C595M.
4.1.4 Hydraulic Cement—Specification C1157/C1157M.
4.1.5 Pozzolans—Specification C618.
4.1.6 Slag Cements—Specification C989/C989M.
4.1.7 Silica Fume—Specification C1240.
4.2 Aggregates—Aggregates shall conform to the following specifications, except for the grading requirements:
4.2.1 Normal Weight Aggregates—Specification C33/C33M.
4.2.2 Lightweight Aggregates—Specification C331/C331M.
NOTE 2—The grading requirements of Specifications C33/C33M and C331/C331M may not be suitable for concrete grid paving unit production. Because
of this, producers are allowed to modify grading to meet their needs and the requirements of this specification.
4.3 Pigments for Integrally Colored Concrete—Specification C979/C979M.
4.4 Other Constituents—Air-entraining agents, integral water repellents, and other constituents, shall be previously established as
suitable for use in concrete grid paving units and shall conform to applicable ASTM standards, or they shall be shown by test or
experience satisfactory to the specifier and not to be detrimental to the durability of the concrete grid paving unit or any material
customarily used in grid paving construction.
5. Physical Requirements
5.1 Units shall have maximum length and width dimensions of 24 in. by 24 in. (610 mm by 610 mm).
