1、Designation: C 1319 01 (Reapproved 2006)Standard Specification forConcrete Grid Paving Units1This standard is issued under the fixed designation C 1319; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A n
2、umber in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers the requirements for concretegrid paving units for vehicular trafficways, parking areas, soilstabilization,
3、and revetments. Maximum dimensions are 24long by 24 in. wide (610 by 610 mm), with a minimumnominal thickness of 318 in. (80 mm).NOTE 1When particular features are desired, such as weight classifi-cation, higher compressive strength, surface texture, finish, color, or otherspecial features, such pro
4、perties should be specified separately by thepurchaser. However, local sellers should be consulted as to availability ofunits having the desired features.1.2 The text of this standard references notes and footnoteswhich provide explanatory material. These notes and footnotes(excluding those in table
5、s and figures) shall not be consideredas requirements of the standard.1.3 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.2. Referenced Documents2.1 ASTM Standards:2C33 Specification for Concrete AggregatesC 140 Test Me

17、upplied to the purchaser, maintain the physical requirementsspecified in Table 1 after three years of use. The units used asthe basis for proven field performance shall have been exposedto the same general type of environment, temperature range,and traffic volume as is expected for the units supplie
18、d to thepurchaser.6. Permissible Variations in Dimensions6.1 Length or width of units shall not differ by more than618 in. (63.2 mm) from approved samples. Heights of unitsshall not differ by more than 618 in. (63.2 mm) from thespecified standard dimensions. Tests shall be performed asrequired in 7.
19、2.7. Sampling and Testing7.1 The purchaser or his authorized representative shall beaccorded proper facilities to inspect and sample the units at theplace of manufacture from lots ready for delivery.7.2 Sample and test units in accordance with Test MethodsC 140, except that the coupon method for det
20、ermining com-pressive strength shall not be used.8. Visual Inspection8.1 Units shall be free of defects that interfere with theproper placing of the unit or impair the strength or permanenceof the construction.9. Compliance9.1 If a sample fails to conform to the specified require-ments, the manufact
21、urer shall be permitted to remove unitsfrom the shipment. A new sample shall be selected by thepurchaser from remaining units from the shipment with asimilar configuration and dimension and tested at the expenseof the manufacturer. If the second sample meets the specifiedrequirements, the remaining
22、portion of the shipment repre-sented by the sample meets the specified requirements. If thesecond sample fails to meet the specified requirements, theremaining portion of the shipment represented by the samplefails to meet the specified requirements.NOTE 2Unless otherwise specified in the purchase o
23、rder, the costs oftests is typically borne as follows: (1) if the results of the tests show thatthe units do not conform to the requirements of this specification the costis typically borne by the seller; ( 2) if the results of the tests show that theunits conform to the specification requirements,
24、the cost is typically borneby the purchaser.10. Keywords10.1 concrete grid paving units; revetments; soil stabiliza-tion; vehicular trafficwaysSUMMARY OF CHANGESCommittee C15 has identified the location of selected changes to this standard since C 131999 was publishedin the 2001 Annual Book of ASTM
25、Standards, Vol 04.05.(1) In Section 4 on Materials, Specification C 1157 was movedfrom Paragraph 4.1.3 to its own paragraph and identified ashydraulic cement rather than blended cement.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any i
26、tem mentionedin this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.This standard is subject to revision at any time by the responsible technical co
27、mmittee and must be reviewed every five years andif not revised, either reapproved or withdrawn. Your comments are invited either for revision of this standard or for additional standardsand should be addressed to ASTM International Headquarters. Your comments will receive careful consideration at a
