1、Designation: C1319 14Standard Specification forConcrete Grid Paving Units1This standard is issued under the fixed designation C1319; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses
2、 indicates the year of last reapproval. Asuperscript epsilon () 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, and revetments.NOTE 1
3、When particular features are desired, such as weightclassification, higher compressive strength, surface texture, finish, color,or other special features, such properties should be specified separately bythe purchaser. However, local sellers should be consulted as to availabilityof units having the
4、desired features.1.2 The text of this standard references notes and footnoteswhich provide explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be consideredas requirements of the standard.1.3 The values stated in inch-pound units are to be regardedas stan

United States15.2 Units shall have a minimu
16、m specified thickness of 318in. (80 mm).5.3 At the time of delivery to the work site, the units shallconform to the physical requirements prescribed in Table 1.5.4 DurabilityDurability shall be demonstrated by provenfield performance satisfactory to the specifier that the gridpaver units have adequa
17、te durability for the intended use.5.4.1 Proven Field PerformanceSatisfactory field perfor-mance is demonstrated when units similar in composition andmade with the same manufacturing process as those to besupplied to the purchaser, maintain the physical requirementsspecified in Table 1 after three y
18、ears 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 supplied to thepurchaser.6. Permissible Variations in Dimensions6.1 Length or width of units shall no
19、t differ by more than618 in. (63.2 mm) from specified dimensions. Heights of unitsshall not differ by more than 618 in. (63.2 mm) from thespecified dimensions. Tests shall be performed as required in7.2.7. Sampling and Testing7.1 The purchaser or his authorized representative shall beaccorded proper
20、 facilities to inspect and sample the units at theplace of manufacture from lots ready for delivery.7.2 Compressive strength, absorption, density, and dimen-sional tolerances shall be based on tests of concrete grid pavingunits of any configuration or dimensions made with the samematerials, concrete
21、 mix design, manufacturing process, andcuring method, conducted in accordance with Test MethodsC140 and within 12 months of production of the units.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 cons
22、truction.9. Compliance9.1 If a sample fails to conform to the specifiedrequirements, the manufacturer shall be permitted to removeunits from 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
23、 expenseof the manufacturer. If the second sample meets the specifiedrequirements, the remaining 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
24、samplefails to meet the specified requirements.NOTE 2Unless otherwise specified in the purchase order, 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
25、; (2) if the results of the tests show that theunits conform to the specification requirements, the cost is typically borneby the purchaser.10.
