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

Physical Requirements5.1 Units shall have maximum length and width dimensionsof 24 in. by 24 in. (610 mm by
18、 610 mm).5.2 Units shall have a minimum 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 specifie
19、r that the gridpaver units have adequate 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 requirem
20、entsspecified 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 supplied to thepurchaser.6. Permissible Variations in Dimension
21、s6.1 Length or width of units shall not 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
22、representative shall beaccorded proper 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
23、 made with the samematerials, concrete 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
24、 the strength or permanenceof the construction.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 configu
