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

17、all 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 specifier that the gridpaver
18、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 requirementsspecified in Tabl
19、e 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 Dimensions6.1 Length or width
20、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 representative shall
21、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 made with the samema
22、terials, concrete mix design, manufacturing process, andcuring method, conducted in accordance with Test MethodsC140 and within 12 months of production of the units.8.

A new sample shall be selected by thepurchaser from remaining units from the shipment with asimilar configuration and dimension
24、and tested at the 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 re
