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. Maxim

3、um 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 properties should be spe

Physical Requiremen

16、ts5.1 At the time of delivery to the work site, the units shallconform to the physical requirements prescribed in Table 1.5.2 DurabilityDurability shall be demonstrated by provenfield performance satisfactory to the specifier that the gridpaver units have adequate durability for the intended use.5.2

17、.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 years of use. The units used asthe basi

18、s 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 not differ by more than618 in. (63.2 mm)

19、 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 7.2.7. Sampling and Testing7.1 The purchaser or his authorized representative shall beaccorded proper facilities to inspect and sample

20、 the units at theplace of manufacture from lots ready for delivery.7.2 Sample and test units in accordance with Test MethodsC140, except that the coupon method for determining com-pressive strength shall not be used.8. Visual Inspection8.1 Units shall be free of defects that interfere with theproper

21、 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 manufacturer shall be permitted to remove unitsfrom the shipment. A new sample shall be selected by thepurchaser from remaining units from th

22、e shipment with asimilar configuration and dimension 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

23、requirements, theremaining portion of the shipment represented by the 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 requi

24、rements 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, the cost is typically borneby the purchaser.10.
