18、TIONS*NOTE: Pervious pavement systems shall be installed in areas with gently sloping or flat ground, light traffic, limited heavy truck use, and where pavements will not receive snow and ice treatments (salt, sand, or chemical). Consult manufacturers recommendations for cold regions, arid regions,
19、and regions with high wind erosion. Parking lots are generally good pervious pavement applications. Installing pervious pavement systems contributes to the following LEED credit: SS6.*Pervious pavement systems shall use Section 32 11 16.16 BASE COURSE FOR RIGID AND SUBBASE COURSE FOR FLEXIBLE SUBBAS
20、E COURSE FOR PERVIOUS PAVING, and Section 32 13 43 PERVIOUS CONCRETE PAVING, 32 10 00 PERVIOUS BITUMINOUS CONCRETE PAVEMENT and 32 12 10 BITUMINOUS TACK AND PRIME COATS, in addition to this section.1.3 SUBMITTALS*NOTE: Submittals must be limited to those necessary for adequate quality control. The i
21、mportance of an item in the project should be one of the primary factors in determining if a submittal for the item should be required.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G
22、” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters wi
23、thin the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the District Office); “A
24、O“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office. Codes following the “G“ typically are not used for Navy projects.Submittal items not designated with a “G“ are considered as being for information only for Army projects and for Contractor Quality Control approval for Navy pr

Calibrated equipment, such as scales, batching equipment, spreaders, and similar items, shall have been recalibrated by an approved calibration laboratory
32、 a State calibration laboratory within 12 _ months of commencing work.1.7 SUSTAINABLE DESIGN REQUIREMENTS1.7.1 Local/Regional Materials*NOTE: Using local materials can help minimize transportation impacts, including fossil fuel consumption, air pollution, and labor. Using materials harvested and man
33、ufactured within a 500 mile radius from the project site contributes to the following LEED credit: MR5. Coordinate with Section 01 33 29 LEED(tm) DOCUMENTATION. Use second option if Contractor is choosing local materials in accordance with Section 01 33 29 LEED(tm) DOCUMENTATION. Use second option f
34、or USACE projects. Army projects shall include option only if pursuing this LEED credit.*Use materials or products extracted, harvested, or recovered, as well as manufactured, within a 800_ kilometer 500_ mileradius from the project site, if available from a minimum of three sources.See Section 01 3
35、3 29 LEED(tm) DOCUMENTATION for cumulative total local material requirements. Aggregate materials may be locally available.PART 2 PRODUCTS2.1 MATERIALS2.1.1 Aggregates*NOTE: Maximum amount of material passing 75 micrometers No. 200 sieve for 50 mm 2 inch maximum should not be more than 7 percent, fo
36、r 38 mm 1 1/2 inch maximum 8 percent, and for 25 mm one inch maximum 9 percent, where frost is a factor in design.*NOTE: Delete percentage of wear and weight of slag not applicable to the project. For pavement designed for aircraft equipped with tires having pressure of 1725 kPa 250 psi or more, the
37、 percentage of wear should not exceed 40; and for slag, the weight should be not less than 1120 kg per cubic meter 70 pounds per cubic foot; for tire pressures SECTION 32 11 24 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-less than 1725 kPa
38、250 psi, the percentage of wear may be increased to 45; and for slag, the weights may be reduced to 29.4 kg 65 pounds. The requirements of 40 or less for wear test under high pressure tires may be increased to 45 if a satisfactory service record can be demonstrated.*NOTE: Delete the sizes which are
39、unsuitable for the thickness of the base course layer to be constructed or are not available. The compacted thickness of any compacted base course layer should be limited to a maximum of 150 mm 6 inches and a minimum of 75 mm 3 inches. The gradations may be modified to suit local conditions; however
40、, the composite material must meet the required California Bearing Ratio. Prior to specifying any modified gradation, tests should be performed using the material to be incorporated in the base course to determine whether the modified gradation will provide the required California Bearing Ratio.*NOT
41、E: Use of materials with recycled content, calculated on the basis of post-industrial and post-consumer percentage content, contributes to the following LEED credit: MR4. Coordinate with Section 01 33 29 LEED(tm) DOCUMENTATION. Designer must verify that products meeting the indicated minimum recycle
42、d content are available, preferably from at least three sources, to ensure adequate competition. If not, write in suitable recycled content values that reflect availability and competition. Use second option if Contractor is choosing recycled content products in accordance with Section 01 33 29 LEED
