Generally, the maximum size of aggregate for wearing course should not exceed 40 percent of the designed thickness of

15、 the course (i.e., course thickness divided by 2.5); in no case should the aggregate size exceed 25 mm one inch or one-half the thickness of the compacted wearing course or two-thirds the thickness of any binder or leveling course; gradation requirements for the leveling course should be specified t

16、o suit the project and may vary from a fine wearing course mix to a coarse binder course mix as dictated by project requirements. When appropriate, the wearing course mix may be specified as an option for the leveling and/or binder course mixes.*PART 1 GENERAL1.1 REFERENCES*NOTE: This paragraph is u

Submittals should be kept to the minimum required fo

30、r adequate quality control.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” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. O

31、nly 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 within the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes

32、 for Army projects using the Resident Management System (RMS) are: “AE“ for SECTION 32 12 17 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the Distric

33、t Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office. Codes following the “G“ typically are not used for Navy, Air Force, and NASA projects.Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects.*

34、Government approval is required for submittals with a “G“ designation; submittals not having a “G“ designation are for Contractor Quality Control approval.for information only. When used, a designation following the “G“ designation identifies the office that will review the submittal for the Governm
