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

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
