20、SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are alr
21、eady 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. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval on
22、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 for Army projects using the Resident Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division
23、 or other organization in the District 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 seco

Copies of field test results within 24 _ hours after the tests are performed. Test
27、results from samples, not less than 30 _ days before material is required for the work. Results of laboratory tests for quality control purposes, for approval, prior to using the material.1.4 QUALITY ASSURANCE*NOTE: Field density tests and laboratory tests are generally performed at a frequency of o
28、ne set of tests for every 1,000 square meters (yards) of completed area. Other frequency intervals may be specified when conditions warrant. It is important that both field density tests and laboratory tests be conducted on the same materials.*Sampling and testing is the responsibility of the Contra
29、ctor. Sampling and testing shall be performed by an approved commercial testing laboratory or by the Contractor, subject to approval. If the Contractor elects to establish its own testing facilities, approval of such facilities will be based on compliance with ASTM D 3740. No work requiring testing
30、will be permitted until the Contractors facilities have been inspected and approved.1.4.1 SamplingTake samples for material gradation, liquid limit, and plastic limit tests in conformance with ASTM D 75. When deemed necessary, the sampling will be observed by the Contracting Officer.SECTION 32 15 00

Approval of sources not already approved by the Corps of Engineer
33、s will be based on an inspection by the Contracting Officer. Tentative approval of materials will be based on appropriate test results on the aggregate source. Final approval of the materials will be based on tests for gradation, liquid limit, and plasticity index performed on samples taken from the
34、 completed and compacted surface course.1.4.4 Equipment*NOTE: If desirable, requirements for types of equipment applicable to methods of construction based on local conditions will be included.*All plant, equipment, and tools used in the performance of the work covered by this section will be subjec
35、t to approval by the Contracting Officer before the work is started and shall be maintained in satisfactory working condition at all times. The equipment shall be adequate and shall have the capability of producing the required compaction, and meeting the grade controls, thickness controls, and smoo
36、thness requirements set forth herein.1.5 ENVIRONMENTAL REQUIREMENTS*NOTE: The first sentence of this paragraph may be deleted in localities where freezing temperatures do not occur.*Aggregate surface courses shall not be constructed when the ambient temperatures is below 2 degrees C 35 degrees F and
37、 on subgrades that are frozen or contain frost. It is the responsibility of the Contractor to protect, by approved method or methods, all areas of surfacing that have not been accepted by the Contracting Officer. Surfaces damaged by freeze, rainfall, or other weather conditions shall be brought to a
38、 satisfactory condition by the Contractor.PART 2 PRODUCTS2.1 AGGREGATES*NOTE: As written, this paragraph applies to general SECTION 32 15 00 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-conditions. Other materials such as disintegrated grani
39、te, volcanic ash or cinders, limerock, and caliche will be specified when supported by adequate performance data. The requirement for soundness and percentage of wear will be deleted when local experience indicates the material is satisfactory.The gradation or gradations applicable to the specific j
40、ob will be specified. The gradations shown are recommended, but others may be used where they have been used successfully. The liquid limit and plasticity index specified are normally used, but may be changed as required. Gradations No. 3 and No. 4 may be susceptible to frost damage.When an aggregat
41、e surfacing is used in construction of Army Class IV airfields, paragraph PROOF ROLLING will be retained, and the extent of proof rolling will be precisely shown on the drawings. When using the specifications for an aggregate surface course subjected to highway vehicular traffic such as roads, stree
42、ts, and parking areas or for Army Class I, II, and III airfields, references to proof rolling will be deleted in paragraph AGGREGATES, and paragraph PROOF ROLLING will be deleted.*Provide aggregates consisting of clean, sound, durable particles of natural gravel, crushed gravel, crushed stone, sand,
43、 slag, soil, or other approved materials processed and blended or naturally combined. Provide aggregates free from lumps and balls of clay, organic matter, objectionable coatings, and other foreign materials. The Contractor is responsible for obtaining materials that meet the specification and can be used to meet the grade and smoothness requirements specified herein after all compaction and proof rolling operations have been completed.2.1.1 Coarse Aggregates*NOTE: A percentag
