3、(June 2017) ASTM Designation C506M-16b and C506-16b 1. SCOPE 1.1. This specification covers reinforced arch-shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts. 1.2. This specification is applicable for orders in either S

4、I units (M 206M) or in inch-pound units (M 206). SI units and inch-pound units are not necessarily equivalent. Inch-pound units are shown in brackets in the text for clarity, but they are the applicable values when the material is ordered to M 206. Note 1This specification is a manufacturing and pur

5、chase specification only, and does not include requirements for bedding, backfill, or the relationship between field load condition and the strength classification of pipe. However, experience has shown that the successful performance of this product depends on the proper selection of the class of p

6、ipe, type of bedding and backfill, and care that the installation conforms to the construction specifications. Owners of the reinforced concrete pipe specified herein are cautioned that they must correlate the field requirements with the class of pipe specified and provide inspection at the construc

7、tion site. 2. REFERENCED DOCUMENTS 2.1.

Pipe manufactured according to this specification shall be of three classes identified as Class A-II, A-III, and A-IV. The strength requirements are pre

13、scribed in Table 1 for SI units or Table 2 for inch-pound units. 5. BASIS OF ACCEPTANCE 5.1. Unless otherwise designated by the owner at the time of or before placing an order, there are two separate and alternative bases of acceptance. Independent of the method of acceptance, the pipe shall be desi

14、gned to meet both the 0.3-mm 0.01-in. crack and ultimate strength requirements. 5.1.1. Acceptance on Basis of Plant Load Bearing Tests, Material Tests, and Inspection of Manufactured Pipe for Visual Defects and ImperfectionsAcceptability of the pipe in all diameters and classes produced in accordanc

15、e with Section 7.1 or Section 7.2 shall be determined by the results of the three-edge-bearing tests as defined in Section 11.3.1; by such material tests as are required in accordance with Sections 6.2, 6.3, 6.5, and 6.6; by an absorption test of the concrete from the wall of the pipe as required in

16、 11.9; and by visual inspection of the finished pipe to determine its conformance with the accepted design and its freedom from defects. 5.1.2. Acceptance on Basis of Material Tests and Inspection of the Complete ProductAcceptability of the pipe in all diameters and classes produced in accordance wi

17、th Section 7.1 or 7.2 shall be determined by the results of such material tests as are required in Sections 6.2, 6.3, 6.5, and 6.6; by crushing tests on concrete cores or cured concrete cylinders; by an absorption test of the concrete from the wall of the pipe for each mix design that is used on an

18、order; and by inspection of the finished pipe, including amount and placement of reinforcement, to determine its conformance with the accepted design and its freedom from defects. 5.1.3. When agreed upon by the owner and the manufacturer, any portion or any combination of tests itemized in Section 5

19、.1.1 or Section 5.1.2 may form the basis of acceptance. 2017 by the American Association of State Highway and Transportation Officials.All rights reserved.
