This article establishes procedures for inspecting, acceptance and reporting of bituminous-coated corrugated metal culvert pipe and pipe arches.  Refer to [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=14 Sec 1021] for MoDOT’s specifications.

For Laboratory testing and sample reporting procedures, refer to EPG 1021.4 Laboratory Testing Guidelines for Sec 1021.

==1021.1 Apparatus==
(a) Micrometer capable of measuring to 0.0001 in. (0.00254 mm) and accurate to within at least 0.001 in. (0.0254 mm).

(b) Rule with suitable gradations to accurately measure the material to be inspected.

(c) The [[1020.5 Corrugated Metal Pipe (CMP) Inspection Guide|Corrugated Metal Pipe (CMP) Inspection Guide]].

==1021.2 Procedure==

===1021.2.1 Bituminous-Coated Corrugated Metal Culvert Pipe===
Bituminous-coated corrugated metal culvert pipe and pipe arches are to be accepted in accordance with [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=14 Sec 1021.2].  The basis of acceptance for the bituminous material will be in accordance with AASHTO M 190, except acceptance may be based on samples obtained from storage or from the dipping tanks.

===1021.2.2 Material===
The pipe shall be in accordance with [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=14 Sec 1020] and [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=14 Sec 1024]. The bituminous material shall be in accordance with AASHTO M 190.

===1021.2.3 Identification Markings===
Pipe is to be marked as described in [[:category:1020 Corrugated Metallic-Coated Steel Culvert Pipe, Pipe-Arches and End Sections#1020.2.3 Identification Markings for Steel Sheet|EPG 1020.2.3 Identification Markings for Steel Sheet]].

===1021.2.4 Random Sampling===
Random samples of steel sheet are to be taken as described in [[:category:1020 Corrugated Metallic-Coated Steel Culvert Pipe, Pipe-Arches and End Sections#1020.2.4 Random Sampling of Steel Sheet|EPG 1020.2.4 Random Sampling of Steel Sheet]]. Random samples of bituminous coating are to be taken in accordance with AASHTO M 190.

===1021.2.5 Field Inspection===
Field inspection shall be performed in accordance with and at the frequency specified in [[:category:1020 Corrugated Metallic-Coated Steel Culvert Pipe, Pipe-Arches and End Sections#1020.2.5 Field Inspection|EPG 1020.2.5 Field Inspection]].

===1021.2.6 Fabrication===
Fabrication of bituminous-coated corrugated metal culvert pipe and pipe arches shall be in accordance with [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=14 Sec 1020] and AASHTO M 190.

===1021.2.7 Lift Hooks or Loops===
Lift hooks or loops, if agreed upon by the engineer and manufacturer, may be attached to pipe and pipe arches to facilitate handling.

===1021.2.8 Repair of Damaged Bituminous Coating===
Bituminous coating damaged or displaced during delivery or installation shall be repaired as directed the engineer by application of hot bituminous material of the same type as that originally used. Care shall be taken to avoid damage to the bituminous materials during heating.

==1021.3 Sample Record==
Sample IDs shall be assigned and sample records shall be created in accordance with [[:category:1020 Corrugated Metallic-Coated Steel Culvert Pipe, Pipe-Arches and End Sections#1020.3 Sample Record|EPG 1020.3 Sample Record]].

==1021.4 Laboratory Testing Guidelines for [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=14 Sec 1021]==
This article To establish procedures for Laboratory testing and reporting samples of bituminous material for coating corrugated metal culvert pipe and pipe-arches.

===1021.4.1 Procedure===
Bituminous material shall be tested according to AASHTO M190.  Original test data and calculations shall be recorded in Laboratory workbooks.  Test results shall then be recorded through AASHTOWARE Project (AWP).

===1021.4.2 Sample Record===
The sample record shall be completed in AASHTOWARE Project (AWP) in accordance with [[:Category:101 Standard Forms #Sample Record, General|AWP MA Sample Record, General]] and shall indicate acceptance, qualified acceptance or rejection.  Appropriate remarks, as described in [[106.20 Reporting|EPG 106.20 Reporting]], are to be included in the remarks to clarify conditions of acceptance or rejection.  Test results shall be reported on the appropriate templates under the Tests tab.
