- 2 1021.2 Procedure
- 3 1021.3 Sample Record
(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.
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 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.
1021.2.3 Identification Markings
Pipe is to be marked as described in 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 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 1020.2.5 Field Inspection.
Fabrication of bituminous-coated corrugated metal culvert pipe and pipe arches shall be in accordance with 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 1020.3 Sample Record.
