ASTM A862/A862M-98(2020) pdf free download.Standard Practice for Application of Asphalt Coatings to Corrugated Steel Sewer and Drainage Pipe.
ASTM A862/A862M-98(2020) covers the post coating of corrugated steel pipe and corrugated structural steel plate with asphalt materials. This practice is intended for shop-applied coating only.
Significance and Use
Asphalt coating is used to provide additional protection for corrugated steel products (product) in corrosive or abrasive environments, or both.
Classification
This practice covers three separate and distinct classifications of coatings. The general conditions under which these coatings are used are described in Specification A849.
Classification B1, Asphalt, Half Coated with Paved Invert—A uniform coating is applied to the interior and exterior of the pipe covering at least 50 % of the circumference on the lower portion of the pipe as installed, and then a paving is applied on the lower portion of the interior of the pipe as installed (the invert) to provide a smooth flow line.
Coating Application—Apply the asphalt coating by inserting the product into the bath twice; the first application results in a thin coating to achieve very good adherence, and the second achieves the coating thickness required by Specification A849.
Keywords:
asphalt coated steel pipe; asphalt coating; asphalt coating repair; coating application; corrugated steel pipe; paved invert; protective coatings; smooth lined.
