AASHTO R 38-10 (2018) PDF Download

The AASHTO R 38-10 (2018) standard provides minimum criteria and guidelines for implementing quality assurance procedures for standard manufactured materials used in highway construction. The purpose of this standard is to establish quality control requirements for manufacturers and provide guidelines for transportation agencies to accept these standard manufactured materials.

Standard manufactured materials are a category of materials used in transportation construction that are produced regularly by a manufacturer, not for a specific project. These materials are typically mass-produced under controlled and automated conditions. They have stable properties that do not change during transportation from the manufacturer to the project site. When the materials arrive at the project site, they are in a solid, finished state and only require installation.

This standard practice ensures that manufacturers meet minimum quality control requirements and provides guidelines for transportation agencies to ensure the acceptance of these standard manufactured materials. It aims to ensure consistent quality and reliability in the use of these materials for highway construction projects.
