本标准实施规程包含建立和实施公路施工用标准制造材料质量保证（QA）程序的最低标准和指南。本文件旨在为制造商制定最低质量控制（QC）要求，并为运输机构验收标准制造材料提供指南。标准制造材料——交通建设中使用的材料根据其来源和相应的生产方法进行广泛分类。三种主要材料类别如下:项目生产材料、装配式结构材料和标准制造材料。 标准制造材料是由制造商常规生产（即，非特定项目）的标准件。它们通常具有以下一个或多个特征:材料通常是在高度控制和高度自动化的制造条件下批量生产的。材料性能稳定，在从制造商到项目现场的适当运输条件下，不会发生变化。材料以坚固的成品状态到达项目现场，只需安装。

This standard practice contains minimum criteria and guidelines for establishing and implementing quality assurance (QA) procedures forstandard manufactured materialsused in highway construction. The purpose of this document is to establish minimum quality control (QC) requirements for manufacturers and to provide guidelines for acceptance of standard manufactured materials by transportation agencies.Materials used in transportation construction are broadly categorized according to their source and corresponding methods of production. The three principal materials categories are as follows:Project-produced materials,Fabricated structural materials, andStandard manufactured materials.Standard manufactured materials are standard items that are produced routinely (i.e., not for a specific project) by a manufacturer. They are generally characterized by one or more of the following conditions:The materials are normally mass-produced under highly controlled and largely automated manufacturing conditions.The material properties are stable and have no potential for alteration under proper transportation from the manufacturer to the project site.The materials arrive at the project site in a solid, finished state and require only installation.
