标准摘要
[中文适用范围]： 本文件规定了组成材料和成品混凝土轨枕和支座（即预制混凝土轨枕、双块钢筋轨枕、道岔和道口支座以及铁路专用元件）需要满足的技术标准和控制程序。 曲目。 本文件定义了机械测试，以确保轨枕或承载者抵抗重复负载的能力并提供足够的耐用性。 此外，它还对制造过程和测试进行控制，以确保混凝土在使用过程中不会因化学反应和冻害而发生降解。 [外文原描述]： This document defines technical criteria and control procedures which need to be satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e. precast concrete sleepers, twin-block reinforced sleepers, bearers for switches and crossings, and special elements for railway tracks. This document defines mechanical tests which provide assurance of the capability of sleepers or bearers to resist repetitive loading and provide sufficient durability. In addition, it places controls on manufacturing processes and tests to ensure that the concrete will not suffer degradation in service through chemical reaction and frost damage.
