AASHTO R 63-13（2021）为工程师提供了HDPE导管规范方面的指导，HDPE导管用于埋地应用，用于保护公路、机场照明、交通控制和光纤数据以及州交通项目中的指挥和控制应用中的电力电缆。本标准实施规程涵盖以下方式使用的导管:HDPE管用作保护道路交叉口中较小单独导管、内导管的套管；盘管、钢卷或直棒中的HDPE导管；andCIC（导管内电缆），当电力电缆（导体）、有线电视（同轴电缆）或光纤电缆安装在导管制造厂的导管内时。 HDPE管通常安装在独立管道装置中，用于保护电力电缆、有线电视或光纤电缆。HDPE管通常安装在独立管道中，用于道路交叉口，埋深足以避免对道路造成降解影响。HDPE管道通常安装在平行于道路的独立管道应用中。

AASHTO R 63-13 (2021) provides guidance to engineers in the specification of HDPE conduit used in buried applications for the protection of power cables for use in highways, airport lighting, traffic control and fiber optic data and command and control applications in State Transportation Projects.This standard practice covers conduit used in the following manner:HDPE pipe used as a casing for the protection of smaller individual condui9ts, innerducts, in road crossings;HDPE conduit in coils, on steel reels, or in straight sticks; andCIC (cable in conduit), when power cable (conductors), CATV (coaxial), or fiber optic cable is installed in the conduit at the conduit manufacturing facility.HDPE pipe is commonly installed in standalone duct installations for the protection of power cable, CATV, or fiber optic cable.HDPE pipe is commonly installed in standalone duct applications for road crossings when the bury depth is sufficient to avoid degration effects to the road.HDPE pipe is commonly installed in standalone duct applications parallel to the roadway.
