AASHTO M 335-19涵盖了表面和地下排水应用中使用的钢骨增强聚乙烯（PE）带肋管、联轴器和配件的要求和试验方法。标称尺寸为300至1500毫米（12至60英寸）包括在内。规定了材料、工艺、尺寸、管道刚度、抗冲击性、接缝抗拉强度、形状稳定性、连接系统和标记形式。钢骨增强聚乙烯带肋管用于地表和地下排水应用，土壤为其柔性壁提供支撑。其主要用途是通过开放式重力流收集或输送排水，如涵洞、雨水沟等。注1:当在末端可能暴露的位置使用PE管时，应考虑保护暴露部分，因为PE的可燃性和长期暴露在紫外线辐射下的影响。 本规范仅涉及管道材料要求。《ASHTO LRFD桥梁设计规范》第12节和《ASHTO LRFD桥梁施工规范》第26节分别给出了钢骨增强热塑性涵洞的结构设计和正确的安装程序。根据用户或工程师的要求，制造商应提供全面工程评估所需的剖面墙截面详图。

This specification covers the requirements and methods of tests for steel-reinforced polyethylene (PE) ribbed pipe, couplings, and fittings for use in surface and subsurface drainage applications.Nominal sizes of 300 to 1500 mm (12 to 60 in.) are included.Materials, workmanship, dimensions, perforation, pipe stiffness, impact resistance, tensile strength of seams, shape stability, joining systems, and form of markings are specified.Steel-reinforced PE ribbed pipe is intended for surface and subsurface drainage applications where soil provides support to its flexible walls. Its major use is to collect or convey drainage water by open gravity flow as culverts, storm drains, etc.Note—When SRPE corrugated pipe is to be used in locations where the ends may be exposed, above ground, consideration should be given to protection of the exposed portions due to combustibility of polyethylene and the effects of prolonged exposure to ultraviolet radiation, as well as corrosion of steel reinforcement.This specification only deals with this pipe’s materials requirements. The structural design of steel reinforced thermoplastic culverts and the proper installation procedures are given in theAASHTO LRFD Bridge Design Specifications, Section 12, andAASHTO LRFD Bridge Construction Specifications, Section 26, respectively. Upon request of the user or engineer, the manufacturer shall provide profile wall section detail required for a full engineering evaluation.This standard was formerly designated as provisional standard MP 20.
