AASHTO MP 40-19 PDF Download

AASHTO MP 40-19 is a standard specification that outlines the requirements and testing methods for steel-reinforced polyethylene (PE) ribbed pipe with diameters ranging from 1650 to 3000 mm (66 to 120 inches). The standard covers various aspects such as materials, workmanship, dimensions, perforation, pipe stiffness, impact resistance, tensile strength of seams, shape stability, joining systems, and markings.

The steel-reinforced PE ribbed pipe is primarily used for surface and subsurface drainage applications. It is designed to be flexible and rely on the support provided by the surrounding soil. The pipe is commonly used as culverts and storm drains to collect and transport drainage water using gravity flow.

It is important to consider the protection of the exposed portions of the pipe when it is used in locations where the ends may be exposed. This is due to the combustibility of the PE material and the potential effects of prolonged exposure to ultraviolet radiation and corrosion of the steel reinforcement.

It is worth noting that this specification solely focuses on the materials requirements of the steel-reinforced PE ribbed pipe. The structural design of the culverts and the proper installation procedures are covered in other AASHTO publications such as the LRFD Bridge Design Specifications and the LRFD Bridge Construction Specifications. The manufacturer is expected to provide detailed profile wall section information upon request for a thorough engineering evaluation.
