AASHTO MP 42-20 PDF Download

AASHTO MP 42-20 is a standard specification that outlines the requirements and test methods for steel-reinforced polyethylene (SRPE) corrugated pipe. This standard applies to pipe sizes ranging from 300 to 1800 mm (12 to 72 inches) and is designed for use in surface and subsurface drainage applications.

The standard covers various aspects including the materials used, workmanship, dimensions, pipe stiffness, impact resistance, joining systems, and form of markings. It ensures the quality and performance of SRPE corrugated pipe to meet the needs of drainage systems.

The primary purpose of SRPE corrugated pipe is to collect and convey drainage water through open gravity flow. It is commonly used as culverts, storm drains, and other applications where the soil provides support to its flexible walls.
