AASHTO T 281-14 (2018) PDF Download

The AASHTO T 281-14 (2018) standard provides guidelines for testing vitrified clay pipes before their installation. The standard includes various test methods for assessing the quality and performance of the pipes.

The standard covers tests that evaluate the resistance of the pipe to crushing and hydrostatic forces using whole pipe specimens. These tests help determine the structural integrity of the pipe by subjecting it to simulated loads and pressures that it may encounter during its service life.

Additionally, the standard includes tests using pipe fragments to measure the water absorption capacity of the pipe body. This information is important in evaluating the ability of the pipe to maintain its structural integrity when subjected to moisture or wet conditions. Furthermore, the standard also assesses the quantity of acid-soluble material that can be extracted from the pipe. This test provides important data about the chemical composition of the pipe material and its potential impact on the environment or any connected systems.
