摘要

To prepare its bid packages, the City refers to "Standard Specifications for Public Works Construction" better known as "Green Book." The publication's purpose is to further the uniformity of construction standards in the industry. Products and materials that are used for sewer construction and rehabilitation must pass rigorous performance testing per Green Book Section 211-2 Chemical Resistance (known as the Pickle Jar Test). This is an accelerated aging test used to determine the physical properties and weight change of material specimens after exposure to a chemical solution. This qualification test can then determine if a liner material is fit for sewer applications and can meet a minimum 50-year design life.
