CHARACTERIZATION VS. SPECIFICATION

In the absence of performance tests, the construction industry has often substituted specifications that address material characteristics and properties of the individual components and mixtures. As a result, there are a plethora of specifications that are dealing with properties that may or may not relate to the performance of the material. In addition, the test methods may have poor precision leading to acceptance issues. This is most prevalent on aggregates and materials that include aggregates as a component. If the proper test methods and equipment that could adequately measure performance were available, materials specifications could be simplified and provide greater assurances that these materials would perform as intended with greater confidence that properties were correctly measured.
