AASHTO R 25-19 PDF Download

AASHTO R 25-19 is a standard practice that aims to establish procedures for training, evaluating, and certifying technicians involved in the sampling and testing of various materials such as soils, aggregates, asphalt mixture, and portland cement concrete. It is specifically designed to comply with AASHTO test methods. The standard is primarily intended for organizations responsible for certifying technicians at the basic testing level for acceptance of materials and independent assurance testing.

The standard uses generic terms such as "technician" and "certification" to describe the individuals and their qualifications. However, it clarifies that the term "qualification" is essentially equivalent to "certification" within this standard. It also acknowledges that each state may have its own terminology and may need to adapt these terms in accordance with their specific laws and practices.

It is important to note that this standard does not cover every eventuality or procedure related to the administration and use of a technician certification program (TCP). However, it provides a comprehensive guideline for setting up and implementing such programs to ensure that technicians are adequately trained and qualified in accordance with industry-recognized standards.
