Diamond Quality Commendation


The Diamond Quality Commendation focuses on plant practices resulting in excellent product quality. The Diamond Quality Commendation extends the idea of a blueprint for excellence to the pavement material that is produced.

The 2017 application has undergone a full revision by industry experts so that current technologies and best practices are more fully represented.


The commendation evaluates quality management; RAP, RAS and aggregate handling; asphalt binder storage; drying and mixing; air quality; truck scales; silos; control rooms; training; and safety. Some questions are mandatory and require an appropriate response in order for the application to be eligible. Each individual area requires a minimum of 80 percent and the total score must be at least 85 percent to receive the Diamond Quality Commendation. Verification by a third party not affiliated with the company is required.


Batch plants and drum plants are handled separately as they require different practices, but the percentages needed for passing grades are the same.


All applications for the Diamond Quality Commendation are completed online. Supporting documentation such as technician certificates, laboratory accreditation, and third-party reviews are submitted in electronic format.
