Our standard of excellence works for you

"Nobody ever questions us when we submit our accreditations for a project based on procedures, proficiency sampling or lab audits. It gives us a good feeling that every time we do an audit, it will meet the minimum standards that are accepted in the Northeast."

  • Seven Steps for a "Perfect" On-Site Assessment

    We all realize that having a perfect on-site assessment is no small accomplishment. However, there are some rather simple steps your laboratory can take to ensure that the assessment runs smoothly and relatively error-free. The staff at AASHTO re:source understands what a special event the on-site assessment is for each of our customers, and that it can be an overwhelming process. The goal of this article is to give you a few pointers on preparing for your on-site assessment. Following these steps will help you get the most out of the assessment process and ensure that it runs as smoothly as possible.

  • Suggestions Anyone? The ABC’s of Customer Feedback

    Ah the dreaded customer feedback request. Don’t you hate being bombarded with those everywhere you go? Restaurants, stores, hotels, on-line retailers, customer service reps, AASHTO re:source, etc. – the list never ends! I mean, do they even do anything with that information? Yes! Or at least they should.

  • Technician Certification Requirements in ASTM Standards

    It has been over a year since we started to request technician certification information during a laboratory’s annual review for AASHTO accreditation rather than during the on-site assessment if the laboratory is accredited for ASTM C1077, D3666, D3740, or E329. This change was made to improve the consistency of our assessment of laboratory conformance to the ASTM quality system standards that require technician certifications. A consistent evaluation ensures that all AASHTO-accredited laboratories throughout the country are treated fairly and that our program can better meet the needs of the agencies that specify accreditation for these standards.

  • The Great Aggregate & Rebar Debate: Who Should Perform Your Assessment?

    In this episode of AASHTO Resource Q&A, we tackle a frequently asked question that has significant implications for construction materials laboratories: Who should perform your aggregate and rebar assessments—CCRL or AASHTO re:source? This seemingly straightforward question opens a complex discussion about the best choice for your lab’s assessment needs.

  • The History of the AASHTO Accreditation Program

    The AASHTO Accreditation Program (AAP) was established in 1988 to provide a mechanism for formally recognizing the competency of testing laboratories to perform specific tests on construction materials. Some of you who know the history of the industry may be surprised that the AAP is so young because the AASHTO re:source and CCRL (Cement and Concrete Reference Laboratory) have been around much longer. In fact, the AASHTO re:source was founded in 1965 and the CCRL was established in 1929, as the Cement Reference Laboratory (CRL). The AASHTO re:source and CCRL are collectively known as the Construction Materials Reference Laboratories (CMRL).

  • The Road to Developing an Effective Quality Management System – Part 2, Getting Started

    It's time to hit the road and get this QMS thing started! The first part of my series (Part 1 – Why Bother?) focused on the many benefits of developing and implementing an effective QMS. Let’s see where this road will take us next.

  • The Road to Developing an Effective Quality Management System (QMS): Part 1 - Why Bother?

    Ease up on those brakes! Developing an effective QMS does require precious time and resources, but the benefits will far outweigh the work involved when the procedures and processes are followed and continually improved. An organization can benefit from developing and implementing an effective QMS in many ways. Here are some of the best:

  • The Road to Developing an Effective Quality Management System (QMS): Part 3 – Finish What You Started

    ​Before we end this journey, let’s go over the road we’ve traveled thus far. In Part 1, you learned what a QMS is and some of the many benefits of having an effective QMS. I also discussed developing a quality policy statement and goals, and how a quality manual is the handbook to a QMS. In Part 2, I taught you how to get started with developing your QMS documentation, and you learned some tips to help ensure your documentation is effective. Now it’s time to head for the finish line! Along the way, I will be taking some U-turns to elaborate on a few things previously mentioned in my series, such as maintaining your QMS, getting buy-in from others, and document control.

  • What's the Difference? Accreditation, Certification, and Related Terms

    As we look back on 50 years of contributions to quality and excellence in materials testing at AASHTO re:source, we reflect on the largest turning points that have led to the program’s success. One such event that marks a proud moment in AASHTO re:source history occurred in 1988 when the AASHTO Accreditation Program (AAP) was established. The program was developed to provide a mechanism to formally recognize the competency of construction materials testing laboratories. (Check out The History of the AASHTO Accreditation Program for more information.) As we look back on this historic occasion, we reflect on the term “accreditation” and its essential role in construction materials testing.
