In this episode of AASHTO re:source 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.

Understanding the Overlap and Beyond
Both CCRL and AASHTO re:source offer assessments for a variety of construction materials, but aggregate and rebar are the only areas where their services overlap. We delve into why both organizations provide these assessments, highlighting that these materials are essential components in construction projects involving concrete, masonry, and general construction materials. This overlap is driven by customer demand, as laboratories often require comprehensive assessments that cover multiple materials.

While CCRL’s assessment focuses on tensile and bend testing for rebar, AASHTO re:source offers a broader scope that includes various iron and steel products. Understanding these distinctions is crucial for laboratories to align their assessments with specific project requirements. Participation in the perspective proficiency sample programs is mandatory for AASHTO Accreditation, regardless of the assessment provider.

Key Considerations
This episode also explores the key factors that laboratories must consider when choosing an assessment provider. While CCRL might offer advantages for specific tests, such as rebar, these can be offset by scheduling challenges and the need for additional assessments from AASHTO re:source. Timing is a critical factor, influencing both cost and accreditation continuity, so understanding the scheduling and cost implications is essential for seamless operations. Both CCRL and AASHTO re:source have different tour schedules, and the timing of your request can significantly affect the overall cost.

Laboratories must consider the total scope of their assessment needs, the cost-effectiveness of each provider, and personal preferences based on past experiences. For example, if a lab requires assessments for multiple materials beyond aggregate and rebar, AASHTO re:source might be the more efficient choice.

Making an Informed Decision
To make an informed decision, laboratories should gather detailed information from both organizations. CCRL has a price sheet on their website, and AASHTO re:source provides an online request form for estimates. Understanding the potential out-of-sequence fees and the specific scope of services needed will help laboratories determine the most cost-effective and timely option.

Navigating the Transition Between Providers
Switching between CCRL and AASHTO re:source requires careful planning to avoid accreditation gaps. Laboratories must ensure an overlap in assessments and be aware of potential out-of-sequence fees if the preferred provider’s schedule does not align with immediate needs. This strategic approach helps laboratories maintain accreditation and operational efficiency.

Conclusion
In “The Great Aggregate & Rebar Debate: Who Should Perform Your Assessment?”, we provide a comprehensive exploration of the factors influencing the choice of assessment provider in the construction materials industry. From cost considerations to timing challenges, these insights empower laboratories to make informed decisions that align with their specific needs and objectives.
