The following has been added to our False Claims of Accreditation page. Please visit that page for a current list of any known false claims of AASHTO Accreditation.

Monday, July 31, 2023, AASHTO released the Standard Specifications for Transportation Materials and Methods of Sampling and Testing, and AASHTO Provisional Standards, 43rd Edition—2023 (the “Materials Standards”).

Effective on July 1st, 2023, AASHTO re:source will suspend the Proficiency Sample Program Service to all participating CMT laboratories in the Kingdom of Saudi Arabia (KSA).

The following will be added to our scopes of services: AASHTO T 111, Standard Method of Test for Mineral Matter or Ash in Asphalt Materials, and ASTM D5334, Standard Test Method for Determination of Thermal Conductivity of Soil and Rock by Thermal Needle Probe Procedure.

As of January 19, 2023, AASHTO Accredited laboratories are no longer required to submit quality manual policies and procedures prior to the on-site assessment.

Registration is now open for the 2023 AASHTO re:source Technical Exchange!

Due to concerns with the accuracy of email alerts that are automatically generated through the Proficiency Sample Program for low ratings or failure to submit data, AASHTO re:source has suspended this notification service for AASHTO Accredited laboratories and registered specifiers.

The following was recently added to our scopes of services: ASTM D7012 Standard Test Methods for Compressive Strength and Elastic Moduli of Intact Rock Core Specimens under Varying States of Stress and Temperatures - Method D.

Participants that do not pay their annual PSP invoice within 30 days of receipt will have their enrollment cancelled. Because of the amount of time it takes our staff to reenroll participants, if your lab’s enrollment is cancelled and needs to be reenrolled, you will be charged a fee of $100.

The sample scheme known as the Asphalt Mixture Hveem Design Samples will be split into three distinct programs based on the method of compaction used to prepare the specimens.

After a preliminary review of the 42nd edition of the AASHTO Materials Standards, we anticipate many standards will require additional changes before we can begin complete enforcement of the new requirements throughout our programs. ​

The AASHTO Accreditation Program (AAP) is raising its annual administrative fees starting on July 1, 2022.

AASHTO re:source will resume on-site assessments (rather than remote assessments) in all parts of the United States starting July 25, 2022. We will continue to perform remote assessments for customers outside of the United States. We will continue to offer remote assessments for all laboratories that need a supplemental assessment in order to add standards to their current scope of accreditation.

As of April 13, 2022, the Duty of Care for On-Site Assessments has been updated. Please review it for the most current information.

ASTM D7263, Standard Test Methods for Laboratory Determination of Density and Unit Weight of Soil Specimens, has been added to our scopes of service for the assessment and accreditation programs.

ASTM D8225, Standard Test Method Determination of Cracking Tolerance Index of Asphalt Mixture Using the Indirect Tensile Cracking Test at Intermediate Temperature, has been added to our scopes of service for the assessment and accreditation programs.

After careful planning, AASHTO will begin conducting on-site assessments in states/territories where available information indicates that COVID-19 conditions are safe for travel. COVID-19 data will be monitored continually until all assessments in the state are complete.

At this time, we will continue to conduct remote assessments until further notice. When a new target date for return to on-site assessments has been determined, we will inform customers via email, our website, and social media. We will send another update to customers no later than October 3, 2021.

On Friday, July 30, 2021, AASHTO released the Standard Specifications for Transportation Materials and Methods of Sampling and Testing, and AASHTO Provisional Standards, 41st Edition—2021 (the “Materials Standards”). Be advised that AASHTO currently released the PDF Download version of the standards; the five-volume paperback version is being printed and will be available to purchase in September 2021.

In June, we announced our plan to return to on-site assessments in September. After careful consideration, AASHTO re:source has made the difficult decision to postpone this return to on-site assessments.
