What is the difference between AASHTO re:source and CCRL?
AASHTO re:source is part of the American Association of State Highway and Transportation Officials (AASHTO), which is sponsored by the state DOTs, the FHWA, the Port Authority of NY/NJ, the Washington DC DOT, and the Puerto Rico DOT. AASHTO re:source offers assessments and proficiency samples in the fields of asphalt binder, emulsified asphalts, hot mix asphalt, aggregate, soil, metals, and pavement preservation.

The Concrete and Cement Reference Laboratory (CCRL) is part of ASTM International, which is a standards organization that includes both private and public sector membership. CCRL offers assessments and proficiency samples in the fields of concrete, aggregate, cement, pozzolan, masonry, and metals.

If a laboratory is seeking AASHTO accreditation, they must submit all responses to nonconformities noted in the AASHTO re:source and/or CCRL report to the AASHTO Accreditation Program.
How do I register my laboratory with the AASHTO re:source website?
Registering a laboratory with the AASHTO re:source website will allow the user to request an assessment electronically, and will also provide the user with access to informative documents, tools, and resources that may assist in the assessment process. To register a laboratory, first obtain an Access Code and Passkey by completing the Request Laboratory Registration form or calling us at 240-436-4900. Once logged in with the assigned Access Code and Passkey, the user will be able to create a unique login associated with their email address and a password of their choosing.
I can’t login, what do I do?
If your laboratory is already registered in our system, click the Login link at the top of the page and use the Forgot Password feature. Enter the email address of your lab’s administrative user. A new password will be sent to that email address. Then copy and paste the new password into the appropriate field on the website. For a new laboratory not yet in our system, please complete the Request Laboratory Registration form.

Please contact our Administrative Staff directly, at 240-436-4900 or info@aashtoresource.org, if you cannot recall the email address your laboratory uses to login. We would be happy to assist you.

Can I change the email address I login with?
It is important that you login with an active and accessible email address. To change the email address that you use to login, please contact our Administrative Staff directly by emailing info@aashtoresource.org or calling 240-436-4900.
What are the Primary and Secondary Contacts?
Based on customer feedback, AASHTO re:source has updated the functionality of laboratory account contacts. Laboratory and Accreditation Contacts have been replaced with Primary and Secondary Contacts. The Primary and Secondary Contacts now receive copies of ALL automated emails from AASHTO re:source, including but not limited to: accreditation notifications, invoice reminders, proficiency sample alerts, and assessment report updates.

The Customer Contact has been replaced with Corporate Contact. The Corporate Contact is also being configured to receive copies of all automated emails for AASHTO re:source. This contact can be used as a third point of contact or for someone who oversees multiple branches but wants to get more information than what is available through the specifier tools on our website. For more information on specifier tools, please read New Tools for Specifiers: the Missing Piece of the Accreditation Puzzle.

The Shipping, Enrollment, and Billing Contacts have not changed. They will continue to only receive emails pertinent to those specific areas.
Why am I getting an AASHTO re:source invoice?
We send invoices for all three of our programs individually. AASHTO re:source used to send out bills for all services at once, but now it is split out and itemized. These invoices are sent to the billing contact we have on file for your laboratory. If you believe you are getting these invoices in error, please contact us at 240-436-4900 or info@aashtoresource.org.

Invoices by Program:
Invoice numbers that begin with AAP are associated with your involvement in the AASHTO Accreditation Program. When you apply for the AASHTO Accreditation Program, you are invoiced a one-time application fee. The following April, you will receive a bill for AAP which covers the accreditation for the time between your initial application and April. Each year thereafter, you will pay for the previous year’s accreditation. To see a detailed explanation of the billing process, go to the AAP Fees page. If you do not pay your bill, your accreditation will be revoked for the entire scope of the accreditation.

Invoice numbers that begin with PSP are associated with your involvement in the Proficiency Sample Program. In September of every year, you will receive an invoice for the upcoming year’s enrollment subscriptions. If you are new to the program or are adding new samples to an existing enrollment, you will receive an invoice for those samples once your request has been processed. For a breakdown of these fees, please see the PSP Fees page. When laboratories order Extra Proficiency Samples, either to address an accreditation issue or for internal use, a new invoice will be issued. These extra samples will not be shipped until we have received payment.

Invoice numbers beginning with LAP are associated with the Laboratory Assessments Program. When the final report of your assessment is issued, an invoice will also be sent. These invoices are only sent in relationship to an assessor visiting your laboratory. Please visit the LAP Fees page for a detailed list of tests and fees associated with on-site assessments.
