The Innocuous Aggregate Prequalification Program establishes procedures to ensure that aggregate meets the requirement of Section 90-1.02C (Aggregate) in Caltrans’ Standard Specifications, that both the fine and coarse aggregate must be on the Authorized Materials List (AML) for the aggregate used in concrete to be considered innocuous.
Application Procedures and Materials Requirements
Before the aggregate is sampled for testing, the aggregate shall be registered with the Department. A registration number can be obtained by contacting Francisco Romero, Francisco.Romero@dot.ca.gov, and that registration number shall be used as the identification for the aggregate sample in correspondence with the Department.
The Supplier shall provide the following information to Caltrans when applying for the registration number:
The supplier shall follow the procedures in below for sampling aggregate in alkali silica reactivity tests:
Upon request, a split of each tested sample should be sent to the following address:
Attention: Francisco Romero,
Innocuous Aggregate AML Program
5900 Folsom Blvd, Sacramento, CA, 95819-4612
All submittals to the Department are required to include a label with the registration number, pit name, and size of the aggregate. It is mandatory to notify Caltrans of any changed ownership, or any other changes occurring with your SMARA number, within 30 days of the change.
Authorization of aggregate will depend upon compliance with the specifications, based on the test results from an accredited testing laboratory, and the results of any verification testing the Department may elect to perform. Authorization will expire in 5 years from the collection date of the most recent authorized sample from the source.
Innocuous aggregates shall conform to one of the following:
Qualified testing laboratories performing ASTM C1293 or ASTM C1260 for aggregates shall conform to the following requirement:
Have a current AASHTO accreditation for ASTM C1293.
Have a current AASHTO accreditation for ASTM C1260.
Note: Effective July 1st, 2020, Caltrans will only accept test results from AASHTO accredited labs certified for the test performed for the Innocuous Aggregate AML Program.
The Department may inspect, sample, and test materials for compliance with the Contract at any time. Allow the Department to record, including photograph and video, to ensure a material is produced to comply with the Contract. You may examine the records and reports of tests the Department performs. Schedule work to allow time for the Department's inspection, sampling, and testing. The Department deducts testing costs for work that does not comply with the Contract. The Department may retest material previously tested and authorized for use. If the Department notifies you of a retest, furnish resources for retesting. Additionally, the supplier needs to notify the independent lab that Caltrans may contact them regarding any information about the ASR testing which they have performed.
