Coarse Aggregate Initial Approval


The KCMMB requires all coarse aggregates be initially approved prior to use in KCMMB concrete. The following outlines the approval process and requirements:

After initial approval, the coarse aggregate must meet the requirements outlined in the current specification each year.

All required information must be submitted a minimum of 30 days before the next regularly scheduled meeting of the Board to be considered in that meeting. Submittals not meeting the 30-day requirement will be added to the agenda at the Agent's discretion. Incomplete submittals will not be reviewed by the Board

Care should be taken to communicate with the Agent before the deadline to address any questions regarding this document.  

The current KCMMB specification should be reviewed prior to submittal to verify material testing data meets the requirements of the specification.
