The Kansas City Metro Materials Board (KCMMB) is a cooperative effort of public works organizations in the KC Metro area. The goal of KCMMB is to propose standardized material specifications for durable concrete and asphalt on members' public works projects and to simplify the approval process with the assistance of this web site.

Please select either "Portland Cement Concrete" or "Asphaltic Concrete" above to get started.

KCMMB specifies general purpose concrete and asphalt. Always check the job specific specifications.
