The purpose of the TCP is to ensure the quality of materials incorporated into MoDOT projects
by supporting proper and uniform procedures among individuals responsible for the sampling
and acceptance testing (including IAS and FAST) of certain non-manufactured materials used in
transportation construction projects. These materials are aggregates, soil, concrete and asphalt.

All technicians who perform, or are required by the FHWA to witness, such sampling and testing
shall be deemed as qualified by virtue of successfully completing the requirements of the TCP
for that specific technical area. They will be identified by a certification card issued by the
certifying authority. The card will note the expiration date and each certification level. Any
individual who has not been qualified is not eligible to perform these functions on MoDOT
projects on the National Highway System.
