The Michigan Department of Transportation’s specifications for capital preventive maintenance are developed through the cooperative efforts of the Pavement Preservation Operations Committee (P2OC).

Specifications describe the nature of work to be complete, materials to be used, and construction processes to be followed.  They are important to the execution of a project because they serve as a basis for common understanding of the charges between the contractor and the agency and the process that the contractor will follow when completing the project.

Clearly specifications serve an important purpose, but they are not rigid. Preconstruction meetings between the contractor and agency can be used to make special arrangement that will improve an individual project’s process or performance. This communication is an important component to ensure quality jobs with minimal disruption for the motoring public.

What is the P2OC?

The P2OC is co-chaired by the MDOT Engineer of Construction Field Services and the MRPA Executive Vice President and includes representation from MDOT and industry. The group is responsible for pavement preservation specifications, technical issues related to pavement preservation, and evaluation of new product and method innovations. While it’s charge may be technical, its focus is continual quality process control at all stages of CPM projects.  To learn more, click here to review the P2OC Guidance Document.
