Pavement Operations - 591-0310-17

Description of Agency/Program/System

The Michigan Department of Transportation (MDOT) is responsible for Michigan’s 9,669-mile State highway system, comprised of all M, I, and US routes. MDOT’s 7 region offices determine pavement material for projects where pavement costs are estimated to be less than $1.5 million. For those projects where pavement costs are estimated to exceed $1.5 million, the Pavement Operations Division peforms a life cycle cost analysis (LCCA) to determine the most cost-effective pavement materials. The Pavement Operations Division operates three labs (aggregate, concrete, and asphalt) that test supplier materials to ensure that they meet MDOT specifications prior to their use on an MDOT project. The 7 regions and 25 transportation service centers test materials throughout the projects to ensure that the materials continue to meet specifications.

The Pavement Operations Division administers the Pavement Demonstration Program. This Program allows MDOT to test new materials and new methods of utilizing existing materials that will increase pavement life and decrease pavement costs.

Audit Objectives

  1. To assess the effectiveness of MDOT’s efforts to ensure that pavement material used meets specifications.

  2. To assess the effectiveness of MDOT’s pavement type selection process.

  3. To assess the sufficiency of MDOT’s efforts to manage the Pavement Demonstration Program.
