Abstract:

In the summer of 1986 the Illinois Department of Transportation (IDOT) built four demonstration sections to validate the proposed mechanistically-based pavement design procedures. Multiple variables were taken into consideration in order to determine a valid correlation between pavement design inputs and pavement performance. After 25 years of service, these sections have provided great value to IDOT in the development of the pavement design procedures, policies and standards, and in general a better understanding of the mechanics of pavement performance. The knowledge acquired from the four sections supports IDOT’s practice in the use of performance graded binders, joint spacing in jointed concrete pavements, jointed concrete and full-depth hot-mix asphalt pavement thickness design, and subgrade selection. This study has validated IDOT’s mechanistic pavement design procedure, proving that the theory behind the 1986 design was correct. Since then, these sections and extensive laboratory testing and investigation have allowed IDOT to further refine the mechanistic pavement design procedure to include more accurate material properties. In addition to improving design procedure, having 25 years of data and observing the deterioration and rehabilitation of certain sections have allowed IDOT to fine tune the maintenance models to improve pavement type selection between flexible and rigid alternatives.
