PAVEMENT SIMULATION TOOL TO FACILITATE TRANSPORTATION DECISIONS

Within this research, the term "simulation" refers to computer models that can simulate complex systems by stepping through discrete points in time. These models are especially useful for investigating dynamic systems involving multiple, interdependent variables. For this reason, they are particularly useful for pavement engineering. The U.S. Army Engineer Research and Development Center is developing software that will serve as a decision-support tool for field engineers as they anticipate pavement deterioration in order to select transportation routes and schedule the material necessary to sustain operations. This paper describes the theory and the components of the pavement engineering simulation model, which accumulates damage for a pavement as traffic is applied over time and presents results in a manner that is conducive to reliability concepts. Currently, the model is an early version of what will be a useful tool for conducting sensitivity studies and for quantifying the functional and structural reliability of pavements.
