    Generating Infrastructure Funds Through Innovative Pavement Management
    Ponce, Javier; Overton, Patrick; Cunagin, Wiley (2015-06-04)
    The American Society of Civil Engineers (ASCE) estimates that there will be a need for $3.6 trillion in infrastructure investment by 2020. A portion of this need can be made available through judicious management of the Nation's pavement systems. The Florida Department of Transportation (FDOT) has made significant progress in meeting this objective by continuously improving the performance of its materials, processes, construction methods and management, and pavement management technology. One notable innovation of this effort has been the adaptation of survival analysis through intensive collection and analysis of longitudinal pavement performance data. The methodology allows the projection of the performance of new materials and technology even before significant evidence of pavement distress is apparent. This approach has been applied to pavement ratings for Open Graded Friction Course (OGFC) and Dense Graded Friction Course (DGFC) mix designs as well as Florida FC-2 subclasses of OGFC and Marshall and Superpave subclasses of DGFC. As a result, by incorporating this knowledge into predictive algorithms FDOT has been able to reallocate approximately $3 billion in nonessential resurfacing funds to other infrastructure needs over the next ten years.
