  • Life-cycle Cost - Asphalt Pavement

    Life-cycle Cost. Life-cycle cost analysis is one of the tools by which pavement structures are evaluated and eventually selected by pavement owners. The life-cycle cost of a road includes the money spent on initial construction of a road, maintenance over its lifetime, and the costs to users for their delays during maintenance and reconstruction.


    ASPHALT PAVEMENT LIFE CYCLE. As pavement progresses through its 20 year, average performance life cycle, it changes along the way. Its appearance and functionality diminish over time. This aging process begins immediately after construction even though these early changes are impossible to see.

  • ECONOMICS - Asphalt Pavement Alliance

    Good stewardship practices include a detailed, logical, and documented pavement type selection process that includes a life-cycle cost analysis as a key component. Pavement Type Selection - PTS. Pavement type selection, or PTS, is the process that identifies the best pavement structure for a given application.
