The Economic Value of Pavement Overlay Alternatives

The majority of the US highway roadway system has been completed for many years, thus requiring agency resources to be focused on maintaining and rehabilitating existing pavements. Economic analysis of pavements must consider initial costs, design life, maintenance costs over the life of the pavement and salvage value at the end of its life-cycle. This case study examines five pavement rehabilitation methods for asphalt roadways using equivalent 20-year pavement overlay designs in contrast to the 40-year life cycle designs traditionally used for new construction and full-depth reconstruction. These designs will be judged under the scrutiny of the economic value of the pavement from the beginning to the end of the 20-year pavement life-cycle.
