Economic Evaluation of Long-Life Pavements

Phase 1

image of Economic Evaluation of Long-Life Pavements

With maintenance costs accounting for a large proportion of road budgets, this report assesses the economic and technical feasibility of innovative wearing courses for long life road pavements. While having higher initial costs, such wearing courses have the potential to dramatically reduce recurrent road maintenance requirements and user costs and could also reduce overall costs significantly, under circumstances outlined in the report.

Economic Feasibility of Long-life Pavement Surfacing

This chapter contains an analysis of the economic feasibility of advanced pavement surfacings. The analysis shows that in certain situations, advanced wearing courses with higher initial costs are justified. The longer life of the surfacing and associated reduction in maintenance costs over its lifetime compensates for the higher initial costs.
