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.

Next-generation Pavements for High-traffic Highways

This chapter examines a number of different wearing courses that have been developed to withstand high loading with minimal maintenance. These are generally used for smallscale projects and may not yet be suitable for mainstream use. Two materials are considered to have developmental potential to produce long-life wearing courses and are recommended for further examination.
