Long-life Surfacings for Roads

Field Test Results

This report is the third and final output of a ten-year international research project studying the costs and viability of long-life road pavement surfacings. It describes the results of tests conducted with epoxy asphalt and high performance cementitious materials (HPCM) on real road sections in France, New Zealand and the United Kingdom. The project was initiated to address a growing problem for road administrations and road users: frequent closures of roadways for repairs and repaving as a result of surface pavements that have improved but still barely kept up with increased loads and traffic density.



Executive summary

International Transport Forum

Maintenance of high-traffic roads is expensive, and has indirect social costs that are less and less acceptable in the context of traffic gridlock in big cities. Therefore, a shift from low cost, low durability maintenance techniques to more durable and more expensive ones is desirable for the sake of the common interest. The long-life pavement (LLP) project launched by the ITF in 2002 addressed these issues in a series of three reports of which this is the final one.
