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.

Field trials with high-performance cementitious materials

International Transport Forum

High-performance cementitious materials (HPCM) is an innovative technique that was elaborated during the previous phase of the project. This chapter summarises the results of the field tests conducted in France and further testing conducted in the United Kingdom regarding large-scale mixing and pumping equipment and laying. The material seems promising, but requires further refinement to reach the project goal in terms of durability in real conditions.
