Transport and Covid-19: responses and resources

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.

Policy Insights

  • Long-life surfacing is essential for advanced and affordable transport infrastructure.
  • The higher cost of long-life road surfacing materials is justified particularly for road network hot spots.
  • It will be important to continue monitoring existing test sections in the future to corroborate findings over the road pavement life cycle.
