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.



Epoxy-asphalt road surfacing field trials

This chapter describes the findings of the third phase of this project (i.e. the field trials) in respect to the epoxy-asphalt materials tested. Three test sections using epoxy asphalt were built and monitored: two in epoxy-modified open graded porous asphalt, in New-Zealand, and the third one in stone-mastic asphalt, in the United Kingdom. No significant difficulties were encountered during the construction phase, and the two pavements have exhibited to date satisfactory behaviour under service.
