Fatigue Testing of Railway Tracks with Asphalt Pavement

Project Partners :

Objectives

The objective of this project is to increase the clearance gauge of existing tunnels at a lower cost and with minimal disruption. Railway tracks traditionally consist of an infrastructure layer (earthworks) and a superstructure (ballast, sleepers and rails, supplemented where necessary by track components). The proposed solution involves removing the ballast and sleepers (50 cm thick) and replacing them with an innovative continuous rail support system on a bituminous-bound granular structure. This solution offers the advantages of cost-effective installation, a short curing time and good long-term durability.

Loading Prototype

To carry out testing on asphalt mixtures, a new loading prototype was developed by the SII laboratory. :

Ongoing Tests

The tests are ongoing: approximately 700,000 cycles have been completed out of the one million expected.
