Fatigue and Moisture Damage Resistance of Bituminous Mixtures for Railway Trackbeds
This paper focuses on the fatigue resistance properties and susceptibility to moisture damage of different bituminous mixtures used as sub-ballast layers in French railways. The analysis is made taking into account the specific working conditions and service life requirements of trackbeds. Three different road base-course mixtures used as sub-ballast layers in France were studied. A new moisture-conditioning procedure was proposed and used to induce moisture damage in the samples. Tension-compression fatigue tests were carried out on cylindrical samples at the Laboratory of Civil Engineering and Construction (LGCB) of the ENTPE, University of Lyon. All the tested mixtures were found to present satisfactory fatigue resistance properties. Low voids content and the use of polymer-modified bitumen were found to improve the resistance to moisture damage.
