Integrated maintenance model for heavy haul tracks

José João Pires De Oliveira Filho

Due to the accumulation of traffic, the railway components are affected by the induced stresses. As a result, the geometry of the railways is degraded over time. The degradation occurs either through the partial loss of the track's geometry or through the ...

The impact of soil properties on the structural integrity of high-fill reinforced concrete culverts

Liang Sun

Reinforced concrete (RC) culverts under high fill have been widely used in the construction of expressways and railways. Based on the results of a field survey, various types of structural damage to RC culverts occur during construction and service periods ...

Modeling of rutting in asphalt flexible pavement

André-Gilles Dumont

This paper presents a finite element analysis modeling of rutting. The behaviors of the asphalt concrete is described using an elasto-viscoplastic constitutive relation, while an elastoplastic constitutive relation is used for the lower layers. The model a ...

Étude expérimentale du dégel d'un limon argileux : application aux chaussées et pergélisols alpins

Michel Dysli

Curiously, the thawing of frozen soils containing ice lenses has only been the subject of rare fundamental studies even though it is the cause of the greatest damage to constructions. The reduction of bearing capacity caused by the thawing of the ice lense ...

New Method for Pavement Rutting Prediction

André-Gilles Dumont, Mehdi Ould Henia

In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. These solicitations affect the bituminous layers that can quickly attain their permanent deformation limit resistance. This phenomenon can lead ...

Predictive method for evaluation of pavement rutting

André-Gilles Dumont, Mehdi Ould Henia

Pavement rutting not only decreases the road service life but also creates a danger for the security of road users. In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. It is well known that the in ...
