Effect of base bitumen composition on asphalt rubber binder properties

André-Gilles Dumont, Mehdi Ould Henia

The asphalt rubber blend properties are strongly related to its base components properties. The base bitumen composition is considered as a key factor influencing the final rheological properties of asphalt rubber binder. This paper describes results from ...

Cluster phenomenon and partial differential aging in RAP mixtures

André-Gilles Dumont, Sara Bressi, Michel Pittet

The present study defines a procedure for gaining a better understanding of the interaction between the aged and the virgin binders and what actually occurs during a mix process. Indeed, the authors propose a methodology to determine and quantify the clust ...

Dynamics of Lane Distribution Flows in Freeways

Nikolaos Geroliminis, André-Gilles Dumont, Sofia Samoili

Lane density and lane flow distribution are utilised in the current study as characteristics of traffic dynamics for control and planning purposes in freeways with ITS systems. As part of an on-going research, the Lane Flow Distribution Ratio (LFDR) and th ...

Random Forest Models for Identifying Motorway Rear-End Crash Risks Using Disaggregate Traffic Data and Meteorological Information

André-Gilles Dumont, Ashish Bhaskar, Minh Hai Pham

This paper presents an approach to develop motorway Rear-End Crash Risk Identification Models (RECRIM) using disaggregate traffic data, meteorological data and crash database for a study site at a two-lane-per-direction section on Swiss right-hand driving ...

Self supplied navigation systems: microsimulation-based performance assessment

André-Gilles Dumont

The self-supplied navigation concept is based on the combination of the floating car data technique and the dynamic route guidance service in the same vehicles. The gains obtained by the users of such system are, obviously, closely related to the percentag ...

A Multi-Dimensional Analysis of Hard Shoulder Running Systems

André-Gilles Dumont, Dimitrios Efthymiou, Sofia Samoili

The use of Hard Shoulder Running (HSR) systems is a relatively recent control policy aiming to ameliorate traffic conditions in recurrent congested networks. This ITS strategy attracts researchers and practitioners interest, in an attempt to assess its imp ...

Deriving a load model for the braking force on road bridges: Comparison between a deterministic and a probabilistic approach

Katrin Beyer, André-Gilles Dumont, Marc-Antoine Fénart

The current provisions for the braking force in the Eurocodes are much more demanding than previously enforced national codes from most European countries. Hence, safety assessments of existing bridges may show a lack of compliance with the new safety requ ...
