Petit, I. Al-Qadi and A. Millien ISBN: Pages: Publication date: The preservation of the patrimony that represents the road network is a challenge for our modern societies. Developing efficient construction methods able to guarantee long life structures without spoiling natural resources and destroying the environment is more than ever, a major requirement nowadays.

The following distinguished scientists have agreed to give lectures at MCD His research covered a wide range of topics such as cracking of asphalt pavements, behavior of unbound materials, pavement evaluation and accelerated pavement testing.

Next to that he acted and still acts as senior advisor to some major design and construction projects in and outside Europe. Since then a huge amount of research was done on the prediction of defect types like permanent deformation, raveling, cracking etc. If this is not the case we have to define the problems that still need to be solved and what kind of research is needed to arrive to these solutions. The presentation will start with a short overview of the cracking research history and how the results are implemented in design systems.

Ample attention will be given to material characterization and test methods which will result in some statements with respect to preferred test methods some may be provocative. This includes a critical review of some European norms.

Based on this some proposals with respect to future research will be made. Finally a number of construction aspects will be discussed which heavily influence pavement performance. Glaucio H. His special interests focus on mechanical and physical properties and characterization of bituminous materials and systems. It has not only major impact on durability and mechanical performance of asphalt pavements but also on structural damage of concrete bridge or tunnel decks with bituminous overlays.

The reason why it has been neglected for many years, is possibly due to the fact that debonding is not only a materials issue but a phenomenon that is affected by the whole structural system. It is therefore heavily influenced by a great variety of undefinite parameters depending on techniques and field conditions of construction, thus creating quite a bit of challenge for assessing debonding from a laboratory point of view.

This presentation deals with several phenomena of debonding such as interlayer shear behavior between asphalt pavement layers under different conditions and pavement configurations. It provides an overview on recent own research on characterization of adhesion of pavement joints and asphalt pavement plug joints as well as on understanding phenomena of blister formation on bridge decks waterproofing systems. Measurement methods for detecting debonding and blistering are considered and possibilities of artificial healing of debonding are addressed.

In , he received the silver medal from CNRS. It belongs to the family of the non-local damage models and thus introduces a length. The originality in the TLS is that it incorporates a geometrical aspect : the shape of the localization zone is located by a level set. So far, most of the efforts have been concentrated to quasi-brittle fracture. After restating the motivations for the new model, we review the results obtained in these past 5 years.

The following issues will be addressed : Capability of the model to reproduce properly size effects in concrete cracking; Predictive capabilities for crack onsets at notches; Capability of the model to take into account concurrent local and non-local developments of damage; Comparison with other non-local damage models; Relationships with the cohesive zone model.

Finally, a set of open issues will be detailed. At the CSIR, he is a Principal Research and Professional Engineer active in the areas of flexible and rigid road pavement materials, new and rehabilitation design and analysis methods of road pavements.

During the last 10 years, he focussed primarily on tyre-pavement interaction with the locally developed tyre-road pavement Stress-In-Motion SIM system. This led to improved mechanistic-empirical ME design and evaluation methodologies, including slip between layers. On the recycled material side developments resulted in an advanced laboratory twin-shaft pugmill mixer technology, currently available in practice.

It is based on viewing and analysing pavements as structural systems which respond to traffic and environmental loading influences. Henrique M. His research areas include materials characterization, structural health monitoring, and life-cycle management of materials and structures. The approach, which is based upon nonlinear ultrasonic interrogation of the pavement top material layer, consists in analyzing the resultant wave field of the non-collinear mixing of two critically refracted longitudinal ultrasonic waves.

This curve, which is AC-mixture-dependent only, serves as the calibration curve that allows pavement prognosis by nonlinear ultrasonic measurements at the pavement surface. The use of this approach in pavement engineering to assess the self-healing capacity of pavements and to evaluate maintenance treatments on asphalt pavement surfaces, such as the use of penetrating rejuvenators is discussed.

7th RILEM International Conference on Cracking in Pavements

This conference has been hosted by the French Institute of Science and Technology for Transport, development and network Ifsttar. Some presentations coming from the 4 MCD workshops are available and may be downloaded here. Following MCD, based on both the quality of the 6-page short paper published in the Springer proceedings See here the Springer Self-archiving policy and the quality of the presentation as evaluated by the designated session chair, 21 extended version have been finally accepted in thematic issues of the 3 journals: RMPD Vol. This multilayer system rests on a semi-infinite soil and is subjected to severe climate variations and heavy traffic loads. In their lifetime, pavements undergo degradation due to different mechanisms of which cracking is among the most important.
