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 ...
This communication concerns analysis of the behavior of flexible pavements using an elastic-viscoplastic constitutive relation for the asphalt concrete. The numerical model takes into consideration the influence of the temperature on the behavior of the as ...
Currently, estimations of the crack width in the deck slab of bridges given by codes of practice are based on either theoretical or empirical approaches considering mainly the monotonic loading behaviour. However, cracking in reinforced tensile members is ...
The main objective of this innovation is to develop bituminous underlayers (sometimes called base course) with high percentage of re-use materials at low cost and with high performance. In fact, this innovation concerns the formulation and assessment of hi ...
Ultra high performance concretes (UHPFRC) are characterized by a dense matrix and a high fibre content. These materials exhibit exceptional mechanical and durability properties making them an ideal material for rehabilitating existing structures. The prima ...
This paper presents a new concept for a lightweight hybrid- FRP bridge deck. The sandwich construction consists of three layers: a fiber-reinforced polymer composite (FRP) sheet with T-upstands for the tensile skin, lightweight concrete (LC) for the core a ...
This Phase 2 Report demostrates that the technology available for long life semi-rigid pavements is not as developed as that for fully-flexible pavement types. Whereas the concept of long-life fully-flexible pavements has been adopted in some European pave ...
Hybrid slab systems combining fiber-reinforced polymer (FRP) composites with concrete are promising load-bearing structures, and an increasing number of applications has demonstrated their high potential in terms of structural performance and durability. H ...
New Road Construction Concepts (NR2C) is a FEHRL- project supported by the European Commission under the Sixth Framework Programme. NR2C aims at developing perspectives and specific innovations in different areas. One of the ideas concerns the development ...
As explained in previous "Vision 2040" report, NR2C project deals with the perception of the road infrastructure in the future by considering the point of view of different type of people. Following this general idea, different research strands have been a ...
