    One of the main missions of the Laboratoire Central des Ponts et Chaussées in Nantes (LCPC) has been the improvement of the quality of repaired pavements. The major problem observed is the frequent incidence of reflective cracking over the top asphalted new layer. One experiment has been adapted then to evaluate this kind of damage on a small track in a full scale test using an Accelerated Pavement Testing (APT) machine. The experience made with this APT is the next step in the development of a…

    One of the main missions of the Laboratoire Central des Ponts et Chaussées in Nantes (LCPC) has been the improvement of the quality of repaired pavements. The major problem observed is the frequent incidence of reflective cracking over the top asphalted new layer. One experiment has been adapted then to evaluate this kind of damage on a small track in a full scale test using an Accelerated Pavement Testing (APT) machine. The experience made with this APT is the next step in the development of a new laboratory equipment to evaluate the behaviour of bituminous layers confronted to reflective cracking damage mechanisms. A large amount of sensors measure deformations, temperature, displacements and crack evolution. The experimental data has been compared with numerical calculations made with the CESAR-LCPC’s FEA software. This comparison had lead into validation of hypothesis and into a better comprehension of the reflective cracking failure mechanism reproduced with the APT equipment.

    During this course I had the possibility to assist to the whole cursus during 8 months concerning all the explanations of urban project management. Planning, executing, monitoring and controlling, and closing. All supported by architects, lawers and engineers which were our profesors. The frame of the course was always the urban french environment, explaning in detail the legislation, the processes and methods used in France.

    La compétence particulière visée est la modélisation micromécanique, à partir des propriétés
    de leurs constituants, des matériaux et des éléments structurels qui résultent d'un assemblage
    de plusieurs constituants, dont la taille est petite devant l'échelle macroscopique. Il en est ainsi
    des matériaux et des ouvrages du Génie Civil, des matériaux et des éléments structuraux des
    structures mécaniques de l'industrie, du génie mécanique, etc. Citons par exemple, les
    matériaux cimentaires, les sols saturés d'eau, les structures composites multicouches , les «géocomposites» : sols renforcés, béton armé, etc.

    The various components of an inductive power transfer system need to be embedded in a precise position and geometry for efficient inductive power transfer. These compo-nents need to be arranged so that the electrical components carry out their intended in-ductive power transfer function and provide a road surface for vehicles to travel on. The material of the pavement needs to protect the electrical components from the traffic loading and environmental conditions and also be durable for its function as a road. The problem is solved by installing these components make up a power transfer system in a precast pavement slab which typically would be constructed from concrete.
    The invention has the following advantages:
    -allows the precise fabrication of the inductive power transfer system in a controlled envi-ronment .
    -the fabrication will not be adversely affect by bad weather and unprecise work which is typical of insitu workmanship.
    -ensures quality checks can be carried out on inductive power transfer system compo-nents and pavement.
    -allow a series production of the system.
    -precast slabs allow rapid onsite installation.
    -minimises disruption to traffic flow and road closure duration with rapid installation .
    -ensures a monolithic pavement structure with a single application of the pavement ma-terial surrounding the components for greater slab durablity and service life.
    -precast system can be fabricated in factories in accordance with system specification and instructions around the world.
    -precast inductive charging pavement slab can be delivered to the installation site with a truck and lifted into place for immediate comissioning and operation.

    Proctect and hold electronic devices to be implemented in the surface of a heavy loaded road. More specifically, for inductive systems to recharge electric vehicles it is neces-sary to detect metals. An electronic device placed on the pavement will have difficulties in surviving the heavy loads expected on the road.

    Proctect and hold electronic devices to be implemented in the surface of a heavy loaded road. More specifically, for inductive systems to recharge electric vehicles it is neces-sary to detect metals. An electronic device placed on the pavement will have difficulties in surviving the heavy loads expected on the road. As the Metal Object Detection (MOD) device has been developped in Bombardier, a solution to install properly this device on the surface of the road is presented. This solution will have the advantage that it will be possible to roll over the system with all types of vehicles, and most particularly heavy loaded vehicles. The device detecting the metal will be protected and its service life can be ensured with this invention.

  • Snow melting system for heavy load traffic roads providing inductive electrical charging to vehicles

    Europe

    Control, reduce and melt the snow over thick rolling surface layers providing support to heavy loaded vehicles and allow them to be electrically charged if needed. In cold sea-sons and/or cold regions, and whenever a perfectly flat rolling surface is needed, an automatic snow melting system integrated on a road will provide the solution to ensure electrical power transfer to electrical vehicles. The invention solves the problem for the whole time of the snow falling and can be used in pavement…
