Guided Public Transport Infrastructures Contribution of Cement Concrete in Innovative Designs

Paper by CHRISTORY GRIN DEPETRINI from ISCR 10th 2006 Brussels Belgium

Recent years have witnessed the significant development of public surface transport systems: in our cities: tramways, systems on tyres, right-of-way bus corridors, etc. This phenomenon is a response to the high stakes involved for mobility and communication in urban areas. These projects have seen the emergence of new problematics related to the necessary coexistence of techniques previously foreign to each other: highway and railway engineering. In connection with Operational Group 10 (Vehicles and Infrastructures: Integrated Developments) of the PREDIT Programme (French acronym for Programme for Research and Innovation in Land Transport), a group of 17 partners from various fields met to reflect on rail/surfacing interfaces around the INDUIT Project (French acronym for Sustainable and Integrated Infrastructures for Public Surface Transport). This project seeks to achieve the following four objectives: 1. Capitalising on knowledge relative to surface public transport infrastructures. 2. Initiating the reflex of joint working between hitherto compartmented trades. 3. Embracement of research findings and problematics, in the form of real-time instructions for action by all professional players. 4. Prospects with regard to innovative solutions. Regarding the latter point, and in particular as concerns concrete products and materials, the reflection covers mainly the problems of discontinuity, drainage, and worksite execution and organisation.
