Il s'avère aujourd'hui important de développer de nouvelles techniques de maintenance en accord avec les principes du développement durable. Dans ce sens, la récupération de matériaux bitumineux issus de la réfection d'anciennes chaussées peut contribuer à ...
In anticipation of the introduction of high modulus materials in the Swiss standards, a research project has been carried out for the evaluation of these bituminous mixtures. Three full-size test sections were built in a test hall for ALT named Halle-fosse ...
During the last 20 years, backscattered electron imaging of polished surfaces has become well established as a method for the study of cement and concrete microstructures. The technique has many advantages, including the visualisation of representative cro ...
In anticipation of the introduction of high modulus materials in the Swiss standards, a research project has been carried out for the evaluation of these bituminous mixtures. These mixtures make possible to reduce rut in base courses. With a temperature of ...
In the field of ITS applications evaluation, micro- simulation is becoming more and more a useful and powerful tool. In the evaluation process, one of the most important steps is the safety analysis. For that purpose, classical micro- simulation outputs gi ...
In creating Terms of Reference, the Group has to consider the scope of the meaning of long-life pavements. It is suggested that this should not be ‘life’ related but based on the concept that a long-life pavement is one that is heavily trafficked, and is d ...
Ultra-High Performance Fibre-Reinforced Concretes (UHPFRC) have high mechanical strengths (fU,c > 150 MPa, fU,t > 6 MPa) and exhibit quasi-strain hardening in tension. Their very low permeability prevents the ingress of detrimental substances. In composite ...
Two main factors govern the ingress of chloride ions into concrete reinforced with ordinary steel reinforcement, from de-icing salts: (1) the cover concrete (permeability, thickness), and (2) the microclimatic conditions (humidity, temperature, concentrati ...
The objective of the task managed by Working Group 2 is to set up an inventory of maintenances schemes and procedures currently applied in the organisation of pavement maintenance on some major road networks in Europe. ...
Temperature variations are particularly harmful to wearing courses with asphalt mixture. During wintertime, and especially, at very low temperatures, a surface cracking may appear and propagate more or less rapidly. An experimental investigation has been c ...
