  • Evaluation and Limitation of Impacts social and environmental for Road Networks and Transport Policies

    One work area of the PIARC Committee 14 on "Sustainable development and Road Transport" concerns the evaluation and limitation of impacts of road networks and transport policies. The Road is life (Via Vita). This are the words contained in the logo of the World Road Association established in 1909. [...]

  • Evaluation and maintenance of concrete pavements

    The road asset of a country or region is of considerable value. Owners who have chosen to invest in concrete pavements for all or part of their road network or their airfields have often done so hoping to obtain a lasting infrastructure and a guarantee of maintaining traffic in all weather conditions.

  • Flexible Pavement - Evolution of Specifications and Quality Systems to Deliver Performance

    Specifications for bituminous materials in highway construction are continuously evolving. At an early stage, they were more intuitive and based on engineering judgement. They were called method or recipe specifications in which the client specified the materials and procedures that the contractor had [...]
