PIARC (World Road Association), founded in 1909 and comprising 125 member governments from all over the world, is the global forum for exchange of knowledge and experience on roads, road transport policies and practices. With consultative status to the Economic and Social Council of the United Nations, the Association is contributing to a stable and sustainable global development of the road and transport sector.

  • International Symposium on Subdrainage in Roadway Pavements and Subgrades

    Out of print As is common knowledge in the transportation community, proper functioning of roadways is largely dependent on adequate drainage, both at the surface and in the subsurface. The accumulation of excessive water under pavements typically results in a reduced bearing capacity, leading to [...]

  • Porous Asphalt

    For about ten years, the use of porous asphalt has grown rapidly in some countries where the material is used for a large part in road surface maintenance works on highly trafficked roads. Some countries even impose porous asphalt on motorways beyond a certain level of traffic. On the other hand, some [...]

  • The Use of Roller Compacted Concrete for Roads

    Regarding its use for pavements, roller compacted concrete (RCC), could be considered as a hybrid between cement treated granular material and vibrated concrete. Indeed, RCC pavements can carry traffic directly on the finished surface, a possibility not offered by cement treated bases. Its simple [...]
