Welcome on piarc.org!

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.

Technical Reports Road pavements

This page lists technical reports of PIARC in the field of Road pavements. These publications are classified chronologically.

  • Inventory of Surface Characteristics Measuring Equipment

    In 1989, the PIARC Technical Committee C1 started compiling an inventory of surface characteristics measuring equipment used throughout the world. The result is a comprehensive listing of equipment for measuring longitudinal evenness, transverse profile distresses (rutting), texture and skid resistance (tire-pavement friction) of pavements, the deformation of road surfaces. The information is presented as tables (one table per device) which composed a bilingual catalogue (English - French). [...]

  • Testing of Marginal Materials

    Drafted by the PIARC Technical Committee on Testing of Road Materials, this report is a direct extension of the first PIARC publication on Marginal Materials (see page 57). The first part examines the conventional tests applied to some marginal materials of the industrial by-product type and sets out the conditions to be achieved to obtain a certain international harmonization. The second part is devoted to special tests and completes, further specifies or corrects data appearing in the first publication. [...]

  • Marginal Materials - State of the art

    Three PIARC Technical Committees have devoted part of their preliminary work to the XVIIIth Congress (Brussels, 1987) to the use of marginal materials in road technology: Technical Committee on Testing of Road Materials, Technical Committee on Flexible Roads, Technical Committee on Earthworks, Drainage, Subgrade. The first part of the document concerns the use of marginal materials in earthworks and subgrade. The second part deals with the use of marginal materials in the construction of flexible [...]
