Technical Reports Earthworks

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

  • Road in Desert Areas

    Drafted by the PIARC Technical Committee on Roads in Developing Regions, this report provides information on the construction and maintenance of roads in desert areas.

  • Equipment and Methods Specific to Soil Treatment Works

    To avoid the report on "Field treatment of soils with lime or hydraulic or pozzolanic binders" presented at the XIXth World Road Congress at Marrakech in 1991 (PIARC ref. 19.12.B), being too long, the Technical Committee on Earthworks, Drainage, Subgrade (C12) decided to limit the discussion of equipment and methods for stabilization to a simple listing. However, aware of the decisive practical impact of these points upon the quality of soil treatment works, C12 has decided to complete the report [...]

  • Contribution to Risk Management of Existing Slopes

    C12 decided to extend those studies and adopted the topic risk management of existing slopes during the period 1995-1999 to focus on the utilization of monitoring techniques and database applications. The report summarizes the risk management on existing slopes in technical aspects through the collected case study documents and comments from C12 committee member countries. The report also treats the cases of real and administrative applications. The report considers innovative monitoring technology [...]

  • Slope Risk Guidance for Roads

    Slopes are, in general, associated with a greater frequency of failure than other geotechnical assets and a greater threat economically and socially. This report makes a synthesis of risk analysis methods and of vulnerability issues. It presents, in a series of appendices, mitigation measures with their advantages and disadvantages together with a set of case studies.

  • Landslides - Techniques of Evaluating Hazard

    This report discusses current techniques used to evaluate landslide hazard in three stages. Firstly, the landslide hazard of an area is evaluated by collecting existing data, field reconnaissance, etc. At several specified sites along a route, more detailed investigations are then conducted, such as geophysical exploration, borings and stability analyses. The results are used to evaluate the landslide hazard at the sites more precisely and to design works to prevent possible landslides. [...]
