CONSTRUCTION OF ROADS ON COMPRESSIBLE SOILS

The report is the result of a study carried out in 1977 and 1978 on the construction methods for roads on weak compressible soils such as clays, silts and peats. Experts from 16 OECD member countries participated to review the international state-of-the-art in this field which is gaining in prominence due to the economic, environmental and energy constraints of modern road design and construction. In addition to reviewing the methods of site investigation, soil testing, stability and settlement analyses the report gives comprehensive details of methods of treating soft soils to improve the foundation properties, outlines the techniques of instrumentation currently employed, and briefly describes some of the problems which may arise during construction. Several case histories relating to embankment instability are also described. The report ends with a list of conclusions and recommendations as well as future research needs. (a) (TRRL)
