PIARC XVII WORLD ROAD CONGRESS, SYDNEY, AUSTRALIA, OCTOBER 8-15 1983. QUESTION I: EARTHWORKS, DRAINAGE, SUBGRADE. GENERAL REPORT

This general report examines the national reports on: (a) earthwowrks (site investigation, foundations of embankments on compressible soils, embankments, slopes, carrying out earthworks), (b) drainage, (c) subgrade, and (d) inspection and maintenance of earthworks. The innovations reported since the last congress are summarised, and attention is drawn to the progress made and points that should be considered to be established fact. Unresolved problems are listed together with topics for desirable research. The subjects proposed for discussion at the congress are outlined: 1. Optimisation of site exploration programmes; 2. Influence of equipment developments on the specifications for unstable materials compaction; 3. Available experience on the use of recommendations for embankment compaction and on continuous control methods; 4. Practical methods for the prediction of and protection against rock falls; and 5. Means to improve economic and regular inspection and maintenance of drainage systems. (TRRL)
