WRITTEN DISCUSSION: CONSTRUCTION OF DAMS, ROADS, AIRFIELDS, HARBOURS, LAND RECLAMATION IN OR ON TROPICAL SOILS. GEOMECHANICS IN TROPICAL SOILS. PROCEEDINGS OF THE SECOND INTERNATIONAL CONFERENCE ON GEOMECHANICS IN TROPICAL SOILS, SINGAPORE, 12-14 DECEMBER 1988. VOLUME 2

In this paper, it is proposed that the conventional method of evaluating and controlling soil compaction, utilizing optimum water content and maximum dry density is not suitable for residual soils. Alternative methods of compaction control are widely used in New Zealand and on highway, earth dam and geothermal projects in South East Asia. The simplest method is based on undrained strength and air voids criteria, as described by Pickens (see IRRD no 250926). Minimum values of shear strength (commonly 100 kPa to 150 kPa) and maximum value of air voids (8% to 12%) are specified. The method is easy to use and control testing involves density and water measurements. At each control point, measurements are also made of shear strength. For the covering abstract see IRRD 820605.
