COMPACTION CONTROL OF COHESIVE FILL

This paper reviews compaction control of cohesive fill soils with emphasis on problems caused by variable soils, and on improved methods of control testing. Compaction control is discussed in relation to soil properties, design requirements, specifications, field methods, costs and practical limitations. It is concluded that: (1) most existing control is inadequate; (2) most specified standards of compaction bear little relationship to design requirements; (3) the most commonly used control test procedures are too slow and costly; (4) thorough soil , testing is necessary before meaningful compaction standards can be assessed; (5) simpler, faster and more reliable control test methods are feasible if appropriate undertaken for the National Roads Board on base course and compaction standards should be applied where adequate control is not feasible or cannot be afforded. It is recommended that: (1) thorough pre-design studies be undertaken in all cases; (2) specifications should be rewritten in new terms which set realistic standards; (3) the use of air voids and index tests as control test criteria be pursued; (4) post construction performances be evaluated; and (5) the contractor do most of the control testing. /AUTHOR/
