Developments in compaction practise are discussed and in particular the increasing demand for large self-propelled, pneumatic tyred, rollers. The growing acceptance of the advantages of pneumatic tyred rollers has followed the number of premature pavement failures since the advent of large vibratory rollers. It is now realised that it is practically impossible to prevent de-densification due to over-compaction of medium-to-low pi soils, or stabilised material, when vibratory rollers are exclusively employed. The difficulties of obtaining exact compaction control by vibratory roller can be overcome with self-propelled pneumatic tyred rollers which have shown greater effectiveness and improved rolling speeds of 200-300%. The advantages of pneumatic tyred compactors are discussed in detail. (TRRL)
