Research has shown that better compaction of dense coated macadam road bases would markedly improve the structural performance of pavements. Results from compaction trials show that modern vibratory rollers of mass 2 to 14 tonnes are, for a given number of passes, capable of achieving up to about 3 per cent more compaction than present deadweight machines. The characteristics of deadweight and vibratory rollers that influence compaction are considered, so too are the practical aspects of using the vibratory machines. Trial procedures are outlined for testing the effectiveness of rollers and the importance of correct use and proper training of operators is recognised. (Author/TRRL)
