A STUDY OF THE RELATIONSHIP BETWEEN COMPACTION, MIX COMPOSITION, AND PERFORMANCE OF DENSE BITUMEN MACADAM WEARING COURSES IN NORTHERN IRELAND --COMPACTION TECHNOLOGY. PROCEEDINGS OF THE CONFERENCE ORGANISED BY NEW CIVIL ENGINEER, LONDON, OCTOBER 29, 1987

The paper considers the main factors that affect the performance of dense bitumen macadam (dbm) wearing courses in northern Ireland. The influence of compaction was assessed after the percentage refusal density (prd) test was shown to be a suitable method of assessing the level of compaction of this material. During the course of the research the importance of mix composition was also identified. A series of site investigations in conjunction with an extensive laboratory testing programme enabled the authors to examine the effect of variations in compaction level and mix composition on performance. A minimum level of compaction, in terms of prd, was recommended for dbm wearing courses in northern ireland.(a) for the covering abstract of the conference see IRRD 812720.
