COMPACTION OF FLEXIBLE PAVING USING VIBRATING ROLLERS

This article is concerned with the use of vibrating rollers to compact flexible pavings. The author first refers to the controversial nature of the subject and to the different opinions that have been held in America, Britain and the continent. Reference is made to the lightweight tandem rollers introduced in the 1950s and the need for additional rolling by heavier static rollers. Initial development was towards 1 1/2-4 tonne machines incorporating a single vibrating drum and a non-vibrating steering drum. These were designed for base course materials such as lean concrete and were adapted for bituminous materials, and gained popularity in Scandinavia and Germany. Mention is made of the development of 8, 10 and 12 tonne vibrating tandem rollers in America in the 1960s, following experimental models used for motorway construction to the Marshall specification. These incorporated articulated frames and a vibrating drum in each section, some of which allowed variable amplitude and frequency. Reference is made to the interest taken by authorities in the United Kingdom and on the continent and to the thicknesses of compaction possible. The author refers to tests on the seven oaks bypass and elsewhere which established that thicker lifts were rolled more quickly and at lower temperatures than with static rollers. Better compaction at joints and satisfactory bonding between wearing and base course were also reported. The author concludes that vibrating rollers of the right characteristics can be successfully used to compact flexible pavements. /TRRL/
