The author states that vibratory compaction of engineering materials began in earnest less than 50 years ago, and the development of vibratory compaction leading up to present day techniques is discussed. It is suggested that the design principles that have emerged are being applied in designing and building rollers specifically for use on asphalt-aggregate mixtures. But to use vibratory rollers properly, the author considers that the basic factors which influence vibratory compaction and how the compactor relates to them, must be understood by all concerned, including the roller operator. Vibratory rollers are described as being made with one or two smooth surfaced steel-tyred drums 0.75 to 1.5 M diameter and 0.9 to 2.7 M width. The vibrations are generated by eccentric weights on independent rotating shafts, the rotational speed of which determines the frequency. The rollers vary in mass from 1.4 to 15.5 tonnes, and steel-tyred tandem vibratory rollers from 6 to 15.5 tonne mass are recommended for street, highway and airport pavements. The factors which influence vibratory compaction are discussed, and by reference to a series of diagrams information is provided on mass, centrifugal force, frequency, roller speed and mix properties. Operating methods are also described, and joint rolling procedure discussed in relation to both static rollers and vibratory rollers. /TRRL/
