THEORY OF COMPACTION USING VIBRATORY ROLLERS AND SOME RELEVANT PRACTICAL CONSEQUENCES

DIE THEORIE DER VIBRATIONSWALZVERDICHTUNG UND EINIGE PRAKTISCHE KONSEQUENZEN DARAUS

The properties of different rollers are compared to a so-called roller-characteristic which is defined as the specific pressure of the wheels on the asphalt surface. The value of the roller-characteristic cw is calculated in the case of non-vibrating rollers from the weight p and the wheel width I and the wheel diameter D using the formulae cw=p/(id). For pneumatic tyred and vibratory rollers equivalent values must be ascertained by means of appropriate tests. Recommendations are presented for the more favourable utilization of the various types of rollers. Summarizing the experience it is stated that pneumatic tyred rollers are best used for the first passes in the "hot and dry" process; with thick bituminous layers this roller has a very high compaction capacity and the best compaction results. With thinner layers, more difficult to compact, the vibratory roller has distinct advantages. /TRRL/
