THE USE OF ROLLERS IN THE CONSTRUCTION OF BLACK-TOP PAVEMENTS
WALZENEINSATZ BEIM SCHWARZDECKENBAU
The development of black-top pavement structures shows a trend towards one-layer base courses 15-18 cm thick. The advantage is that it saves time; the disadvantage is that greater compaction efforts are required. Attempts are made at replacing the use of three different types of rollers by one heavy vibrating roller. A new feature is the infinitely variable forward and backward control of rollers to avoid wave formation in the surfacing. The front and rear wheel drive performs well. Thicker base courses require heavier rollers. Rubber-tyred rollers are used on road bases and surface layers (service load of up to 28 metric tons) and in particular if the hot and dry method is applied. A number of commercial machines are described. /TRRL/
