ABSTRACT:
For the formation of a substantially crack-free paved surface, pressure is applied to a layer of asphalt substantially simultaneously by means of longitudinally-spaced-apart, rollingly-movable pressure areas and by means of substantially continuously applied pressure to substantially the entire bottom inner area of a flat, endless, elastomeric belt extending between the two longitudinally-spaced-apart, rollingly-movable areas, whereby the continuously applied pressure is transferred to substantially the entire bottom outer area of the endless elastomeric belt which extends between the two longitudinally-spaced-apart, rollingly-movable areas.
