ABSTRACT OF THE DISCLOSURE A novel asphalt compacting machine of the type having a chassis, a drive roller, e.g. at the rear and a steerable rolling compaction mechanism, e.g., at the front, is provided herein. The improvement resides in the provision of a front, preferably steerable, rolling compaction mechanism which comprise two longitudinally-spaced-apart tandem rigid drums, preferably free-wheeling, which extend across the entire lateral width of the chassis. The drums entrain an elastomeric, e.g. rubber, asphalt-compaction belt therearound. A lower means, e.g. a flat plate, is operatively associated with the rolling compaction mechanism and is disposed between the rigid drums to engage substantially the entire bottom inner surface of the belt between the two rigid drums. In this way, substantially the entire outer bottom surface of the belt between the two rigid drums is urged downwardly into pressure contact with the asphalt being compacted, thereby to provide a flat, pressure-applying surface. Newly laid asphalt paving compacted with such a compaction machine shows substantially no cracks therein.
