ABSTRACT:
Apparatus is described for obtaining uniform compaction of asphalt concrete to reduce or prevent cracking of the asphalt concrete surface. A mobile confinement edge force is maintained in contact with the edge surface of an asphalt concrete mat while the mat is being compacted. This is performed in a manner such that the density of the mat across the full width of the mat becomes uniform. By obtaining uniform density of each lane of the mat as it is laid significantly reduces the incidence of joint cracking and deterioration of the asphalt concrete, in the longitudinal joint area, over time.
