ABSTRACT:
A process for paving a surface of a sub-base with compactable asphaltic concrete comprising aggregates and an asphaltic cement to provide a finished asphaltic pavement having dormant zones of potential fracture at predetermined locations. The process comprises the steps of forming a continuous mat of compactable asphaltic paving concrete having a predetermined thickness on the surface of a sub-base; creating dormant zones of potential fracture at predetermined locations in the mat prior to compacting the compactable asphaltic paving concrete; and compacting the mat of compactable asphalt concrete to seal the dormant zones and provide a finished asphaltic pavement of predetermined density having a smooth traffic bearing top surface with the sealed dormant zones of potential fracture substantially concealed therein.
