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.

[ What is claimed is:] [1.] A process for paving a sub-base surface with compactable asphaltic concrete including aggregates and an asphaltic cement to provide a finished asphaltic pavement having dormant zones of potential fracture at predetermined locations, the process for paving comprising the steps of:a) forming on said sub-base surface a continuous longitudinally extending mat of compactable asphaltic paving concrete of predetermined thickness, the mat having a longitudinal direction and including asphaltic cement and aggregates;b) displacing said asphaltic cement and said aggregates in said mat before compacting to create a plurality of spaced apart temporary open score lines extending generally parallel to said longitudinal direction; andc) compacting said mat of compactable asphaltic concrete to close and seal said open score lines and to provide a finished asphaltic pavement of predetermined density having a smooth uninterrupted traffic bearing top surface wherein said closed sealed score lines define a plurality of dormant zones of potential fracture substantially concealed at said spaced intervals, said dormant zones of potential fracture extending generally parallel to said longitudinal direction of said mat.
