Method of asphalt paving and pavement

A process for paving a sub-base surface with compactable asphaltic concrete comprising aggregates forming aggregate interlocks, and an asphaltic cement to provide a finished longitudinally extending asphaltic pavement having dormant zones of potential fracture at predetermined longitudinally spaced locations, the process 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 opposite, longitudinally extending edges and comprising asphaltic cement and larger and smaller aggregate size fractions;
• b) displacing said asphaltic cement and said aggregates to create a plurality of temporary open score lines in said mat before compacting and to interrupt all of said aggregate interlocks along said score lines in at least the top one third of said mat thickness at said predetermined longitudinally spaced locations, said open score lines being transverse to said longitudinal direction at said longitudinally spaced locations, and said score lines extending generally in a direction from one of said longitudinally extending edges to the other of said longitudinally extending edges;
• and
• c) compacting said mat of compactable asphaltic concrete to reestablish said aggregate interlocks between said smaller aggregate size fractions and to close and seal said open score lines and 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 longitudinally spaced locations.

• b) displacing said asphaltic cement and said aggregates in said mat by a scoring tool before compacting to create a plurality of temporary open score lines having opposed facing sidewalls and being transverse to said longitudinal direction at longitudinally spaced intervals, said open score lines extending in a direction from one of said longitudinally extending edges to the other of said opposite longitudinally extending edges;
• and
• c) compacting said mat of compactable asphaltic concrete to close and seal said open score lines and bond said facing sidewalls together 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 that are substantially concealed at said longitudinally spaced intervals and that are impervious to liquid unless fractured, said dormant zones of potential fracture extending generally transverse to said longitudinal direction in a direction from one of said longitudinally extending edges to the other of said longitudinally extending edges.
