Use of pavement evaluation techniques in maintenance management by the New York State Thruway Authority.

Pavement evaluation reports are used as a management tool on the New York Thruway. Projections covering long-range maintenance are updated annually by running a roughometer survey over the entire Thruway. Service life curves are adjusted if necessary by the following factors: (1) Yearly traffic volumes which are automatically tabulated from toll records, (2) Comparison of the roughometer surveys, (3) Establishment of new pavements serviceability on new values and overlays, and (4) Occasionally crack and patch surveys are conducted in local areas.
