The development of a procedure to assess highway routine maintenance needs

This is the first interim report covering the first three tasks of the study. This phase included the development of a procedure for the assessment of routine maintenance needs. The proposed procedure is based on unit foremen's evaluation of highway deficiencies. The validity of the proposed approach was tested in different randomly selected maintenance units. The research team objectively measured the distresses on those sections that were subjectively evaluated by the unit foremen. Both subjective and objective data together with estimations of expected work load by unit foremen provided the basis for statistical analyses of the proposed approach. The report includes a plan for implementation of the procedure (a).
