Framework for Selecting Effective Preventive Maintenance Treatments for Flexible Pavements

摘要: Preventive maintenance techniques are considered useful in extending the life of a pavement if applied at right time. Discussed here is framework for process that can be used to select proper strategies different distress types asphalt pavements, depending on traffic level and environment. Maintenance treatments addressed include only crack seals, fog slurry microsurfacings, chip thin concrete overlays, other surface treatments. Types roughness, rutting, fatigue cracking, longitudinal raveling, weathering, bleeding. Decision trees, based authors' experiences, presented illustrate selecting appropriate A evaluating cost-effectiveness various presented. Existing methods discussed together with their strengths weaknesses. An example also briefly
