BITUMINOUS RESURFACINGS ON FLEXIBLE PAVEMENTS

The report summarizes data collected over a 6-year period on 29 bituminous resurfacings on flexible pavement. Twenty-one were measured before the resurfacing was applied and all were measured periodically between 1969 and 1974. The measurements consisted of those necessary to compute serviceability indices, as well as Benkelman beam rebound deflections. The results showed that the standard 1- and 2 1/2-in. overlays used in New York State are sufficient to extend the serviceable life of a flexible pavement from a minimum of 6 to about 12 years. Several factors must be taken into account, however, when determining which roads should be overlaid and what thickness to use, including deflection magnitude, condition of the original pavement, and total asphalt thickness in relation to anticipated traffic loadings. A procedure using these factors is discussed, along with reasons for not depending solely on deflections in establishing necessary overlay thicknesses. The data, as a whole, indicate that New York's current practice for resurfacing flexible pavements is generally a good investment of maintenance money, providing an adequate service life for a reasonable period.
