Book Description
The performance of in-service typical Virginia flexible and rigid pavements in all areas of the state is under evaluation. The objectives are to provide a ready reference for designers and field engineers and to provide background information for design improvement. Periodic deflection and roughness tests are conducted along with field inspections. The records maintained on each pavement reflect condition, traffic, construction costs, and major repairs. Among the major findings of the study to date are: (1) Cement stabilized subgrades under recently constructed flexible pavements have virtually eliminated rutting and other major distortions, (2) The cumulative number of trailer trucks and buses sustained by a pavement up to a fixed degree of cracking is directly related to a parameter used to define the shape of the Dynaflect deflection basin, and (3) Terminal PSI as defined from the AASHO Road Test is too insensitive for use in the evaluation of flexible pavement performance in Virginia.

Book Description
Extensive studies of over 800 miles of divided interstate pavements constructed prior to July 1, 1975, are reported. The studies included those of performance adequacy and the identification of certain factors which appeared to adversely affect performance. The studies showed that Virginia interstate pavements have performed very well in spite of some serious problems for which the causes have been identified and corrected in current standards and specifications. Six instances where location, pavement age, and traffic permitted valid comparisons between portland cement and bituminous concrete pavements showed the two pavement types to be performing similarly and to have incurred very similar maintenance costs. Ten recommendations relating to design, construction, and maintenance are presented. A major recommendation encourages the Department to continue to consider all the existing pavement types with appropriate modifications, for use on future construction. No major design modifications are recommended.

Book Description
The construction and performance of seven Virginia flexible pavements containing at least some experimental features were evaluated. The objective was to evaluate the performance of the pavements incorporating new or timely design concepts and to assess the flexibility of these concepts for further use.
