EXPERIMENTAL MODELS FOR THE PERFORMANCE OF ASPHALT CONCRETE OVERLAYS. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

The Road Research Institute of the National Highway Department of Brazil (IPR/DNER) has inventoried data about the performance of several experimental sections located in various roads. Fifteen sections among them were overlayed with asphalt concrete and have been systematically monitored since 1977. The available data refer to roughness, cracking, rut depths and Benkelman beam deflection and have been employed for the development of performance prediction models for overlayed pavements. This paper presents the latest developed models, presently used by DNER in the design of overlays. These models may be used also as tools for the optimization of investments in pavement management systems.
