A PRELIMINARY EVALUATION OF PAVED AND UNPAVED ROAD PERFORMANCE IN BRAZIL

The study of unpaved and paved road performance was a principal part of the "Research of the Interrelationships of Road Construction, Maintenance and User Costs" conducted in Brazil during the period 1975 to 1979. The paper outlines the experimental design methodology and measurement techniques for the pavement and maintenance studies. Preliminary results of the performance of unpaved and paved roads, monitored on 30 unpaved sections and 65 paved sections in Brazil, are discussed. Equations predicting roughness, rut depth and gravel loss, are presented for unpaved roads. These performance parameters are a function of average daily traffic, horizontal alignment, vertical geometry, wearing course material type, maintenance and wet or dry season. Preliminary findings of analyses of roughness and rut depth on paved roads are also discussed. /Authors/
