Abstract

In Turkey, the use of RCC pavements is increasing in urban and rural roads. However, a detailed study examining the effect of RCC mixture parameters on the pavement surface properties that affect road driving comfort and safety is not available in literature. In this study, in order to cover that gap in literature 12 RCC mixtures prepared with different cement dosages, aggregate gradations and water amounts were compacted by "Superpave-Gyratory-Compactor" at different levels. Later, the surface characteristics were evaluated with British pendulum and sand patch tests. It was concluded that cement dosage, water content and gradation have an effect not only in terms of strength but also in terms of pavement surface properties, and recommendations were made for RCC mixture optimization.
