Evaluation of the Factors Affecting the Wear Resistance of Calcined Bauxite Aggregates

The continuous use of load-bearing road surfaces often results in degradation over time, particularly if they are constructed from cement or aggregates that were poorly polished. Surfaces prepared from calcined bauxite exhibit good skid resistance properties, and this work describes a comparison of...
