FACTORS CONTROLING PROPERTIES AND DURABILITY OF CONCRETIONARY LATERITE GRAVEL AGGREGATES

The results are presented of a study to determine the most important factors that influence the quality of concretionary latrite gravel aggregates. The study involved the use of factor analysis (R-mode) in assessing the significance and relative importance of the various aggregate tests on the quality of concretionary laterite gravels. the study assessed the influence of parent material type on the identified factors by cluster analysis. It was found that the degree of laterization measured in terms of ratios of silica to iron oxides, dominates (up to 51%) the engineering behavior of concretionary laterite gravels. The other important factor groups represent the various aspects of the void characteristics and are of secondary importance. The relative importance of the various factor groups and their associated aggregate properties are influenced by the parent material rock types.
