IDENTIFICATION OF PROBLEM LATERITE SOILS IN HIGHWAY ENGINEERING: A REVIEW

Some laterite materials are known to be either inferior pavement aggregates or troublesome highway and earth dam construction materials. However, not all laterite soils belong to this group. A criterion for distinguishing problem laterite soils from non-problem ones for highway construction is proposed. Such a differentiation would be a considerable asset to highway engineers in determining the quality and suitablility of doubtful laterite soils for highway and airfield construction. Laterite soils range in performance from excellent to poor, and in spite of considerable field and laboratory studies on these soils it is still not yet possible to predict accurately the behavior of all grades and genetic groups of laterite soils. From an engineering viewpoint, a criterion based on significant engineering characteristics, including such genetically inherent properties as sensitivity to drying and remolding, degree of potential swell and self-stabilization, and predominant clay minerals, may be more useful in predicting probable in situ behavior of laterite soils than the existing temperate-zone soil classification systems.
