Summary

This paper investigates the mechanical properties of the concretionary laterites from the rain forest and the savannah zones of Nigeria. It then compares these properties to those of crushed granitic gravel and hardened ferruginous laterite conglomerate. The results show that these concretionary laterites have superior properties to the crushed granitic gravel used in this investigation. The hardened ferruginous laterite conglomerate had the worst properties for road construction. The excellent properties of these concretionary laterites are used to explain the longevity of the earlier roads constructed in Ondo State of Nigeria for light to medium dense traffic.

Les proprietes mecaniques des laterites concretionnees des zones de forets pluvieuses et des Savanes du Nigeria

Résumé

Dans cet article, on étudie les propriétés mécaniques des latérites concrétionnées des zones de forêts et de savanes du Nigéria. On les compare à celles de granulats broyés granitiques et de conglomérats latéritiques ferrugineux indurés. Les résultats montrent que ces latérites concrétionnées ont des propriétés supérieures à celles des premiers. Quant aux seconds, ils ont les moins bonnes propriétés vis-à-vis d'une utilisation routière. Les excellent propriétés des latérites concrétionnées expliquent la longévité de la plus ancienne route construite dans l'état d'Ondo au Nigéria pour un trafic léger à moyennement dense.
