INFLUENCE OF GEOLOGY AND PHYSICAL PROPERTIES ON STRENGTH CHARACTERISTICS OF LATERITIC GRAVELS FOR ROAD PAVEMENTS

LATERITIC GRAVELS ARE THE COMMONLY AVAILABLE LOCAL MATERIAL FOR ROAD AND AIRFIELD CONSTRUCTION IN THE TROPICS AND SUBTROPICS. BECAUSE OF THE WIDE VARIATIONS IN THEIR NATURE AND PHYSICAL PROPERTIES, THE SELECTION OF AN APPROPRIATE TYPE OF LATERITIC GRAVEL PRESENTS SOME PROBLEMS. IN THE PRESENT STUDY THE EFFECT OF GEOLOGY, CLIMATE, AND TOPOGRAPHY ON THE NATURE AND FORMATION OF SUCH GRAVELS IS STUDIED. AS A RESULT OF THE INVESTIGATIONS, THE LATERITIC GRAVELS ARE DIVIDED INTO 4 GROUPS ON THE BASIS OF GEOLOGY AND PHYSICAL PROPERTIES. THE STUDY INDICATES THAT THE PROPOSED GROUPS HAVE A DISTINCT RANGE OF ENGINEERING PROPERTIES THAT CAN BE DEPICTED FROM SIMPLE PHYSICAL PROPERTIES. THE RESULTS OBTAINED HAVE BEEN APPLIED TO ROAD FAILURE STUDIES IN GHANA, AND OBSERVATIONS ON THE PERFORMANCE OF EACH GROUP OF SAMPLES ARE MADE. THE STUDY IS CONSIDERED USEFUL FOR MAKING A JUDICIOUS CHOICE OF LATERITIC GRAVELS FOR SATISFACTORY PERFORMANCE AND ADEQUATE STABILITY OF ROAD PAVEMENTS. /AUTHOR/
