CLASSIFICATION AND ENGINEERING PROPERTIES OF LATERITIC MATERIALS

THE RESULTS OF A 2-YEAR STUDY OF LATERITES AND LATERITIC SOILS IN SOUTHEAST ASIA ARE PRESENTED. INCLUDED IS AN ENGINEERING DEFINITION OF VARIOUS TYPES OF LATERITIC MATERIALS TOGETHER WITH A RECOMMENDED CLASSIFICATION SYSTEM THAT IS AN EXTENSION OF THE UNIFIED CLASSIFICATION SYSTEM. APPROPRIATE SYMBOLS REPRESENTING THE DURABILITY CHARACTERISTICS OF LATERITIC GRAVELS AND SANDS AND THE DEGREE OF PLASTICITY OF THEIR FINES ARE INCLUDED WITH SUGGESTED TEST PROCEDURES. A PAVEMENT EVALUATION STUDY WAS CONDUCTED ON 101 TEST SECTIONS ON THE THAILAND ROAD SYSTEM. THE EXPERIMENT DESIGN INCLUDED THE VARIABLES OF SUBGRADE STRENGTH, RAINFALL, DRAINAGE, AND TRAFFIC LOADING. BASE AND SUBBASE COURSES OF BOTH LATERITIC AND NONLATERITIC MATERIALS WERE INCLUDED IN THE STUDY. FIELD AND LABORATORY TESTS WERE PROGRAMMED OT OBTAIN DATA FOR RELATING ENGINEERING PROPERTIES OF LATERITIC MATERIALS TO OBSERVED PERFORMANCE. AN EQUATION RELATING ENGINEERING PROPERTIES OF MATERIALS TO PAVEMENT GEOMETRY IS PRESENTED. /AUTHOR/
