PAVEMENT DESIGN CONCEPT FOR TROPICAL COUNTRIES /IN FRENCH/

THE ARTICLE STRESSES THE DIFFERENCES BETWEEN TROPICAL AND TEMPERATE ENVIRONMENTAL FACTORS AND THEIR INFLUENCE ON ROAD CONSTRUCTION AND MAINTENANCE. THE THREE MAIN PHASES OF TROPICAL PAVEMENT DESIGN ARE REVIEWED: (1) FROM 1950 TO 1955, TWO MAIN TECHNIQUES WERE USED: MACADAM AND BITUMEN-STABILIZED SOIL. THE PERFORMANCE OF BOTH MATERIALS PROVED SATISFACTORY; (2) FROM 1955 TO 1964, LOCAL MATERIALS, ESPECIALLY LATERITIC GRAVEL, WERE UTILIZED; (3) THE PRESENT PHASE IS CHARACTERIZED BY AN INCREASE IN TRAFFIC AND THE USE OF MORE COSTLY TECHNIQUES: GRAVEL STABILIZED WITH CEMENT, CRUSHER MATERIAL, AND GRAVEL-BITUMEN. NEW TRENDS ARE DEFINED AND ATTENTION IS DRAWN TO THE NEED FOR FURTHER RESEARCH INTO THE DEVELOPMENT OF NEW TEST METHODS TO SIMULATE REAL TRAFFIC CONDITIONS, THE ADOPTION OF NEW QUALITY CRITERIA FOR SECONDARY ROADS, MORE DETAILED TRAFFIC STUDIES, AND SURVEILLANCE AND MAINTENANCE OF CARRIAGEWAYS. /TRRL/
