LITERATURE SURVEY ON RATIONAL FLEXIBLE PAVEMENT DESIGN

THE PURPOSE IS TO DEVELOP LABORATORY TESTS FOR DETERMINING THE STRESS-STRAIN RELATIONSHIPS FOR BOTH GRANULAR AND COHESIVE SOILS. IF THE RESPONSE OF SOILS AND OTHER PAVING MATERIALS UNDER VARIOUS LOADING AND ENVIRONMENTAL CONDITIONS COULD BE PREDICTED IN THE LABORATORY, THE USE OF CONTINUUM MECHANICS AND THE FINITE ELEMENT METHOD WOULD MAKE POSSIBLE THE DETERMINATION OF STRESSES AND STRAINS IN A PAVEMENT, SHOULD THE SAME CONDITIONS EXIST IN THE FIELD. THIS WILL FINALLY LEAD TO A RATIONAL METHOD OF PAVEMENT DESIGN BY WHICH THE THICKNESS OF PAVEMENTS CAN BE DETERMINED, SUCH THAT THE STRESSES AND STRAINS IN THE PAVEMENT AND SUBGRADE WILL NOT EXCEED PERMISSIBLE VALUES. THIS RATIONAL METHOD HAS LONG BEEN USED FOR THE DESIGN OF STRUCTURES. HOWEVER, DUE TO THE LACK OF RELIABLE CONSTITUTIVE RELATIONS FOR SOILS AND OTHER PAVING MATERIALS AND THE LARGE NUMBER OF FACTORS AFFECTING PAVEMENT PERFORMANCE, A RATIONAL METHOD OF GENERAL APPLICABILITY HAS NOT BEEN DEVELOPED FOR PAVEMENTS. TO INSURE THAT THE CONSTITUTIVE RELATIONS DEVELOPED ARE ADEQUATE, A SURVEY OF LITERATURE CONCERNING THE THEORETICAL METHODS OF PAVEMENT DESIGN CURRENTLY BEING USED IS NEEDED. AS A FRAMEWORK FOR SUCH A SURVEY, QUESTIONS RELATED TO RATIONAL PAVEMENT DESIGN WERE RAISED BY B. O. HARDIN, WHICH WERE THEN ANSWERED BY Y.H. HUANG BASED ON A REVIEW OF LITERATURE. THESE QUESTIONS AND ANSWERS ARE PRESENTED.
