NEW CONCEPTS IN BASE COURSE CONSTRUCTION WITH ASPHALTS

THE DEVELOPMENT OF ASPHALT BASES IN TODAY'S MODERN HIGHWAY SYSTEM HAS FOLLOWED A PATTERN SIMILAR TO MOST OTHER ENGINEERING ADVANCES. AS HIGHWAY PERFORMANCE DEMANDS INCREASED, THE COMBINED RESOURCES OF THE VARIOUS HIGHWAY DEPARTMENTS AND INDUSTRY DEVELOPED IMPROVED DESIGN METHODS, CONSTRUCTION PROCEDURES, AND PRODUCTS. THE DEVELOPMENT OF ASPHALT BASES IS REVIEWED FROM THEIR ORIGIN TO THEIR USE IN HEAVY-DUTY HIGHWAY SYSTEMS. THE DEVELOPMENT IS PRESENTED IN LIGHT OF CURRENT EMPIRICAL AND THEORETICAL DESIGN METHODS AS WELL AS NEW CONSTRUCTION PROCEDURES AND ASPHALT PRODUCTS. INCLUDED ARE A CLASSIFICATION SYSTEM FOR ASPHALT BASES, A REVIEW OF FACTORS IMPORTANT TO THE DESIGN OF ASPHALT BASES, THE CONCEPT OF HIGHER ASPHALT CONTENT BASES TO MINIMIZE FLEXURAL FATIGUE FAILURES, THE USE OF 'LAYER EQUIVALENCIES' AS A CONVENIENT BASIS FOR ECONOMICAL DESIGN, AND FACTORS IMPORTANT TO THE QUALITY OF ASPHALT BASES IN ASPHALT MACADAM, ASPHALT CONCRETE, ASPHALT TREATED, AND ASPHALT SOIL BASES.
