KEYNOTE ADDRESS, EFFECTS OF TEMPERATURE AND HEAT ON ENGINEERING BEHAVIOR OF SOILS

BACKGROUND IS PRESENTED ON THE THEME OF THE SYMPOSIUM EFFECTS OF TEMPERATURE AND HEAT ON ENGINEERING BEHAVIOR OF SOILS, CALLED BY MEMBERS OF THE COMMITTEE ON PHYSICO- CHEMICAL PHENOMENA IN SOILS. KNOWLEDGE OF SOIL THERMAL PROPERTIES IS OF PRIMARY IMPORTANCE IN UNDERSTANDING THE CHARACTERISTIC SOIL PROFILE, WATER ACCUMULATION, FROST HEAVE, STABILITY LOSS, CORROSION, AND OTHER PROBLEMS THAT MUST BE SOLVED BY THE HIGHWAY ENGINEER. THE TOPICS THAT FALL WITHIN THE SCOPE OF THE SYMPOSIUM ARE: (1) THE PHYSICAL NATURE IF THERMAL ENERGY, CAPACITY AND INTENSITY FACTORS, THERMODYNAMICS, ACTIVATION ENERGY AND REACTION RATES, (2) THERMAL CHARACTERISTICS OF THE MAIN SOLID COMPONENTS OF SOILS, (3) THE EFFECT OF TEMPERATURE ON THE INTERACTION OF SOIL COMPONENTS INCLUDING LESSONS FROM CERAMICS, (4) THERMALLY INDUCED MOISTURE FLOW IN SOILS AND ACCOMPANYING ELECTRIC PHENOMENA, (5) THE INFLUENCE OF TEMPERATURE ON CONSISTENCY, STRENGTH, AND COMPRESSIBILITY OF SOILS, (6) EFFECT OF TEMPERATURE ON HARDENING AND CURING RATES OF SOIL- CEMENT, SOIL LIME, AND OTHER STABILIZED SOIL SYSTEMS, (7) THERMAL STABILIZATION DYNAMIC TOOLS OF QUALITATIVE OR SEMI- QUANTITATIVE CHARACTER ARE DISCUSSED. QUALITATIVE USE OF THERMODYNAMICS CAN INDICATE THE DIRECTION IN WHICH A SOIL SYSTEM CHANGES UNDER KNOWN OR EXPECTED ENVIRONMENTAL INFLUENCES AND CAN POINT OUT THE TYPE OF TESTING OR EXPERIMENTATION THAT SHOULD BE DONE ON THE SYSTEM TO OBTAIN MEANINGFUL INFORMATION. THE RAPIDLY DEVELOPING DISCIPLINE OF THERMODYNAMICS OF GRANULAR SYSTEMS IS AN IMPORTANT APPLICATION.
