ENGINEERING PEDOLOGY IS DEFINED AS THE SCIENCE OF INVESTIGATING SOIL ENGINEERING PROBLEMS, MAKING USE OF ALL NATURAL LAWS KNOWN TO BE OPERATIVE UNDER THE PARTICULAR AND SPECIFIC CONDITIONS PREVAILING. THE REALIZATION IS PRESENTED THAT THE DYNAMIC FACTORS THAT FORMED A SOIL AND GAVE IT ITS PEDOLOGICAL CHARACTERISTICS CONTINUE TO ACT, THOUGH IN A MODIFIED FORM, IN THE SOIL-SUBGRADE-BASE-PAVEMENT SYSTEM AND DETERMINE TO A LARGE EXTENT THE QUALITY AND THE DURABILITY OF THIS SYSTEM. THE PHILOSOPHY OF PEDOLOGICAL ENGINEERING IS APPLIED TO SHALLOW FOUNDATIONS, GRADE SOIL GROUPS, ORGANIC MATTER AND HUMUS, SOIL STRUCTURE, VOLUME CHANGE, STABILITY REQUIREMENTS, SWELLING PRESSURE AND MOISTURE MOVEMENTS AND MAXIMUM MOISTURE CONTENT UNDER A PAVEMENT. STABILIZATION IS DISCUSSED IN THE SENSE OF MAINTAINING A MINIMUM DESIRABLE SHEAR RESISTANCE IN THREE CATEGORIES: (1) STABILIZATION BY COMPACTION, (2) MECHANICAL STABILIZATION NOT SPECIFICALLY PROVIDING FOR MOISTURE STABILIZATION, AND (3) MOISTURE STABILIZATION INVOLVING THE INCORPORATION OF SOME CHEMICAL SUBSTANCE. THE NEW ENGINEERING DISCIPLINE OF ENGINEERING PEDOLOGY IS DESCRIBED AND WHAT THIS DISCIPLINE CAN DO FOR SCIENTIFIC SOIL STABILIZATION IS PRESENTED.
