FIELD IDENTIFICATION OF SOILS AND AGGREGATES FOR COUNTY ROADS

THE PRIMARY PURPOSE IS TO PROVIDE INSTRUCTION TO INDIANA COUNTY ROAD PERSONNEL ON RATING THE QUALITY OF SOILS AND PIT-RUN MATERIALS USED IN THE CONSTRUCTION AND MAINTENANCE OF COUNTY ROADS. A SYSTEM OF SOIL CLASSIFICATION IS PRESENTED WITH A COMMON LAUGUAGE FOR IDENTIFYING SOIL TYPES PROPERTIES AND PROBLEMS. CHAPTER II, SOIL COMPONENTS, PROPERTIES AND IDENTIFICATION TESTS, PROVIDES INSTRUCTIONS ON THE IDENTIFICATION OF SOIL COMPONENTS, BASED ON THEIR PHYSICAL PROPERTIES AS DETERMINED BY VISUAL EXAMINATION AND SIMPLE HAND TESTS. FIVE SOIL COMPONENTS ARE DEFINED, ALONG WITH THEIR SIZE RANGES, PROPERTIES AND SIMPLE HAND TESTS FOR IDENTIFICATION. THE UNIFIED SOIL CLASSIFICATION SYSTEM IS PRESENTED IN CHAPTER III: THE CLASSIFICATION RECOGNIZES 15 BASIC SOIL GROUPS, HOWEVER, ONLY SEVEN OR EIGHT OF THESE COMMONLY OCCUR HERE IN INDIANA. DEFINITIONS, WORD DESCRIPTIONS AND CLASSIFICATION SYMBOLS ARE SUMMARIZED IN TABULAR FORM. CHAPTER IV, FIELD IDENTIFICATION PROCEDURE, OUTLINES INSTRUCTIONS AND PROCEDURES FOR IDENTIFYING EACH OF THE 15 SOIL GROUPS, USING VISUAL EXAMINATION AND SIMPLE HAND TESTS. THE SOIL IDENTIFICATION PROCESS IS SUMMARIZED IN TABULAR FORM. CHAPTER V, FIELD TESTS FOR AGGREGATE MATERIALS, OUTLINES ADDITIONAL FIELD IDENTIFICATION TESTS. THESE "INDICATOR" TESTS ARE MAINLY FOR PIT-RUN GRAVELS AND SANDS BUT CAN SERVE FOR BOTH IDENTIFICATION AND GENERAL QUALITY EVALUATION TESTS. GUIDE GRADINGS ARE PRESENTED FOR GRAVEL BASE AND SURFACING AGGREGATES. TESTS TO INDICATE THE RELATIVE AMOUNT OF FINES AND RELATIVE PLASTICITY OF FINES ARE ALSO OUTLINED. CHAPTER VI, RATING SOILS AND AGGREGATES AS ROAD MATERIALS, THE 15 SOIL GROUPS ARE RATED WITH RESPECT TO THEIR INHERENT PROPERTIERS AS ROAD-BUILDING MATERIALS. EACH SOIL GROUP IS RATED FOR ITS: (1) LOAD-CARRYING PROPERTIES AS ROAD-BUILDING MATERIALS. EACH SOIL GROUP IS RATED FOR ITS: (1) LOAD-CARRYING PROPERTIES, (2) DRAINAGE PROPERTIES, (3) FROST PROPERTIES, AND (4) COMPACTION PROPERTIES. /AUTHOR/
