SOIL SURVEY PRACTICES IN INDIANA

INDIANA HAS A VARIETY OF GEOLOGICAL FORMATIONS WHICH INFLUENCE HIGHWAY DESIGN AND CONSTRUCTION. THE MAJOR PORTION OF THE SURFACE SOILS ARE THOSE DEVELOPED FROM ILLINOIAN AND WISCONSIN GLACIAL DEPOSITS AND THE RESIDUAL SOILS OF NON- GLACIATED AREAS. LESSER AREAS OF OTHER FORMATIONS ARE ENCOUNTERED. BEDROCK IS ALSO ENCOUNTERED, PRIMARILY IN THE NON-GLACIATED AREAS. EACH OF THESE AREAS PRESENT CERTAIN PROBLEMS WHICH REQUIRE INVESTIGATION. THIS PAPER DISCUSSES THE MAJOR SOILS PROBLEMS WHICH ARE ENCOUNTERED IN HIGHWAY DESIGN AND CONSTRUCTION IN INDIANA. SOIL SURVEYS ARE DIRECTED AT DETERMINING THE PROBLEM AREAS, DETERMINING THE SOILS CONDITIONS, AND MAKING RECOMMENDATIONS AS TO HOW THESE PROBLEMS MAY BE OVERCOME. PROCEDURE FOLLOWED IN MAKING SOIL SURVEYS IS EXPLAINED, INCLUDING PRELIMINARY PLANNING, LOCATION, FREQUENCY, AND DEPTH OF BORINGS; AND THE SOILS REPORT. ILLUSTRATED CASE STUDIES ARE PRESENTED OF A SIDE- HILL CUT AND FILL IN AN ORDOVICIAN FORMATION, A TRI-LEVEL SEPARATION STRUCTURE IN WHICH SATURATED SILTS WERE ENCOUNTERED, A HIGHWAY CUT IN LOESS, AND A 170-FOOT ROCK CUT. /AUTHOR/
