An Engineering Soil Survey of Fayette County, Kentucky

Abstract

AGRICULTURAL SOIL SCIENTISTS HAVE DEVELOPED A SYSTEM OF SOIL CLASSIFICATION AND MAPPING THAT HAS BEEN AND IS CONTINUING TO BE OF GREAT VALUE TO THE SOILS ENGINEER IN RECONNAISSANCE AND MAPPING. THIS REPORT COVERS A STATISTICAL METHOD OF CORRELATION USED IN A PILOT STUDY CONDUCTED IN ORDER TO MAKE ENGINEERING SOILS DATA AVAILABLE FROM A PEDOLOGICAL MAP OF FAYETTE COUNTY, KY. ASSUMING THAT THE RELIABILITY OF PEDOLOGICAL CLASSIFICATIONS HOLDS TRUE FOR ENGINEERING PROPERTIES, THE ENGINEERING TEST CONSTANTS FOR A GIVEN HORIZON OF A GIVEN SOIL SHOULD FALL WITHIN A NARROW RANGE, AND THE LIMITS OF THIS RANGE SHOULD BE REASONABLY DETERMINABLE FROM THE RESULTS OF TESTS ON A SMALL NUMBER OF RANDOM SAMPLES. IN THE PRESENT STUDY A RANGE WITH A CONFIDENCE COEFFICIENT OF 0.90 WAS DETERMINED BY THE STATISTICAL METHOD USED. /AUTHOR/
