STATISTICALLY CONTROLLED ENGINEERING SOIL SURVEY

SOIL BORINGS MADE AT REGULAR INTERVALS ALONG THE PROPOSED LINE OF RIGHT-OF-WAY FOR A TRANSPORTATION ROUTE DO NOT PRODUCE THE MOST SATISFACTORY ENGINEERING SOIL SURVEY BECAUSE VARIATIONS IN THE PROPERTIES OF NATURAL SOIL UNITS ARE NOT CONSIDERED. AN APPROACH IS PROPOSED FOR THE CONDUCT OF A DETAILED SOIL SURVEY BASED ON THE USE OF SIMPLE STATISTICS. THE SUGGESTED METHOD DISTRIBUTES THE NUMBER OF BORINGS IN ACCORDANCE WITH THE SIZE OF AREA ALONG THE PROPOSED ALIGNMENT OCCUPIED BY EACH TYPE OF SURFICIAL SOIL AND WITH ITS RELATIVE VARIABILITY IN ENGINEERING PROPERTIES. A SURVEY BASED ON THE PROPOSED METHOD SHOULD AVOID PROBLEMS RESULTING FROM A REGULAR PATTERN OF SOIL BORINGS, INCLUDING' /A/ THE POSSIBILITY OF MISSING A DETRIMENTAL SOIL TYPE, /B/ THE CHANCE OF PLACING A VERY SMALL NUMBER OF BORINGS IN AN EXTREMELY ERRATIC SOIL TYPE, AND /C/ THE SAMPLING OF A UNIFORM SOIL TYPE MANY TIMES MORE THAN NECESSARY. /AUTHOR/
