Engineering soils and geologic maps are proving to be invaluable tools of engineers, industrial leaders, community planners, and administrators during tbe preliminary stages of planning and site selection for major construction projects and the development of plans to use nature's basic resource--the land. Quantitative engineering data for soils and geological formations, and the interpretation of tbese data, are important factors to consider in the best land-use plans and in providing stable foundations and proper usage of earth materials for highways, buildings, and other earth structures. Engineering soils and geologic maps can be used to great advantage by planners and engineers to 1) make soil and geological reconnaissance surveys, 2) organize and check field surveys, 3) correlate and predict performances of soil and geological materials, and 4) locate construction material and resource deposits.
Recognizing the need and demand for this type of information, the Research Division of the Kentucky Department of Highways has undertaken a pilot study to report tbe engineering geognosy of a selected area in Kentucky. The area reported herein is located in the vicinity of Ashland.
This report discusses the engineering properties and behavior of unconsolidated surficial deposits and consolidated bedrock materials in Boyd County, Kentucky. It is based mainly on an interpretation of engineering test data retrieved and summarized from Kentucky Department of Highways' design and construction plans for routes I 64, KY 3, and US 60, which pass tbrough the area; a soils report (1) prepared by the Soil Conservation Service for the city of Ashland; and published geologic reports and maps (2, 4, 5). Engineering soils and geologic maps and interpretations presented in this report should be viewed from a standpoint of rapidly providing generalized engineering information of the different soil and rock materials in the subject area. For important earthwork and foundation engineering purposes and for detailed and specific data, it is recommended that the soil and rock materials at a particular site be explored and tested thoroughly.
