Abstract: This appendix discusses the methods used to classify soils for the preliminary Thailand study and presents pedological soil profile descriptions. One major purpose of a soil classification system is to provide a basis whereby a classifier can convey to others the pertinent soil characteristics of an area within a common reference framework. The capability of estimating soil strength from values of such discrete properties as texture, moisture content, plasticity, organic-matter content, and density is materially improved by categorizing soils in terms of two of the several existing systems of soil classification: (a) the Unified Soil Classification System (uses), and (b) the pedological system employed by the U. S. Department of Agriculture (USDA) and by the current soil survey program in Thailand. These two systems were employed in this study and are briefly discussed in the following paragraphs. A third method, the Soil Trafficability Classification (STC) scheme, was not used because sufficient wet-season soil strength data were not available to reduce USCS soil types to discrete STC groups.
