Stiles Mining Resource-Custom Soil Resource Report for <br /> Asphalt Specialties Co., Inc. <br /> Soil Reports <br /> The Soil Reports section includes various formatted tabular and narrative reports <br /> (tables)containing data for each selected soil map unit and each component of <br /> each unit. No aggregation of data has occurred as is done in reports in the Soil <br /> Properties and Qualities and Suitability and Limitations sections. <br /> The reports contain soil interpretive information as well as basic soil properties and <br /> qualities.A description of each report(table)is included. <br /> Soil Qualities and Features <br /> This folder contains tabular reports that present various soil qualities and features. <br /> The reports (tables) include all selected map units and components for each map <br /> unit. Soil qualities are behavior and performance attributes that are not directly <br /> measured but are inferred from observations of dynamic conditions and from soil <br /> properties. Example soil qualities include natural drainage, and frost action. Soil <br /> features are attributes that are not directly part of the soil. Example soil features <br /> include slope and depth to restrictive layer. These features can greatly impact the <br /> use and management of the soil. <br /> Soil Features <br /> This table gives estimates of various soil features. The estimates are used in land <br /> use planning that involves engineering considerations. <br /> A restrictive layer is a nearly continuous layer that has one or more physical, <br /> chemical, or thermal properties that significantly impede the movement of water and <br /> air through the soil or that restrict roots or otherwise provide an unfavorable root <br /> environment. Examples are bedrock, cemented layers, dense layers, and frozen <br /> layers.The table indicates the hardness and thickness of the restrictive layer, both <br /> of which significantly affect the ease of excavation. Depth to top is the vertical <br /> distance from the soil surface to the upper boundary of the restrictive layer. <br /> Subsidence is the settlement of organic soils or of saturated mineral soils of very <br /> low density. Subsidence generally results from either desiccation and shrinkage, or <br /> oxidation of organic material, or both,following drainage. Subsidence takes place <br /> gradually, usually over a period of several years. The table shows the expected <br /> initial subsidence,which usually is a result of drainage, and total subsidence,which <br /> results from a combination of factors. <br /> Potential for frost action is the likelihood of upward or lateral expansion of the soil <br /> caused by the formation of segregated ice lenses (frost heave)and the subsequent <br /> collapse of the soil and loss of strength on thawing. Frost action occurs when <br /> moisture moves into the freezing zone of the soil. Temperature, texture, density, <br /> saturated hydraulic conductivity(Ksat), content of organic matter, and depth to the <br /> water table are the most important factors considered in evaluating the potential for <br /> frost action. It is assumed that the soil is not insulated by vegetation or snow and is <br /> not artificially drained.Silty and highly structured, clayey soils that have a high-water <br /> table in winter are the most susceptible to frost action.Well drained,very gravelly, <br /> 36 <br />
