U. S. DEPARTMENT OF AGRICULTURE <br />'NATURAL kESUURCES CUNSERVATIUN SERVICE <br />fndnote -- CUNSTRUCTIUN MATERIALS <br />• <br />CUNSTkU(.iIUN MAifkIALS <br />PAGE 2 OF 3 <br />Od1211v8 <br />finis report gives information about the soils as a source of roadfill, sand, gravel, and topsoil. The soils are rated <br />'Good', 'fair', or 'Poor' as a source of roadfill and topsoil. They ere rated es a 'Probable' or 'Improbable' <br />source of sand end gravel. the ratings are based on soil properties end site features that affect the removal of the <br />soil end its use as construction material. Normal compaction, minor processing, and other standard construction <br />practices are assumed. Each soil is evaluated to a depth of 5 or 6 feet. <br />Roadfili is soil material that is excavated in one place and used in road embankments in another place. In this report, <br />the soils are rated as a source of roadfill for low embankments, generally less than 6 feet high end less <br />exacting in design then higher embankments. The ratings are for the soil material 6elcu the surface layer to e <br />depth of 5 or G feet. It is assumed that soil layers will be mined during excavating end spreading. Menr soils have <br />lacers of contrasting suitability within their profile. the report entitled Engineering Index Properties is also aveiiebie <br />and it provides detailed information about each soil layer. This information can help determine the suitability of each <br />layer for use es roadfill. The performance of soil after it is stabilized with lime or cement is not considered in <br />the ratings. <br />The ratings are based on soil properties, site features, and observed performance of the soils. The thickness of <br />suitable material is a major consideration. the ease of excavation is affected by large stones, a high eater table, <br />and slope. Hou cell the soil performs in place after it has been compacted and drained is determined by its strength (as <br />inferred from the engineering classification of the sail) and shrink-swell potential. <br />Solis rated 'Good' contain significant amounts of sand or gravel or both. They have at least S feet of suitable <br />material, a low shrink-swell potential, feu cobbles and stones, and slopes of 15 percent or less. Depth to the <br />water table is more than 3 feet <br />Soils rated 'Fair' have more than 35 percent silt- and clan-sized particles and have a plasticity of less than 10. <br />They have a moderate shrink-swell potential, slopes of 15 to 25 percent, or many stones. UeDth to the eater table is 1 <br />to 3 feet. <br />Soils rated 'Poor' have a plasticity index of more than 10, a high shrink-swell potential, many stones, or slopes of <br />more than 25 percent. They are wet, and the depth to the water table is less than 1 foot. These soils may have <br />layers of suitable material, but the materiel is less than 3 feet thick. <br />Sand and gravel are natural e99re9ates suitable for commercial use with a minimum of processing. Sand and <br />gravel are used in many kinds of construction. Specifications for each use vary widely. In this report only <br />the probability of finding material in suitable quantity is evaluated, The suitability of the materiel for specific <br />purposes is not evaluated, nor ere factors that affect excavation of the material. The properties used to evaluate <br />the soil as a source of sand or gravel are gradation of grain sizes (as indicated br the engineering classification <br />or the spill, the thickness of suitable materiel, and the content of rock fragments. Rinds of rock, acidity, and <br />stratification ere given in the soil series descriptions. Gradation of grain sizes is given in the Engineering Index <br />Propertle5 report. <br />A soil rated as a 'Probable' source has a layer of clean sand and gravel or a layer of sand or gravel that contains <br />up to 12 percent silty fines. This material must be at least 3 feet thick and less than 50 percent, by gei9ht, large <br />stones. All other soils are rated as an 'TmDroDable' source. Coarse fragments of soft bedrock, such as shale and <br />siltstone, are not considered to be sand end gravel. <br />
