Custom Soil Resource Report <br />The soils are rated "good," "fair," or "poor" as potential sources of roadfill. The ratings <br />are based on the amount of suitable material and on soil properties that affect the ease <br />of excavation and the performance of the material after it is in place. The thickness of <br />the suitable material is a major consideration. The ease of excavation is affected by <br />large stones, depth to a water table, and slope. How well the soil performs in place <br />after it has been compacted and drained is determined by its strength (as inferred from <br />the AASHTO classification of the soil) and linear extensibility (shrink-swell potential). <br />Normal compaction, minor processing, and other standard construction practices are <br />assumed. <br />Numerical ratings between 0.00 and 0.99 are given after the specified features. These <br />numbers indicate the degree to which the features limit the soils as sources of roadfill. <br />The lower the number, the greater the limitation.
