ESTIMATING LIMITING DENSITIES OF MAINE SANDS

In an effort to find in the mass of test data some hidden or implied relationships between the easily measured gradation variables and the limiting densities of a granular soil, some of the grain size, particle distribution, and shape characteristics of cohesionless soils in Maine were statistically related to the maximum and minimum density as determined by ASTM Standard Method D-2049-69. The relationships may be used to predict the results that would otherwise be available only from density testing. Regression equations are recommended which provide a firm foundation for further study by generating preliminary relationships which may be extended to include a wider range of materials. These equations (if used within the limitations set forth) can be used as a preliminary estimate of the limiting densities of a sample and can provide a quick and easy method for checking and evaluating laboratory results. Comments are made on some of the procedures contained in the ASTM D-2049-69. These comments relate to sample segregation, the loss of fines occurring to varying degrees depending on the soil gradation, and the change of name of the procedure (since it determines only the limiting densities of a sand which in turn may be used to calculate relative density or other density indices).
