Measurement of the R value of a soil is done with a stabilometer (AASHTO T 190 or ASTM D 2844). A stabilometer (Figure 5-13) is similar to a triaxial device consisting of a metal cylinder in which there is a rubber membrane; the annular space between the two is …Phone: (202) 366-1554

The “subgrade” is the in situ material upon which the pavement structure is placed. Although there is a tendency to look at pavement performance in terms of pavement structure and mix design alone, the subgrade can often be the overriding factor in pavement performance.

The AASHTO flexible pavement design equations currently used by WisDOT do not allow the direct input of DGI values to account for subgrade soil influence. In these equations, subgrade soil influence is represented by the factor termed Soil Support Value (SSV). Using experience, pavement performance, and judgment, WisDOT has

(AASHTO T-274) is quite time consuming. Before trying to understand the resilient modulus, the need to replace the soil support scale that was used in the previous AASHTO Interim Guide for Design of Pavement Slructures (2) should be recognized. The fundamental basis for both guides is the AASHO Road Test that was conducted in 1958-1960.

It is important to note that "the units of soil support, represented by the soil support scale, have no direct relationship to any procedure for testing soils" (AASHTO, 1972) and that it was left up to each agency to determine correlations between soil support and material testing procedures.Phone: (202) 366-1554
