The bearing value of the subgrade shall be determined
either by the CBR (California Bearing Ratio), plate bearing tests
or resistance value or the Engineering Soil Survey of New Jersey,
available from Rutgers University.
In this article the following definitions of
subgrade support are used:
Good subgrade soils retain a substantial amount of their
load-supporting capacity when wet. Included are the clean sands and
sand-gravels and those free of detrimental amounts of plastic materials.
Excellent subgrade soils are unaffected by moisture or frost. They
include clean and sharp sands and angular gravels, particularly those
that are well-graded. The CBR value of these soils is normally over
10, R-Value is 62 and above.
Subgrade soils which retain a moderate degree of firmness
under adverse moisture conditions. Included are such soils as loams,
silty sands and sand-gravels containing moderate amounts of clays
and fine silts. Normally the CBR value of these soils falls in the
range of 5-9, with an R-Vaule ranging from 50-61.
Subgrade soils, which become quite soft and plastic when
wet. Included are those soils having appreciable amounts of clay and
fine silt. The coarser silts and sandy loams also may exhibit poor
bearing properties in areas where frost penetration into the subgrade
is encountered for any appreciable periods of time. Normally the California
Bearing Ratio (CBR) value of these soils falls in the range of 2-4,
with an R-Value ranging from 25 to 45.
