Some of the more common outdated references to ASTM standards involve soil classification, soil plasticity, Proctor compaction tests
and the nuclear density gauge.
. Compaction tests
were carried out to assess the optimum water contents and maximum dry unit weights of sand-Al-Qatif expansive clay mixtures and sandbentonite mixtures.
Exova will carry out materials testing on fresh and hardened concrete, along with soil classification and compaction tests
There arc methods that are useful in this field of research, such as Proctor and uniaxial compaction tests
. The Proctor tests determines the maximum BD ([BD.sub.max]), and critical soil water content ([WC.sub.crit]), which represent the bulk density and moisture at which soil compaction is highest.
Results of Proctor compaction tests
of soil mixed with different percentages of L-SF.
To determine the moisture- density relationship, compaction tests
were carried out on 5 samples for T-1, 7 samples for T-2 and 8 samples for T-3.
The triaxial shear test samples were created according to the optimum water content determined from the compaction tests
SJB Services Inc., of Hamburg, performed compaction tests
on some of the backfilled excavations, according to records obtained by the Reporter.
In order to determine the compaction parameters corresponding to compaction energy, compaction tests
were conducted on soil sample imparting the specified compacting effort as presented in Table 2.
Manual 70 of the ASTM International manual series describes the different types of earthwork fills, the mechanics of compaction, laboratory compaction tests
for evaluating soils, and standard test procedures for determining the density of soil in place and the water content of soil.
The three papers on road widening report on foundation treatments, in situ dynamic compaction tests
on subgrade for reconstruction, and 3D finite element analysis of geosynthetic-reinforced and pile-supported widening of an embankment over soft soil.
Moisture potential and compaction tests
were conducted on soil 11-12 May 2004.
