Q. What types of stabilization does
Dunn Company perform?
A. Dunn Company uses Soil Modification
and Soil Stabilization, depending on the project needs.
Both processes typically utilize the in-situ soils mixed
with a choice of lime, cement, fly ash or a combination
of these materials.
Q. When is soil modification used
on a project?
A. Soil modification is used to enhance
the onsite soil characteristics to aid the contractor in
constructing a working platform for the construction of
building pads and paved areas. Modified soils are not considered
part of a pavement design or a permanent structure.
Q. When is soil stabilization used?
A. Soil Stabilization is used to enhance
either onsite or imported soil. Classifying soils as stabilized
requires a mix design prior to the start of the project.
Stabilized soils become part of the pavement design and
are permanent.
Q. What is Full Depth Reclamation?
A. FDR utilizes existing asphalt pavements,
oil and chip surfaces, rock bases or a combination of these
surfaces to stabilize an area. Dunn Company uses liquid
asphalt, asphalt emulsions, Ty 1 Portland cement and fly
ash for Full Depth Reclamation Projects. All Full Depth
Reclamation Projects require prior exploration of existing
material to be reclaimed and a full mix design to decide
which additive and percentage of additive is required to
stabilize the area. Lab and field verification are typical
for this type of construction.
