| LOAD SUPPORT USING MIRACELL CELLULAR
CONFINEMENT SYSTEM |
MiraCell(TM) cellular confinement system produces a semi-rigid
road base for effective horizontal load spreading and reducing
sub grade contact pressure. Extended road life is ensured
due to minimum surface deformation allowing increased load
repetitions.
Features and Benefits of the MiraCell Cellular
Confinement System
The MiraCell cellular confinement system improves the load-deformation
performance of granular infill materials due to the hoop
strength of individual cells, the passive resistance of
infill material in adjacent cells and vertical stress transfer
to adjoining cells. When compared to 2-dimensional sheet
reinforcement materials, the stiffness of the 3 dimensional
MiraCell system is significantly greater and does not require
initial deformation to support the design load.
The MiraCell cellular confinement system dramatically increases
the shear resistance of granular infill materials allowing
the use of lower aggregates (e.g. sand, gravel) to carry
concentrated loads that would otherwise require crushed
stone or bituminous mixes to prevent localized, near-surface,
shear failure. The cellular structure also distributes concentrated
loads to surrounding cells thus reducing the stress on the
sub grades directly beneath the load and the required total
thickness of the structure.
The MiraCell load support system can offer several advantages
over conventional solutions and alternative systems. When
very soft soils and/or heavy loads are a factor, the system
can reduce costs by reducing the required section thickness.
Where aggregate materials are expensive or unavailable,
the system can reduce costs by incorporating locally available
materials.
