Intended
Use
ADIEM (Advanced Dynamic Impact Extension Module) is a high-performance, redirecting,
energy-absorbing crash cushion and end treatment for portable and permanent protection of
concrete barriers, bridge parapet rail, bridge piers and other hazards. It is simply
installed with pins on a smooth surface in the same plane as the barrier on soil, asphalt
or concrete (ADIEM does not require any jobsite forming or pouring of a concrete pad).
For temporary or construction zone applications, the system may be easily relocated as
the work zone changes, and from project to project.
The energy absorption elements of the ADIEM are lightly reinforced, ultra low strength
perlite concrete modules. The ADIEM dissipates the energy of an impact as the light-weight
modules are crushed. Clean up and restoration of the system into full service are quick
and easy. Simply replace the damaged modules and minor sweep up of debris.
The redirection element of the system is a heavily reinforced concrete, variable height
curb with automobile hub-height tube rails.

ADIEM Base Repair Procedures
Tools required:
Normal concrete or masonry tools (trowels, brushes, forms, etc..) If needed specific tools can be listed, depending on severity of damage. A helpful hint: for most minor chips or damages try using Styrofoam forming which can be easily torn away after drying.
Material required:
Any standard highway concrete epoxy (10,000 psi or greater).
Dry cement (for aesthetics only, brand and strength not critical).
Clean cool water.
Sand
ADIEM base features
The ADIEM base unit has #6 reinforcing bars running
longitudinally continuous from the front to the rear of
the unit. The unit has #4 reinforcing bars running laterally
placed every 6" on centers. The track in the center
of the unit is made of 3/16" continuous material with
1/2" x 4" studs approximately every 6" on
centers. There are redirecting bumpers on each side of the
unit made of 3/16" material with 1/2" x 4"
studs approximately every 6" on centers. The base is
firmly held together with a concrete mixture of 4,500 psi
or greater.
ADIEM
base utility
The ADIEM base serves the purpose of providing
a secure holding line for the energy absorbing ADIEM modules.
The unit is designed with the intent of having performance
features based on specific angles and dimensions being held
constant. In repairing the unit it is important to realize
that minor chips and cracks, though aesthetically
displeasing, should not affect the performance of the system.
If the damage is greater than 2" deep or 6" long,
a Syro technical representative should be contacted for
assistance.
ADIEM
base repair
Use a brush to remove all loose material. Dampen
area with sponge or cloth prior to application. If needed
create a form to hold the mixture constant while drying
occurs. Mix the highway concrete epoxy according to the
directions given from the manufacturer. Apply mixture to
damaged area and allow drying to occur per the manufacturers
recommendations. Upon drying use a hammer or other rigid
device to firmly strike the patched area, checking the are
to be sure that proper bonding has occurred. After satisfactory
testing is complete, mix the cement, sand, and water to
create a "slurry," which can be applied with a
brush and blend with existing concrete on the ADIEM base.
ADIEM Module Repair Procedures
Tools
required
4" to 6" putty knife (to spread repair
mixture)
Small 1 to 2 gallon bucket or pan (to mix repair mixture)
3 to 5 gallon bucket (to mix the finish coat)
Paint Roller (to apply the finish coat)
Material
required
ADIEMcrete mixture
Perlite Granules
ADIEMcoat
Clean cool water
Surface
preparation
Remove loose material.
Dampen area with sponge or cloth prior to application.
ADIEMcrete
mixture
Mix approximately 1 pound of "ADIEMcrete" with approximately 6 ounces of clean cool water.
Mix thoroughly until "ADIEMcrete" mixture reaches a stiff paste consistency.
ADIEMcrete
application
Using putty knife or similar tool pack the "ADIEMcrete"
mixture the damaged area bringing the mixture to a smooth
level finish with surrounding area. If the damage penetrates
past the reinforcing cage or is no longer than six inches,
a Syro technical representative should be contacted for
assistance. "ADIEMcrete" mixture will set
in approximately 45 minutes.
ADIEMcoat
application
Insure that the "ADIEMcrete" mixture
has set prior to applying the "ADIEMcoat" finish.
Mix the Perlite granular material with the liquid "ADIEMcoat"
until a semi-stiff consistency is achieved.
Using a paint roller apply the "ADIEMcoat" finish
to the repaired area applying additional coats as necessary
to match the texture of the surrounding area.
