Pothole
Repairing Compound : Bondade TCU-31
The Need
|
Conventional asphalt-based tacking materials
such as hot asphalt-cement, cutbacks or emulsions cannot be applied without specialized
spraying and heating equipment. Coatings that are poorly bonded to the existing surface
can reduce the longevity of a repair. With current methods of repair, nearly half of the
potholes filled today will fail within six months. Bondade uses readily available spraying
equipment to wet the surface and develop a tenacious bond between the asphalt and the
existing substrate. |
Bondade patching agent being
applied to a pothole. |
| It is an environmentally safe and
non-hazardous material that may be used with hot or cold asphalt concrete, under
damp or dry conditions and on nearly all surfaces. |
The Technology
|
Bondade bond promoter is applied to the surface
of the repair area prior to placing the asphalt mix. It may be applied to either dry
or damp substrates after removing any loose debris from the repair area and standing water
must be removed prior to treatment. After
application of Bondade, the asphalt (cold or hot mix) can be applied immediately. Bondade
will work with the applied asphalt to displace water from the bond line and produce a
repair with enhanced long-term durability. This highly effective patch bonding system
extends the life of asphalt repairs without increased demands on labor, specialized
equipment or additional safety precautions. |
The Benefits
|
- Environmentally Safe and Stable Bond Promoter (Tack Coat)
- Easy and convenient to use - spray or brush on
- Cost Effective... Lasting up to 85% longer
- Non-flammable
- Non-combustible
- Non-toxic
- Not a source of hazardous fumes or vapors
- Non-irritating to the skin
|
Status
|
Developed by Transpo Industries, Inc., as
a solution of highly effective coupling agents designed to promote adhesion of
asphalts to a variety of substrates, the use of Bondade markedly extends the working life
of asphalt repairs by securing a firm water intensive bond between repair asphalt and the
base materials. Bondade can be used for
- Hot or cold patching
- Pavement overlays
- Damp or dry holes
- Emergency repairs
|
Barriers
|
Bondade should be used whenever new asphalt or
bituminous concrete is being applied to either concrete, asphaltic surfaces or potholes.
If the repair area is wet standing water must be removed prior to treatment or it will
dilute the applied Bondade and reduce its effectiveness. |
