Why is StreetBond™ Special?
High Polymer
Levels
-
1.1 Flexibility
Unlike concrete, the asphalt that
is used as the substrate for StreetPrint is a flexible
pavement. Asphalt expands and contracts as the temperature
changes. This is why no expansion joints are required for
StreetPrint™. StreetBond™ has the flexibility to move
with the asphalt, not against it! StreetBond™ will not
crack the asphalt.
-
1.2 Adhesion
Polymers are the glue that holds
StreetBond to the the asphalt surface. More glue means
better adhesion which means no pealing.
-
1.3 Abrasion Resistance
At lower polymer levels, the
polymer can’t form a continuum which means that the
components are not thoroughly bonded. At StreetBond’s
polymer levels a polymer continuum is formed. The polymer is
the primary component that holds the particles together
which results in higher abrasion resistance and a stronger,
more durable surface.
-
1.4 Color Stability
The polymers used in StreetBond are
very resistant to the effects of ultra violet light and the
high level of polymer in StreetBond helps to stabilize the
pigments so that the rich colors are retained over time.
-
1.5 Chemical Resistance
The polymers in StreetBond have
excellent resistance to chemicals like oil, gasoline, brake
fluid, transmission fluid, salt and food products. The
combination of the high polymer loading and the unusually
high build thickness created with StreetBond results in a
layer that significantly fortifies the asphalt.
-
1.6 Freeze Thaw Resistance
Higher polymer levels create a
tighter, hydrophobic (i.e. water repelling) surface. This
allows less water to penetrate into the surfacing system
which provides protection from degradation caused by freeze
thaw cycles.
Use of
(Specialized) Cements
-
2.1 Cure Time
StreetBond has a very thick film
compared to typical coating systems. Using cements reduces
the cure time by a factor of 6. This means a much faster
return-to-service. In addition, cement gives a rapid
internal cure which gives immediate mechanical bond to the
asphalt upon drying.
-
2.2 Abrasion Resistance
Using cements increases abrasion
resistance by a factor of 2 to 3.
-
2.3 Efflorescence
Using special cements reduces the
chances of efflorescence by a factor of 10.
-
2.4 Natural Appearance
-
Using cements provides abrasion
resistance without making the surface look plastic.
Use of Large
Aggregates
-
3.1 Build Thickness
The use of large aggregates allows
StreetBond to create a 3 dimensional aggregate structure
within the film compared to typical thin film coatings. This
increases durability and increases the strength of the
asphalt. In addition, chances of creating a continuous film
on an asphalt surface improve with greater build thickness.
This improves protection from solvents.
-
3.2 Slip and Skid Resistance
(Pendulum Test – Wet)
The use of large aggregates
increases both slip and skid resistance resulting in a safer
surface.
