Water is the most destructive element to pavement. When cracks occurred on
the pavement, surface water will infiltrate into the
pavement, reduced the adhesiveness of the asphalt. On the other hand, the water
in the binder course will transfer into high water pressure under the car load.
As time passes, surface course will come off in scales or layers. Cracksealing
technology fractures to stop water from entering the base course will lengthen
the pavement life by 3 to 5 years.
A proactive crack sealing approach is therefore the best solution in
order to avoid expensive maintenance and eventual pavement reconstruction.
Cracksealing is the process of creating a flexible, waterproof seal, in
and over a crack or joint to stop water and road debris from entering the crack
and causing further damage. The material used is a hot-applied polymer modified
asphalt sealant which is flexible enough to allow for expansion and contraction
of the pavement.
USING THE RIGHT EQUIPMENT is a significant part of any crack
sealing project. There are two major steps: crack grooving and sealant
application. Cracks have to be cleaned before grooving. Surface preparation can
be accomplished with a crackrouter and a hotair lance. In simple terms a heat lance uses hot, compressed air that
blows cracks clean while drying them out. Cutting the crack allows enough
sealant expansion and contraction. The reservoir also ensures that the proper
amount of sealant penetrates the crack. Esun crack routers can follow even the most random
pavement cracks with the crack indicator. Once the grooved is complete, simply
use compressed air to remove the dust created by the router.
Our crack sealingmachine configured melting tank with a recirculation heating system and 45
degree downward burner chamber along with oil-jacketed tank allows high heating
efficiency without coking sealant.
Considering of different elements which will affect the cracksealing
result, such as outside air temperature, wind velocity, humidity and direct sun,
it is necessary to choose the right sealant. CIMARY is a hot applied crack sealant of high
performance, consisting of synthetic polymer, recycled rubber, asphalt cement,
and other modifiers. The waterproof gel is solid at room temperature, and melt
into super-stretchable and adhesive liquid through heating. It can seal cracks
and joints in the pavement efficiently, quickly and lastingly. There are four types
of
CIMARY Crack Sealant adapt to different areas (see below).
