:Crack
Sealing
To properly seal a crack, we first use heat-lance equipment to super-heat
and clean the crack. This allows for superior adhesion of our direct-fire
rubber. We also provide cold crack sealer.
How do APSHALT cracks
happen?
First Stage
The freeze/thaw process and natural expansion will eventually cause cracks
to appear.
Second
Stage
The surface becomes brittle, tiny hairline cracks appear. Aggregate raveling
creates rough patches on the surface.
Third
Stage
Cracks deepen into the subsurface, further damaging the integrity of the
asphalt. Water penetration into the crack and into the subtrate will widen
the crack. If unattended it will eventually create a pot hole as shown
below.
