Cracks form
in asphalt from severe heat and water seeping through cracks. When the
temperature decreases, the water freezes, causing the cracks to expand. Sand
and dirt are also other components that cause the cracks to expand. It is very
important to get cracks properly filled as soon as possible to avoid expensive
repairs.
The type of
repairs depends greatly on the cracking patterns. Initially, asphalt cracks in
a longitudinal direction. As the damage progresses, the cracks take on either a
block or square pattern. When left untreated, the crack completely deteriorates,
and leads to heaving. At the heaving or “alligator” cracking stage, the asphalt
crack is no longer able to be filled, and must be replaced or patched.
OUR 3-STEP PROCESS:
• First, any ¼”
wide or larger cracks are routed, dried, and cleared using a forced air wand or
hot air lance. • Next, the
sealing material is protected by applying biodegradable paper to the area.
• Finally, a
3723 series rubberized hot crack seal material is used to properly seal the
cracks. To prevent overheating and scorching, a double jacked boiler and melter
are used during this process.
