Asphalt pavement can be an invaluable investment that should be maintained accordingly to ensure long-term viability and minimize costs. Early repairs of minor damages will prevent more extensive and expensive repairs in the future and extend its lifespan. Select the best Greensboro Asphalt Paving.
Cracks allow water to seep beneath the surface and seep into cracks in pavement, leading to erosion that leads to alligatoring and pothole formation. Maintaining asphalt paving maintenance plans must include crack filling as a regular task.
Asphalt pavement consists of petroleum products mixed with rock. Over time, however, the petroleum dries out under sunlight’s UV rays and weathers away, leaving gaps between stones. These gaps allow water, oil, and other harmful substances to seep into asphalt, leading to cracks that eventually form potholes. Seal coating replenishes its oils to rebind it while protecting it against harmful elements like water and oil seeping in and seeping through; in doing so, it safeguards asphalt against cracking.
This process begins by spraying a bituminous-based or acrylic liquid formulation onto the surface of a driveway or parking lot, after which workers hand squeegee the asphalt to create a one-eighth-inch coating that dries to a black, glossy finish. They also flash heat any petroleum stains (gasoline and motor oil stains) to ensure good adhesion with their new coating.
Seal coating your asphalt pavement regularly can extend its lifespan and save money on replacement or repair. Sealcoating fills hairline cracks and tiny pits to block more damaging water or chemicals from entering, keeps out debris that could wear down its soft asphalt foundation, keeps out debris that causes wear-and-tear, keeps out dirt that wears down its base as well as keeps out debris and dirt that wear down soft asphalt bases beneath. However, seal coat alone cannot repair structurally compromised asphalt pavement; cracks or potholes still require professional repair or replacement from repair services or replacement by professionals.
Cracked areas allow water to seep beneath the surface and weaken the subbase, potentially leading to raveling or even asphalt failure. Restoring cracked areas early as part of preventive maintenance can extend the lifespan of asphalt surfaces significantly.
Before applying crack filler, contractors must adequately prepare and dry the area by either wire brushing or air blasting. This step is critical as it ensures that loose asphalt material, grit, and debris are entirely removed from cracks in asphalt pavement; additionally, it allows crack fillers to adhere more securely to surfaces while also helping prevent moisture seepage into them.
When working with emulsified crack filler, several consecutive dry days must occur before beginning application. This ensures the crack filler adheres securely to its target surface without washing away during rainstorms.
Shallow cracks typically measure less than half an inch deep and should be filled in using sand until they reach the correct depth before applying the crack filler. Deeper cracks should be repaired using rubberized hot pour crack filler melted by specialized crack repair machines before being applied directly onto each crack. Both methods are suitable for repairing block, edge, and reflective cracks as well as most transverse ones; neither technique, however, works well when dealing with alligator or longitudinal cracks that have formed across asphalt surfaces.
Asphalt pavements can crack and develop potholes over time due to freeze-thaw cycles, heavy traffic, or other factors deteriorating their surfaces. If these issues go unchecked, they will worsen and lead to complete asphalt failure, requiring expensive replacement costs.
Pothole repairs must be addressed quickly as they present a severe hazard to drivers, detract from property aesthetics, and damage vehicle tires. Professional intervention must ensure the correct process is followed for lasting results.
Potholes begin as tiny cracks that allow water to enter pavement layers through cracks. Freeze-thaw cycles cause this trapped water to expand and form potholes, which require regular patching in order to avoid their formation and severe other pavement distresses.
There are three primary asphalt patching methods: throw-and-roll, dig-out, and spray injection. Throw-and-roll requires using a truck equipped with an emulsion tank, aggregate tank, heating components, and high-volume blower to mix and apply asphalt to damaged areas temporarily if hot mix asphalt is unavailable or practical; dig-out patching provides more permanent solutions as it involves digging out affected areas to be replaced with fresh asphalt; while spray injection offers semi-permanent patching in cold or wet weather conditions.
An attractive asphalt surface adds value and welcomes residents, guests, and customers. Achieving that look requires consistent maintenance; its best methods depend on its size, location, and usage.

Linear cracking (also referred to as longitudinal cracking) occurs in joints of pavement due to age and daily temperature variations that cause asphalt to shrink or due to weak sublayer layers. To reduce or avoid linear cracking during construction, proper compaction must be ensured during the compaction process, as well as improving drainage around asphalt surfaces.
Raveling refers to the degradation of asphalt when its rocks and grit disintegrate over time, leaving behind uneven surfaces that create trip hazards as well as standing water. To combat raveling during construction and beyond, ensure your quality asphalt mix while regularly sweeping and weed-eating the area to remove any vegetation encroachment.
Alligator cracking, also known as load-related pavement damage, is identified by squares or circles of cracked pavement that do not respond to loading loads. It indicates improper installation and should be addressed by digging beneath the surface to detect its source and applying a deep overlay solution to strengthen it further. Asphalt experts advise using either hot mix asphalt patches or cold mix replacement solutions in order to repair alligator cracking effectively.
