Asphalt repairs depend on the nature and extent of damage sustained to your pavement. Therefore, you must regularly inspect it and address any damages as quickly as possible. Choose the best Asphalt Paving Contractors Long Beach.
Surface patching can effectively repair minor damages that extend only one to two inches into the asphalt layer, providing a cost-effective repair option. However, for more extensive damage, full-depth patching may be more appropriate.
Sinkage
Asphalt pavement that has turned light gray indicates it has aged considerably and may be susceptible to freeze-thaw damage, drainage issues, and heavy vehicle use. Usually, this means an underlying problem such as poor subgrade conditions, insufficient gravel supply, or contamination in its mix requiring complete asphalt repair, including the installation of new base layers and heavy-duty pavement layers.
Sinking spots or heaves of asphalt are obvious telltale signs that your surface requires repair. They’re often caused by drainage issues that allow water to accumulate for extended periods, causing the asphalt to wear down slowly while potentially beginning a freeze-thaw cycle that further damages it.
To address this problem effectively, the best course of action is to address drainage issues immediately before they have an adverse impact on your parking lot. An excellent stormwater system can ensure water flows away efficiently rather than pooling on asphalt surfaces.
Cracked pavement may also indicate damage that needs immediate attention; alligator cracking, commonly referred to as alligatoring, can become serious if left unaddressed. Crack fillers or seal coating should address the issue; in more extreme cases, a contractor can perform full-depth patching to replace affected sections with fresh asphalt surfaces completely.
Chemical Spills
Asphalt degrades naturally over time, but when chemicals such as diesel oil, motor oil, gasoline, and antifreeze are introduced, it accelerates this process significantly. Diesel and motor oil, gas, and antifreeze can all contribute to breaking down asphalt when left uncovered, as well as eroding binding agents within its layers. Therefore, timely cleanup of chemical or oil spills is imperative in mitigating further potential damages to pavement surfaces.
Water is one of the significant contributors to asphalt pavement deterioration, particularly if its drainage systems are failing. Standing water softens underlying layers and weakens structures over time; penetrating water may even cause cracking and potholes. Our team will assess your asphalt’s condition to make sure all drainage systems are working effectively before providing preventative measures such as regular seal coating to keep its surface in top shape.
Edges of asphalt pavements can quickly deteriorate due to increased traffic and weather exposure. Therefore, you must regularly walk the perimeter of your pavement in search of signs of wear or damage and repair these spots with either patching or complete depth repair techniques as soon as you notice dimpling or depression in the surface of the parking lot – an indication of compromised asphalt that should be addressed immediately.
Edge Cracks
Cracked pavement edges often form due to soil erosion, lack of lateral support, drainage problems, heavy vegetation growth near the edge, and traffic overload. Although edge cracks can be temporarily repaired using asphalt crack fillers or emulsions, for long-term fixes, we must address the source of this issue – the soil or subgrade materials – and make permanent repairs.
Linear and longitudinal cracking is commonly referred to as alligator cracking due to their interconnecting shape resembling alligator skin. It occurs due to load-related deterioration caused by weak bases, inadequate asphalt thickness, or overloading pavement surfaces; cracks should be repaired by stripping away old surface material before repainting with fresh asphalt layers.
Reflection cracking occurs along the surface of a pavement and mirrors either sub-layer cracking, shifting in sub-layer joints, or both. These straight and often grid-patterned cracks should be filled in with sealants and asphalt fill products in order to keep moisture out and prevent further damage to underlying layers. We advise filling these cracks with sealants or asphalt fill products so as to keep moisture out and stop further damage – Fatigue cracking, on the other hand, is identified by numerous small cracks appearing in localized areas and indicates design/installation flaws as well as chronic excessive loads, poor drainage or dramatic temperature fluctuations; typically, full depth patching to reinforce and prevent further damages to the asphalt surface.
Fatigue Cracking
Fatigue cracking is an unfortunate yet widespread phenomenon on asphalt pavements, usually starting around the perimeter and slowly spreading inward over time. It may be caused by too thin an asphalt layer being subjected to loads it wasn’t designed for, as well as daily temperature variations or daily traffic loads being carried above what they should.
Cracked hot mix asphalt (HMA) is often caused by applying more stress than is designed into it, leading to cracking that needs immediate repairs. Cracking is often seen as a telltale sign of degradation that needs immediate rectification.
Moderate severity fatigue cracking is distinguished by connecting cracks that feature an alligator pattern, often appearing zig-zag-shaped. Swollen portions may even form, exposing lower layers of road materials. Repairing this issue usually requires the removal and replacement of affected portions of pavement.
Block cracking is a type of asphalt cracking that occurs as large interconnecting rectangles that spread over time, often as a result of poor quality or not flexible enough asphalt installation to accommodate temperature changes. Block cracks may also indicate improper sub-base or surface layer layers as well as heavy traffic loads, age hardening, or poor drainage conditions exacerbated by poor drainage or inadequate sub-base or surface layers – yet can often be addressed with simple crack filling or sealing techniques.
