Common Repairs Needed on Asphalt and Tarmac Surfaces

Asphalt and tarmac surfaces are durable, but over time, they inevitably require repairs to maintain their functionality and appearance. Some of the most common issues that arise may include:

Potholes

Potholes are a prevalent problem on asphalt surfaces, particularly on roads and car parks. They form when water infiltrates small cracks in the surface, weakening the base layers. As vehicles drive over these weakened areas, the asphalt collapses, creating a hole. Asphalt pothole repair is essential to fix these cavities, which can cause significant vehicle damage and safety hazards.

Cracks

Cracks in asphalt can develop for various reasons, including thermal expansion and contraction, heavy traffic loads, and natural ageing. If left untreated, small cracks can widen and deepen, eventually leading to more severe damage. Road crack repair is crucial to prevent water from penetrating the asphalt, which can accelerate the deterioration process.

Rutting

Rutting is a form of surface deformation where depressions develop in the wheel paths on the road. This issue is common on heavily trafficked roads, especially where the asphalt has not been adequately compacted. Asphalt surface repair is necessary to address these depressions, which can lead to poor drainage and hydroplaning risks.

Ravelling

Ravelling occurs when the aggregate within the asphalt surface starts to separate from the binder. This results in a rough, uneven surface that reduces traction and can make the road dangerous for vehicles. Asphalt repairs, including the application of bituminous repairing materials, are often required to restore the surface.

Edge Deterioration

The edges of asphalt surfaces are particularly vulnerable to damage, especially in rural roads and driveways where the support is minimal. Vehicles driving close to or over the edges can cause the asphalt to crack and crumble. Tarmac patch repair is a common solution to reinforce these areas and prevent further deterioration.

Patching Failures

Previous asphalt repair attempts, such as patching, can fail if not done correctly. Poor-quality patching materials or inadequate preparation can lead to the patch breaking down, allowing water to infiltrate and causing the damage to reoccur. Effective asphalt repair products are crucial for ensuring long-lasting repairs.

Surface Wear

Over time, the surface of asphalt can become worn, leading to a rough, uneven texture. This wear can result from constant vehicle traffic and exposure to the elements. Asphalt floor repair products can help restore the surface's smoothness, improving the ride quality and extending the surface's life.

Sinkholes

Sinkholes under asphalt surfaces are less common but can be extremely disruptive and dangerous. They usually occur due to subsurface issues, such as poor compaction or the collapse of underground infrastructure. Bitumen road repair products may be needed to address these serious issues and restore the integrity of the surface.

Discolouration and Fading

Exposure to UV rays and weather conditions can cause the asphalt surface to fade and lose its original colour. Red asphalt repair is often necessary in areas with coloured surfaces, such as bus lanes or cycle paths, to maintain the visual consistency and functionality of the surface.

Heaving and Buckling

In regions with significant temperature fluctuations, asphalt surfaces can heave and buckle due to freeze-thaw cycles. Water that infiltrates the surface freezes and expands, causing the asphalt to push upward. Road repair materials, including hot tar road repair products, are essential for fixing these issues and preventing further damage.

How These Issues Occur

The occurrence of problems with tarmac and asphalt can be attributed to a variety of factors, each contributing to deterioration of the surface over time. Understanding these factors is key to preventing and addressing issues effectively with specialist repair products.

Weather Conditions

Weather is one of the most significant factors affecting asphalt surfaces. Rain, snow, ice, and temperature fluctuations all play a role in the degradation process. Water is particularly damaging, as it can seep into cracks and joints, leading to freeze-thaw cycles that expand and contract the asphalt. In cold climates, this can cause heaving and cracking, while in warmer climates, prolonged exposure to heat can soften the asphalt and lead to rutting and deformation.

Traffic Load

The weight and frequency of traffic passing over asphalt surfaces are critical factors in their longevity. Heavy vehicles, such as lorries, buses, and construction equipment, exert significant pressure on the asphalt, which can lead to rutting, cracking, and eventual failure. Roads that experience high volumes of traffic are more likely to develop these issues, particularly if the asphalt was not designed to handle such loads.

Poor Installation

The quality of the initial installation of asphalt plays a crucial role in its durability. Improper compaction, inadequate thickness, or the use of substandard materials can all lead to premature failure. For example, if the asphalt is not compacted correctly, voids can form within the material, making it more susceptible to cracking and water infiltration. Similarly, if the base layers are not properly prepared, the entire surface can become unstable.

Ageing

Asphalt surfaces naturally age over time, and as they do, the binder that holds the aggregate together begins to oxidise and lose its flexibility. This process makes the asphalt more brittle and prone to cracking. While some level of ageing is inevitable, regular maintenance and timely asphalt repairs can extend the lifespan of the surface.

Subsurface Issues

Problems beneath the asphalt, such as weak subgrades, poor drainage, or shifting soil, can lead to surface damage. If the foundation is not stable, it can cause the asphalt to settle unevenly, leading to cracks, sinkholes, and other forms of deterioration. Subsurface issues are often the result of poor site preparation or natural geological changes over time.

Chemical Spills

Spills of chemicals, such as oils, fuels, and industrial solvents, can degrade the asphalt binder, weakening the surface and making it more susceptible to cracking and ravelling. These chemicals can penetrate the asphalt and break down the bonds between the aggregate and the binder, leading to rapid deterioration if not promptly addressed.

UV Exposure

Prolonged exposure to the sun's ultraviolet rays can cause the asphalt binder to oxidise and become brittle. This process, known as photo-oxidation, weakens the surface and makes it more prone to cracking and other forms of damage. UV exposure also contributes to the fading and discolouration of the asphalt, which can affect the overall appearance of the surface.

Tree Roots

Tree roots can be a significant problem for asphalt surfaces, particularly in residential areas where trees are planted close to driveways and sidewalks. As roots grow, they can exert pressure on the asphalt, causing it to lift and crack. Over time, this can lead to significant surface damage that requires extensive repairs.

Improper Drainage

Water is one of the most destructive elements for asphalt surfaces. If the drainage system is inadequate, water can pool on the surface or infiltrate the asphalt through cracks and joints. This water can then freeze and expand, causing the asphalt to crack and heave. Proper drainage is essential to prevent these issues and extend the life of the surface.

Heavy Machinery

The use of heavy machinery, particularly in industrial settings or during construction activities, can cause significant damage to asphalt surfaces. These machines exert extreme pressure on the surface, leading to cracking, rutting, and even complete failure in some cases. If the asphalt was not designed to handle such loads, or if it is already weakened, the damage can be severe and costly to repair.

FAQ’s

1. What is the difference between asphalt and tarmac?
• Asphalt and tarmac are often used interchangeably, but they are technically different materials. Asphalt is a mixture of aggregates (such as sand, gravel, and crushed stone) and bitumen, a sticky, black petroleum byproduct. Tarmac, short for tarmacadam, is a type of road surface made by coating crushed stone with tar. While both materials are used for paving roads and other surfaces, asphalt is more commonly used today due to its superior durability and performance.
2. How long does it take for asphalt repairs to cure?
• The curing time for asphalt repairs can vary depending on the type of repair, weather conditions, and the specific product used. In general, small crack and pothole repairs may take 24 to 48 hours to cure sufficiently for light traffic. However, full-depth repairs or larger patches may require several days to cure completely. It is advisable to follow the manufacturer's recommendations for curing times to ensure the repair lasts as long as possible.
3. Can asphalt be laid in cold weather?
• Asphalt can be laid in cold weather, but it requires special consideration. Cold weather can make it more difficult to achieve proper compaction, which is essential for the longevity of the asphalt surface. To combat this, hot mix asphalt can be used, or cold lay products specifically designed for low temperatures. However, laying asphalt in extremely cold conditions is not recommended unless absolutely necessary, as it can compromise the quality of the surface.
4. How often should asphalt surfaces be sealed?
• Asphalt surfaces should be sealed every two to three years to protect them from the elements and extend their lifespan. Sealing helps to prevent water infiltration, UV damage, and the effects of chemicals like oil and fuel. Regular sealing also keeps the asphalt looking fresh and new. However, over-sealing can lead to issues such as cracking, so it is important to follow a maintenance schedule that is appropriate for the specific conditions of the surface.
5. What should be done if tree roots are damaging the asphalt?
• If tree roots are causing damage to an asphalt surface, it is important to address the issue as soon as possible to prevent further damage. The roots may need to be trimmed or removed, but this should be done carefully to avoid harming the tree. In some cases, a root barrier can be installed to prevent the roots from growing under the asphalt in the future. After addressing the root issue, the damaged asphalt should be repaired to restore the surface.
6. Is it possible to repair asphalt during rainy weather?
• While it is possible to repair asphalt during light rain, it is not ideal. Moisture can prevent the repair materials from bonding properly with the existing asphalt, leading to a weaker repair that may not last as long. If repairs must be done in wet conditions, cold lay products designed for use in such weather should be used, and the area should be as dry as possible before starting the repair.
7. What are the signs that an asphalt surface needs to be replaced rather than repaired?
• There are several signs that indicate an asphalt surface may need to be replaced rather than repaired. These include extensive cracking (also known as alligator cracking), severe rutting, widespread potholes, significant drainage issues, and the overall age of the surface. If more than 25-30% of the surface area is damaged, it is often more cost-effective to replace the asphalt rather than attempt continuous repairs.
8. Can concrete surfaces be repaired with asphalt products?
• While it is possible to use asphalt products to repair minor damage on concrete surfaces, it is generally not recommended for larger repairs. Asphalt and concrete have different properties, and using asphalt on concrete may lead to poor adhesion and further damage. For best results, concrete-specific repair products should be used to address any issues on concrete surfaces.
9. Why does asphalt become slippery when wet?
• Asphalt can become slippery when wet due to a combination of factors, including the type of aggregate used, the smoothness of the surface, and the presence of oils or other contaminants. Over time, the asphalt binder can wear away, exposing more of the aggregate, which can reduce traction. Regular maintenance, including the application of anti-skid treatments, can help to reduce slipperiness and improve safety.
10. What is the impact of heavy traffic on asphalt surfaces?
• Heavy traffic can significantly impact asphalt surfaces by accelerating wear and tear. The constant pressure from heavy vehicles can lead to rutting, cracking, and deformation of the surface. Over time, this can result in the need for more frequent repairs and ultimately shorten the lifespan of the asphalt. Designing the asphalt with appropriate thickness and reinforcing the base layers can help mitigate the effects of heavy traffic.
