Asphalt sealing, alternatively referred to as pavement sealing or road sealing, is a preventative maintenance method that includes applying a protective coating to the surface of asphalt pavements. This coating, typically made of bituminous materials and aggregates, creates a barrier shielding the underlying asphalt from damaging factors such as water infiltration, UV radiation, and chemical spills.
Asphalt sealing begins with thoroughly cleaning the road surface to remove dirt, debris, and loose material. Any cracks or potholes are repaired to create a smooth and even surface. The sealant is applied using specialised equipment, ensuring uniform coverage across the entire road. Once the adhesive dries and cures, it forms a durable protective layer that enhances the road’s overall performance and longevity.
Improving skid resistance
Skid resistance refers to the ability of a road surface to provide sufficient traction for vehicles, especially in wet or slippery conditions. When a road lacks adequate skid resistance, accidents increase as cars are more likely to skid or lose control. Asphalt sealing services address this issue by incorporating aggregates like fine gravel or sand into the sealant mixture. These aggregates create a textured surface that enhances tyre grip and improves skid resistance. The increased traction provided by a sealed road reduces the likelihood of vehicles skidding or hydroplaning, thereby minimising accidents.
Preventing pavement deterioration
Asphalt roads are subjected to various stresses, including traffic loads, weather conditions, and chemical exposure. These factors lead to cracks, potholes, and other surface irregularities that pose significant risks to road users.
Asphalt sealing is a protective barrier, preventing water and other damaging agents from penetrating the pavement structure. The underlying asphalt is shielded from moisture infiltration by sealing the surface, which is a significant cause of pavement deterioration. Sealing also helps to prevent the oxidation and hardening of the asphalt binder, which leads to cracking and ravelling of the road surface.
The northernhighwaysbitumen services for asphalt are crucial in preserving a uniform and smooth road surface, effectively preventing pavement deterioration. This preventive measure significantly reduces the formation of potholes, cracks, and other road hazards, which lead to accidents or vehicle damage. By ensuring roads are well-maintained, these services enhance safety and elevate the driving experience for all road users.
Enhancing visibility
Asphalt sealing services also play a role in enhancing road visibility, which is crucial for road safety. Asphalt roads fade and lose their dark colour due to exposure to sunlight and weather conditions. This fading makes it difficult for drivers to distinguish the road surface from its surroundings, especially during low-light conditions such as dawn, dusk, or inclement weather. Asphalt sealing restores the dark colour of the pavement, providing a clear contrast between the road surface and its surroundings. This improved visibility helps drivers navigate the road better, reducing the risk of accidents caused by poor visibility. The darker surface also helps reduce glare from sunlight or headlights, enhancing visibility and improving driver comfort.
Minimising maintenance disruptions
Asphalt sealing services not only enhance road safety but also contribute to minimising maintenance disruptions. When a road surface deteriorates, it often requires extensive or complete reconstruction. These maintenance activities lead to prolonged road closures, detours, and traffic congestion, increasing the risk of accidents and inconveniencing road users. Proactively sealing asphalt roads reduces the need for frequent and extensive repairs. Sealing helps extend the pavement’s lifespan, delaying significant rehabilitation work. This means that road users enjoy safer and smoother roads with fewer disruptions caused by maintenance activities.
