When Riding Over Crack Sealant Or Tar Strips

Riding a motorcycle brings a unique sense of freedom and connection to the road, but it also demands heightened awareness and skill. Among the many road hazards motorcyclists encounter, crack sealant and tar strips often pose a significant challenge. These seemingly innocuous patches of repair material can dramatically alter a motorcycle's handling, leading to unsettling wobbles, loss of traction, and, in the worst cases, accidents. Understanding how crack sealant and tar strips behave under a motorcycle's tires, and mastering techniques for safely navigating them, is crucial for every rider's safety and confidence. This comprehensive guide will delve into the properties of these road repairs, the dangers they present, and provide practical advice on how to ride over them with greater control and security.

Understanding Crack Sealant and Tar Strips

Crack sealant and tar strips are commonly used in road maintenance to prevent water from penetrating the pavement and causing further damage. While they serve an essential purpose in preserving road infrastructure, their composition and application can create hazardous conditions for motorcycles.

• Composition: Crack sealant is typically a rubberized asphalt emulsion or a hot-applied polymer-modified asphalt. Tar strips, also known as tar snakes or asphalt sealant strips, are pre-formed asphalt-based materials that are heated and applied to cracks.
• Application: Crack sealant is applied directly into cracks and crevices, often creating a raised surface that protrudes slightly above the surrounding pavement. Tar strips are laid over cracks and then heated to create a seal. Both methods aim to create a flexible, waterproof barrier.
• Surface Characteristics: Both crack sealant and tar strips tend to be smoother and more pliable than the surrounding asphalt, especially in hot weather. This difference in surface texture is a major factor in the challenges they pose to motorcycles.

The Dangers to Motorcyclists

The primary danger of riding over crack sealant and tar strips lies in their reduced coefficient of friction, particularly when they are hot or wet. This can lead to several issues:

• Reduced Traction: The smooth, pliable surface of the sealant offers less grip than the surrounding asphalt. This is especially problematic when braking, accelerating, or leaning into a turn. The tires can easily lose traction, causing the motorcycle to slip or slide.
• Wobbling and Instability: The raised profile of crack sealant can create an uneven surface that disrupts the motorcycle's balance. As the tires roll over these bumps, they can cause the handlebars to wobble or the entire bike to feel unstable. This is exacerbated at higher speeds or when the sealant is applied unevenly.
• Hydroplaning: In wet conditions, crack sealant can become extremely slippery. Water can accumulate on the smooth surface, creating a thin film that causes the tires to hydroplane. This results in a significant loss of control and can be particularly dangerous in curves.
• Unexpected Movement: Because sealant and tar strips are usually applied in lines that run in the same direction as the road, when the rider does not see them or expect them, the bike can have an unsettling side-to-side wiggle as the wheels pass over them. This can cause the rider to tense up, and can become dangerous.

Pre-Ride Preparation

Before embarking on a ride, especially in areas known for road maintenance, it's wise to take a few precautions:

• Tire Condition: Ensure your tires are properly inflated and have adequate tread depth. Properly inflated tires provide better contact with the road surface and improve traction. Worn tires are more susceptible to slippage on smooth surfaces.
• Suspension Setup: Adjust your motorcycle's suspension to match your weight and riding style. Proper suspension settings can help absorb bumps and maintain stability when encountering uneven surfaces.
• Check Weather Conditions: Be extra cautious when riding in hot or wet weather. Hot weather softens crack sealant, making it more slippery, while wet weather increases the risk of hydroplaning.
• Plan Your Route: If possible, research your route ahead of time to identify areas known for road maintenance or poor road conditions. This allows you to anticipate potential hazards and adjust your riding accordingly.

Techniques for Safely Riding Over Crack Sealant and Tar Strips

Mastering the following techniques can significantly improve your ability to safely navigate crack sealant and tar strips:

• Relax and Look Ahead: One of the most important principles is to remain relaxed on the motorcycle. Tensing up can amplify the effects of bumps and wobbles. Look ahead to anticipate the sealant or tar strips and plan your path accordingly. Avoid fixating on the immediate area in front of your tire.
• Maintain a Steady Speed: Avoid sudden acceleration or braking when crossing crack sealant. Maintain a steady, moderate speed to minimize the risk of losing traction. Abrupt changes in speed can upset the motorcycle's balance and increase the likelihood of a slip.
• Keep the Motorcycle Upright: If possible, try to cross crack sealant when the motorcycle is upright. Avoid leaning into a turn while riding over sealant, as this reduces the contact patch of the tires and increases the risk of a slide. If you must lean, do so smoothly and gradually.
• Light Grip on the Handlebars: Maintain a light grip on the handlebars. A death grip can amplify any wobbles or vibrations caused by the sealant. Allow the handlebars to move slightly as the tires roll over the uneven surface.
• Use Smooth Inputs: Make smooth, deliberate inputs to the throttle, brakes, and steering. Avoid jerky movements that can upset the motorcycle's balance. Smooth inputs provide better control and reduce the risk of losing traction.
• Shift Your Weight: Shifting your weight slightly in the direction you want to go can help maintain balance and control when crossing crack sealant. This is especially helpful when riding in a straight line.
• Avoid Sealant When Possible: The safest approach is to avoid riding over crack sealant altogether. Scan the road ahead and choose a path that minimizes contact with these surfaces. This may involve slightly altering your lane position or riding on a different part of the road.
• Cross at an Angle: If you cannot avoid riding over crack sealant, try to cross it at a slight angle. This reduces the amount of tire surface in contact with the sealant at any given time, minimizing the risk of a slide.
• Be Prepared for a Wobble: Even with the best techniques, you may still experience a wobble or vibration when riding over crack sealant. Be prepared for this and avoid overreacting. Maintain a relaxed grip on the handlebars and allow the motorcycle to stabilize itself.
• Practice in a Safe Environment: Find a safe, controlled environment to practice riding over uneven surfaces. This will help you develop the skills and confidence needed to handle crack sealant and tar strips on the road.

Advanced Techniques for Challenging Situations

In some situations, simply avoiding crack sealant may not be possible. Here are some advanced techniques for handling more challenging conditions:

• Cornering on Sealant: Cornering on crack sealant requires extra caution. Reduce your speed before entering the turn and lean smoothly and gradually. Avoid making any sudden changes in lean angle or throttle input. If possible, try to keep the motorcycle as upright as possible while still maintaining a safe cornering line.
• Braking on Sealant: Braking on crack sealant is particularly dangerous. If you need to brake, do so gently and progressively. Avoid locking up the wheels, as this can cause a slide. Use both the front and rear brakes, but apply them smoothly and evenly.
• Wet Conditions: Wet conditions significantly increase the risk of hydroplaning on crack sealant. Reduce your speed even further and maintain a greater following distance. Be extra cautious when cornering or braking. Consider using rain tires, which provide better traction in wet conditions.
• Heavily Sealed Roads: Some roads are covered in extensive networks of crack sealant, making it nearly impossible to avoid. In these situations, focus on maintaining a steady speed and smooth inputs. Be prepared for constant wobbles and vibrations. Consider avoiding these roads altogether if possible.

Understanding the Science Behind It

The physics behind the dangers of crack sealant and tar strips involves the principles of friction, adhesion, and tire dynamics.

• Friction: Friction is the force that opposes motion between two surfaces in contact. The amount of friction depends on the materials of the surfaces and the force pressing them together. Crack sealant and tar strips typically have a lower coefficient of friction than asphalt, meaning they offer less resistance to sliding.
• Adhesion: Adhesion is the force that attracts two surfaces together. Tire traction relies on adhesion between the tire rubber and the road surface. The smooth surface of crack sealant reduces adhesion, making it easier for the tire to slip.
• Tire Dynamics: Motorcycle tires are designed to deform slightly under load, increasing the contact area with the road. This deformation is essential for generating traction. However, when a tire rolls over crack sealant, the reduced friction can cause the tire to slip or lose its grip, disrupting the motorcycle's balance and control.
• Hydroplaning: Hydroplaning occurs when a tire encounters more water than it can dissipate. The water pressure builds up in front of the tire, lifting it off the road surface and causing a loss of traction. The smooth surface of crack sealant makes it easier for water to accumulate, increasing the risk of hydroplaning.

The Role of Motorcycle Technology

Modern motorcycle technology can help mitigate some of the dangers of riding over crack sealant:

• Anti-lock Braking System (ABS): ABS prevents the wheels from locking up during braking, which can be especially helpful on slippery surfaces like crack sealant. ABS allows you to maintain steering control while braking, reducing the risk of a slide.
• Traction Control System (TCS): TCS limits wheel spin during acceleration, preventing the rear tire from losing traction. This can be beneficial when accelerating on crack sealant, as it helps maintain stability and control.
• Riding Modes: Some motorcycles offer different riding modes that adjust the throttle response, ABS, and TCS settings. Selecting a rain or road mode can provide more conservative settings that are better suited for slippery surfaces.
• Suspension Adjustments: Electronically adjustable suspension allows you to fine-tune the suspension settings to match the road conditions. Increasing the suspension damping can help absorb bumps and maintain stability when riding over crack sealant.
