Asphalt Crack Sealing Tape: A Practical Guide for Pavement Repair
Asphalt crack sealing tape is a preformed pavement-repair material used to seal cracks and joints in asphalt surfaces. It provides contractors with an alternative to traditional liquid or hot-applied crack sealing methods and can be useful for maintenance projects where a clean, controlled overbanding application is preferred.
For contractors, choosing the right tape involves more than simply selecting a roll of crack repair material. Surface preparation, tape dimensions, pavement condition, installation method, heat bonding requirements, and traffic conditions all affect the finished result.
What Is Asphalt Crack Sealing Tape?
Asphalt crack sealing tape is a preformed sealing material designed to cover and seal pavement cracks or joints. Depending on the product, it may be manufactured from a rubberized asphalt or modified bituminous compound designed to remain flexible as pavement experiences normal movement.
These products are commonly used for:
- Asphalt crack repair
- Pavement joint sealing
- Parking lot maintenance
- Driveway repairs
- Road maintenance
- Crack-sealing preparation
- Preventive pavement maintenance
Crack sealing is an important pavement-maintenance practice because water entering cracks can contribute to further deterioration. The FHWA notes that crack sealing can be part of preventive maintenance and that treatment effectiveness depends on factors including material properties, installation methods, pavement conditions, climate, and traffic.
Why Use Crack Repair Tape?
Crack repair tape can provide contractors with a practical way to seal suitable pavement cracks without preparing and applying bulk liquid sealant.
Depending on the product and application, potential advantages include:
- Controlled material placement
- Consistent tape width
- Straightforward installation
- Reduced handling of liquid sealants
- Useful overbanding applications
- Convenient storage and transportation
- Consistent material thickness
Preformed tape products are available in different constructions, so contractors should always check the manufacturer's application requirements before selecting a product for a particular pavement condition.
What Is Rubberized Asphalt Crack Tape?
Rubberized asphalt crack tape combines asphalt-based material with rubber or polymer modifiers to provide a flexible sealing material.
The rubberized composition can be useful where the pavement experiences normal expansion, contraction, and movement. However, performance depends on the specific formulation and installation conditions.
Some preformed asphalt crack tapes are specifically designed to be heat-bonded to pavement. Similar products in the market describe the process as placing the tape over the crack and using a propane torch to activate the material and create the bond.
For buyers, it is important to distinguish a heat-bonded rubberized asphalt tape from a pressure-sensitive or cold-applied sealing tape. The installation requirements are not necessarily the same.
What Is Asphalt Joint Sealing Tape Used For?
Asphalt joint sealing tape can be used to seal suitable joints and cracks where water infiltration or pavement deterioration is a concern.
Typical applications include:
- Asphalt pavement joints
- Parking lot cracks
- Driveway joints
- Roadway maintenance
- Pavement repair areas
- Asphalt-to-asphalt joints
- Suitable asphalt-to-concrete transition areas
The exact application should be based on the tape manufacturer's specifications. Some joint-sealing tapes are designed for overbanding while others may have different installation requirements.
How Do You Install Asphalt Crack Sealing Tape?
Proper installation is essential for a reliable bond. For heat-bonded rubberized asphalt crack tape, contractors should follow the product-specific instructions.
A typical installation process is:
1. Clean the Surface
The pavement must be clean and completely dry before installation. Remove dirt, dust, loose aggregate, vegetation, oil, grease, and other contaminants that could interfere with bonding.
Surface preparation is especially important because moisture or loose debris can compromise adhesion. Technical guidance for asphalt crack-sealing products likewise emphasizes clean and dry pavement before application.
2. Position the Tape
Remove the release liner and center the tape directly over the crack or joint.
Make sure the tape is positioned correctly before applying pressure.
3. Press the Tape Into Position
Press the tape firmly onto the pavement so it remains properly positioned.
However, pressure alone is not sufficient for a heat-bonded product.
4. Heat the Tape Evenly
Use an appropriate propane torch to heat the tape evenly until the material properly activates and bonds to the pavement.
Move the flame continuously rather than concentrating heat in one area. Avoid overheating the material or damaging the surrounding asphalt.
Manufacturer instructions for comparable heat-bonded pavement tape products also specify propane-torch heating until the sealing material liquefies and bonds to the surface.
5. Roll or Press the Complete Surface
After heating, roll or press the complete tape surface to encourage proper contact with the pavement.
6. Allow the Tape to Cool
Allow the installed material to cool before permitting traffic. The required cooling period depends on the specific product, weather, pavement temperature, and manufacturer's instructions.
Why Is Heat Bonding Important?
Heat bonding is one of the most important considerations when installing a heat-activated asphalt crack sealing tape.
Simply peeling the liner, placing the tape, and applying pressure does not provide the same installation process as heat activation.
The purpose of heating is to activate the material so it can bond properly with the pavement surface. Comparable pavement tapes specifically instruct installers to apply heat after positioning and pressing the tape.
Buyer tip: If you're purchasing a heat-bonded tape, make sure your crew has the appropriate heating equipment and understands the manufacturer's temperature and installation requirements.
What Should Buyers Consider Before Purchasing Crack Sealing Tape?
Contractors should evaluate several factors before choosing a product.
Consider:
- Tape width and thickness
- Crack or joint size
- Pavement type
- Rubberized asphalt formulation
- Required installation method
- Heat requirements
- Surface preparation requirements
- Expected pavement movement
- Traffic conditions
- Product coverage
- Storage requirements
The most suitable tape is the one that matches the actual pavement condition and installation method rather than simply the lowest-cost option.
When Should Asphalt Crack Sealing Tape Be Used?
Asphalt crack sealing tape can be useful when contractors need to seal suitable cracks or joints using a preformed material.
However, not every pavement defect should be treated with tape.
Contractors should evaluate:
- Crack width
- Crack depth
- Crack movement
- Pavement condition
- Presence of vegetation
- Structural deterioration
- Moisture
- Existing sealant
- Traffic requirements
Large, structurally deteriorated, or severely failed pavement areas may require a different repair method. Proper pavement evaluation should come before selecting a sealing product.
Common Installation Mistakes to Avoid
Even a quality crack repair tape can perform poorly when installation is incorrect.
Avoid these common mistakes:
- Applying tape to wet pavement
- Leaving dirt or loose aggregate underneath
- Failing to center the tape over the crack
- Relying on pressure without heat activation
- Overheating one section of the tape
- Allowing traffic before the material cools
- Ignoring product-specific installation instructions
- Using tape on unsuitable pavement defects
Proper preparation and installation are just as important as the quality of the material.
How Should Contractors Maintain Areas Repaired With Crack Tape?
After installation, contractors should periodically inspect repaired areas for signs of deterioration.
Look for:
- Edge lifting
- Loss of adhesion
- Damage from traffic
- New cracking around the repair
- Material separation
- Surface contamination
- Water infiltration
Early inspection can help identify areas that require additional maintenance before minor problems become larger pavement repairs.
