Permanent Repairs, Not Temporary Fixes

Challenging the Misconception around Bagged Cold Lay Asphalt

Summary

For decades, bagged cold lay asphalt has suffered from a perception problem. Often viewed as a temporary solution suitable only for emergency repairs, many highway professionals and members of the public associate bagged materials with short-term fixes that quickly fail under traffic loading and extreme weathers.

However, this perception does not reflect the performance of modern, high-quality cold lay asphalt technologies.

When the correct material is selected and installed in accordance with manufacturer guidance, cold lay asphalt delivers durable, long-lasting repairs capable of withstanding the demands of a busy road network. In fact, independently tested and approved cold lay solutions have been successfully used by local authorities across Britain for nearly 50 years.

This paper explores “temporary repair” perception, examines the role of product quality and specification, and highlights why approved cold lay asphalt solutions continue to play a critical role in permanent highway maintenance strategies.

The Perception Problem

Anyone involved in highway maintenance will be familiar with public frustration surrounding pothole repairs.

Motorists often encounter failed repairs and naturally conclude that the materials used were inadequate or installed incorrectly. In many cases cold lay asphalt becomes associated with these failures because it is visible, readily available and commonly used during emergency maintenance operations.

As a result, widespread belief has developed that:

• Bagged cold lay asphalt is only suitable for temporary repairs.
• Permanent repairs require hot asphalt.
• Cold lay materials cannot withstand constant and heavy trafficking.

While these assumptions may have been influenced by experiences with lower-quality materials or poor installation practices, they do not accurately represent the capabilities of modern, independently approved cold lay asphalt materials.

Understanding Why Repairs Fail

The longevity of any road repair is influenced by multiple factors.

These include:

• The quality of the repair material.
• The condition of the surrounding road.
• The preparation of the repair area.
• Installation techniques.
• Traffic volumes.
• Weather conditions.

When repairs fail, the cause is often attributed to the quality of the material. In reality, failures frequently result from a combination of factors.

Just as not all hot mix asphalts perform identically, not all cold lay asphalts are created equal.

The key distinction lies in selecting products that have undergone rigorous independent testing and approval processes to demonstrate long-term performance.

The Importance of Independent Approval

Independent certification provides highway authorities and contractors with confidence that a product has been subjected to stringent testing and evaluation.

UltraCrete’s market-leading cold lay asphalt solutions are independently tested and approved through recognised industry schemes, including;

• BBA HAPAS approval
• PTS PAS approval.

These approvals assess critical performance characteristics, helping ensure products meet the requirements expected for highway maintenance applications.

Independent certification removes uncertainty from product selection and provides evidence-based assurance that a repair material can perform in real-world conditions.

Nearly 50 Years of Proven Performance

Performance is best measured not only in laboratory testing but also through successful long-term use on the road network.

UltraCrete cold lay asphalt solutions have been used on roads throughout the UK for nearly 50 years.

During this time, they have helped local authorities, utility contractors and highway maintenance teams carry out repairs across a wide variety of environments, including;

• Urban and rural roads.
• Footways and cycle paths.
• Utility reinstatements.
• Emergency repairs.
• Permanent maintenance programmes.

Today, UltraCrete products are supplied to more than 95% of local authorities across Britain, demonstrating widespread confidence in their performance and reliability.

This level is adoption would not be possible if cold lay asphalt were incapable of delivering long-term repair outcomes.

Permanent Repairs Require the Right Product

One of the biggest misconceptions surrounding cold lay asphalt is the assumption that all products offer the same level of performance.

In reality, significant differences exist between products available on the market.

When selecting a repair material, you should consider:

Independent Certification

Products should hold recognised approvals such as BBA HAPAS or PTS PAS where applicable.

Proven Track Record

Look for solutions that have demonstrated performance over many years in highway environments.

Ease of Installation

Products should be designed to support consistent installation and compaction, helping to keep repairs consistent on site.

Suitability for Application

The repair material must be appropriate for the specific maintenance requirement, traffic levels and road type.

Installation Matters

Even the highest-performing repair material can underperform if installed incorrectly. Best practice installation remains essential to achieving a durable repair.

Key considerations include:

• Proper preparation of the repair area, including saw cutting around the damaged area.
• Removal of loose and deteriorated material.
• Correct placement of repair material, including seal tack coat spray.
• Appropriate compaction.
• Always following manufacturer and SROH guidance.

When quality materials are combined with correct installation techniques, cold lay asphalt can deliver repairs that provide a permanent repair and reduce the need for repeat interventions.

Supporting Sustainable Highway Maintenance

Highway authorities continue to face increasing pressure to maintain our road network while managing budgets efficiently.

Permanent first-time repairs are critical to achieving these objectives. Repeat visits not only increase maintenance costs but also:

• Disrupt road users.
• Increase carbon emissions.
• Create additional traffic management requirements.
• Place further strain on maintenance resources.

By selecting proven, independently approved repair materials, authorities can improve repair longevity and reduce whole-life maintenance costs.

Conclusion

The perception that bagged cold lay asphalt is merely a temporary repair solution is outdated and does not reflect the performance of modern, independently approved products.

The reality is that when the correct cold lay asphalt is selected and installed properly, it can provide durable, long-lasting repairs that support permanent maintenance strategies.

For nearly 50 years, UltraCrete cold lay asphalt solutions have helped highway professionals across the UK deliver reliable repairs on some of the country’s busiest roads. Backed by independent approvals and trusted by over 95% of local authorities, UltraCrete continues to demonstrate that permanent repairs are not defined by how a product is supplied – but by how it performs.
