Roadway and Roofing Repair Mixes and Compounds Based on Innovative Additives

Sripath® additives deliver high-performance options for asphalt repair and maintenance applications.

Sripath offers additives that can be used in a variety of asphalt repair and maintenance applications.

Repair and Maintain Asphalt Roadways and Roofs

Sripath asphalt additives help address deformations and damage to roadway surfaces.

Sripath additives can be used in pothole repair mixes and roofing repair formulations to restore and maintain aging asphalt and bitumen. Designed to rejuvenate oxidized materials, improve flexibility, and improve long-term performance, these additives can help extend the lifespan of existing pavements and building envelopes without the cost or disruption of full replacement.  

Sripath delivers reliable, cost-effective products that can be used for a variety of asphalt repair and maintenance uses such as repairing potholes, mitigating surface cracks, restoring aged membranes, and general wear.

Pothole Patching Mixes Using ReLIXER®

Use high levels of RAP when formulating roadway patches by dosing mixes with ReLIXER®. The asphalt rejuvenator restores the aged binder in the recycled aggregate and supports more cost effective, sustainable surface repair work.  

With ReLIXER®, contractors can incorporate high levels of RAP up to 100 % into pothole patching mixes for road repair applications. 

  • Used for both Hot Patch & Cold Patch Applications.

  • Mixes can be tailored to provide high stripping resistance.

  • Cold mixes have extended stockpile life.

  • Avoids use of cutbacks and petroleum-based solvents

ReLIXER can be used for pothole patching and repair.

Hot-In-Place Recycling Using ReLIXER®

ReLIXER can be used for hot-in-place asphalt recycling and roadway applications.

Hot In-Place Recycling (HIR) relies on restoring aged asphalt directly on the roadway. ReLIXER® is engineered to restore the functional properties of the aged binder in order to deliver a high-performance, durable roadway.  

As the existing pavement is heated and milled, it can be mixed with ReLIXER® in a mobile drum unit, allowing the aged binder to regain its functional characteristics. The rejuvenated high-RAP mix is then placed immediately to create a durable new road surface with minimal material waste. This approach also supports sustainability in asphalt by reducing hauling, conserving raw materials, and delivering a renewed roadway in a single pass. 

  • Applicable for structurally sound roadways with no base course damage.

  • Saves time and lower costs associated with reconditioning damaged roads 

  • Improves roadway performance and prevents further deterioration.

  • Promotes reclaimed asphalt recycling while reducing overall carbon emissions 

  • Allows for faster reopening of roadways to traffic 

Roof Repair & Maintenance

Roof repair and maintenance play a critical role in protecting buildings from weather and long-term structural damage.  

PGXpand®, NuMIXER®, and ReNUBIT® can be used to formulate high-performance roofing compounds to reinforce and repair vulnerable areas on new and aging roofs. These bitumen and asphalt additives enhance adhesion and durability to help seal high-stress areas like scuppers, vertical wall junctions, and roof penetrations. By improving long-term resilience and weather resistance, they can also help extend roof service life while reducing the need for frequent repairs. 

  • Great Roofing Repair and Mopping Compounds can be formulated.

  • Easy to incorporate additives into manufacturing process.

  • Additives lower viscosity, making it easier to manufacture & easy to apply.

  • Superior dosage efficiency.

  • Excellent low temperature ductility

PGXpand, NuMIXER, and RENUBIT are used for high-performance roofing compounds in repair and maintenance applications.

FAQs: Asphalt Repair and Maintenance

1. What is the role of asphalt and roofing additives in repair and maintenance applications?

Asphalt and roofing additives are used to restore aging materials, seal damaged areas, and improve long-term durability. They help extend pavement and roof lifespan by enhancing flexibility, adhesion, and resistance to weathering or deformations from use.

2. How do rejuvenators support pavement repair?

Asphalt rejuvenators restore the functional characteristics of the aged binder to improve workability and performance during repair processes. They can also help to more effectively integrated recycled materials.

3. What is hot in-place recycling and why is it used?

Hot in-place recycling (HIR) is a process that heats, softens, and rejuvenates existing pavement so it can be reconstructed on-site. It can reduce material waste and provide a cost-effective, more sustainable repair solution.

4. How do roofing additives help repair high-stress areas?

Roofing additives can strengthen compounds used to seal and reinforce vulnerable areas such as roof edges, penetration points, and vertical junctions. They can also improve adhesion and flexibility to prevent leaks and premature deterioration.

5. Can additives improve the longevity of existing roads and roofs?

Yes. Additives enhance the performance of repair materials, which can allow treated pavements and roofs to resist cracking and other deformations. This can result in longer service life and fewer maintenance requirements.

6. Are repair additives compatible with recycled materials?

Many advanced additives are specifically designed to work with recycled asphalt pavement (RAP) or reclaimed asphalt shingles (RAS). They help restore functional properties to improve performance while supporting sustainability goals.

7. Do additives help reduce lifecycle maintenance costs?

Yes. By improving the resilience mixes and patches used for repaired areas, asphalt additives can reduce the rework frequency and the time between maintenance cycles to lower overall lifecycle costs.
