Product Introduction
Two-component water-based rubber asphalt crack filler is a new cold-applied material specifically designed for road crack repair, waterproof sealing, and preventive maintenance. The product consists of Component A—liquid rubber asphalt material—and Component B—fine sand particles—and is applied after mixing and stirring the two components in the specified ratio.
The mixed material exhibits excellent fluidity, fillability, and bonding performance, enabling rapid penetration into cracks to form a flexible and dense waterproof sealant layer that effectively prevents rainwater infiltration and further crack propagation.
This product is suitable for various road crack repair scenarios, including asphalt pavements, concrete pavements, bridge decks, parking lots, and industrial park roads.
Product Features
Two-Component Reinforced Structure
The liquid component provides excellent adhesion and waterproofing performance, while the fine sand component enhances fillability, abrasion resistance, and compressive strength, resulting in more stable and long-lasting repair performance.
No Heating Required – Cold Application
Construction requires no heating equipment, involves no open flame operations, and the material can be mixed on-site for immediate use—making construction safer and more environmentally friendly.
Strong Adhesion
The material can be firmly bonded to base layers such as asphalt and cement, making it resistant to peeling off or being dislodged by vehicles.
Excellent Waterproof Performance
Forms a continuous waterproof layer to effectively prevent rainwater from penetrating the base course and reduce the further expansion of pavement distresses.
Flexible and Crack-Resistant
Maintains excellent elasticity after curing, adapting to road thermal expansion and contraction as well as vehicle load variations.
Wear-Resistant and Pressure-Resistant
Forms a stable skeletal structure after adding fine sand particles, suitable for areas with frequent vehicle traffic.
Easy Installation
Simple operation reduces labor and equipment costs, suitable for rapid maintenance construction of municipal roads.
Application Scope
- Asphalt Pavement Crack Repair
- Cement pavement crack sealing
- Bridge deck waterproofing and sealing
- Parking Lot Crack Repair
- Industrial Park Road Maintenance
- Neighborhood road maintenance
- Expressway preventive maintenance
- Pavement Joint and Expansion Joint Treatment
Instructions for Use
1. Crack Cleaning
Remove dust, soil, loose particles, and debris from inside the crack.
2. Hybrid Materials
Mix the liquid component and fine sand particles component thoroughly in the specified ratio.
3. Crack Injection
Slowly pour the mixed material into the crack to ensure complete filling.
4. Surface Leveling
Use a scraper or trowel to level the surface.
5. Natural Curing
Traffic can be opened once the material has cured naturally.
Product Advantages
Compared with traditional hot-melt crack sealing materials, this product does not require heating during application, reducing equipment investment and construction risks; compared with ordinary single-component materials, its two-component structure offers higher strength, superior compressive resistance, and a longer service life.
The product features multiple performance attributes, including waterproofing, sealing, flexibility, and wear resistance, making it especially suitable for rapid road maintenance and long-term protection requirements in modern road infrastructure.
