Working Principle: Explains the "pressure-activated" mechanism — compaction activates the polymer-modified asphalt, aggregate interlocking locks in place, and bonds with the old pavement. Over time, solvents volatilize, and strength continues to increase.
Core Advantages:
- Zero heating → saves equipment cost All-weather → Not limited by weather conditions Instant traffic opening → does not affect traffic Compaction sensing → compaction is bonding Ultra-long shelf life → unopened 24 months
- Multi-purpose → potholes, trench backfill, cracks, etc.
Material Composition:
Polymer modified asphalt + Cold patch additive Graded aggregate (crushed stone, sand, filler material) biodegradable softener Zero VOC, no diesel solvents
Product Features
| # Feature | Explanation |

Application Scenarios
- Road/Highway Pothole Repair — Emergency and Planned Repair
- Parking Lot Maintenance — Commercial/Residential/Retail Parking Lots
- Municipal roads — Urban roads, intersections, sidewalks
- Industrial/Factory Ground — Factory roads, loading and unloading areas
- Pipeline Trench Backfill — Backfill after excavation for water/gas/electricity/telecommunications
- Residential/Community Roads — Property maintenance, school zone
- Airport apron/taxiway — Non-critical area repair
- Bridge deck/Ramp — Local repair
Construction Steps
| Step Operation | Key points | |
|---|---|---|
| 1 Clean out the pit Remove loose material and accumulated water, trim edges neatly, minimum depth 25mm | ||
| 2 Adhesive coating layer (optional) | Dry/dusty surfaces can be sprinkled with water or coated with emulsified asphalt. | |
| 3 filling material | Directly pour into the trench, superelevation 10-15mm | |
| 4 | flatten | Use a shovel/scraper to spread evenly |
| 5 Compaction | Plate compactor > Hand tamper > Vehicle rolling, deep pit layered compaction (each layer 50mm) | |
| 6 Open to traffic | Open to traffic immediately after compaction, avoid concentrated static loads within 48 hours. |
