At present, crack pavement repair faces prominent difficulties, and conventional crack repair technologies have widespread defects. Potholes are scattered, random and small in volume, and patching with cold patch materials delivers a short service life. Manual paving and compaction are time-consuming, labor-intensive and inefficient. Manhole cover perimeter repair suffers from insufficient compaction and easy damage due to poor joint treatment. In addition, backfilling asphalt mixture after crack excavation relies on manual paving, resulting in low construction efficiency and a long traffic opening waiting time.
To solve the above difficulties in crack treatment, our company independently developed the innovative SCT Self-leveling Crack Treatment Technology.
① High asphalt content endows the mixture with favorable deformability and crack resistance, delivering excellent resistance to low-temperature cracking and fatigue cracking; ② Optimized high-elastic modified SCT asphalt is adopted to further improve the crack resistance performance.
2. Adopts self-improved COOPER equipment
3. Equipment and Personnel
Advantages: ① Mobile with good flexibility and improved efficiency; ② Comprehensive maintenance vehicle integrating heating, heat preservation and transportation functions; ③ Equipped with an automatic metering system for stable and fast operation; ④ The hot asphalt mixture features high and low temperature stability, zero voids and excellent water damage resistance; ⑤ Compaction-free, easy construction and low traffic delay cost.
